State issues Notice of Violation to NFS Erwin nuclear fuel plant related to break of main fire water loop
On May 18, 2018, the Tennessee Division of Water Resources issued a Notice of Violation to NFS, which is referred to in NFS' Response to Notice of Violation of May 31, 2018:
"On Thursday, May 3, 2018, NFS experienced a break in the main fire water loop due to construction activities. The damage to the pipe occurred as construction personnel were excavating an area in preparation for a concrete pad. The fire water loop is fed by city water. The break in the fire water pipe caused water and soil to be displaced into the nearby storm drainage system. The water was isolated by closing certain valves within the NFS fire water loop system. The estimate of water loss was between 5,000 to 7,000 gallons. The estimated volume of soil displaced was approximately 1 cubic yard. As a precaution, the storm water drainage system gate had been closed prior to the beginning of excavation. The vast majority of the water and soil was contained within the storm drainage system; however, the gate does not fully prevent seepage and was partially opened for a short period to prevent the flooding of an adjacent building."

Unplanned reaction involving uranium at NFS Erwin nuclear fuel plant prompts special NRC inspection
An unplanned chemical reaction involving uranium at Nuclear Fuel Services has prompted a special federal inspection slated to begin Tuesday (Apr. 14) at the Erwin nuclear processing plant.
The reaction occurred April 4 in a 2-liter bottle stored in an access-controlled storage area. The bottle contained cleaning materials, some nitric acid and a small amount of uranium. It resulted in no employee exposures or injuries, the Nuclear Regulatory Commission reported in a news release.
(Johnson City Press Apr. 13, 2015)
NRC issues Notice of Violation on unplanned reaction involving uranium at NFS Erwin nuclear fuel plant:
On July 28, 2015, NRC issued a Notice of Violation to NFS, as "the licensee failed to ensure that procedure SOP-401-17, FMF Cleaning, Revision 7, contained inadequate
instructions for disposition of radioactive wastes, specifically for handling radioactive waste contaminated with non-compatible cleaning materials. As a result, an unplanned and uncontrolled chemical reaction occurred within an unoccupied storage area. If a worker(s) had been present in the area at the time of the event, there existed the
potential of a radiological or chemical consequence to the worker(s) that would be of low safety significance."

After more than ten years, NRC returns Nuclear Fuel Services facility in Erwin, Tenn., to normal agency oversight and inspection
The Nuclear Regulatory Commission issued the Licensee Performance Review for the Nuclear Fuel Services facility in Erwin, Tenn., and the recent performance documented in that review has led the agency to return NFS to the normal level of oversight and inspection for NRC-licensed facilities of the same type.
In 2004, the NRC increased its oversight of the facility, including the addition of a second resident inspector, based on the facility's performance and ongoing changes. Since that time, the agency has kept that increased level, but sustained improvement over the past several years, verified by NRC inspections, led to the conclusion that a return to the normal or core oversight level is warranted.

NRC begins special inspection at NFS Erwin nuclear fuel plant after violation of safety procedures
The Nuclear Regulatory Commission is launching a special inspection today at the Nuclear Fuel Services fuel fabrication facility to assess the circumstances surrounding the alleged improper disabling of safety devices in violation of NRC regulations.
The plant, located in Erwin, Tenn., fabricates fuel for the U.S. Navy's nuclear fleet.
On June 17, an employee was observed by an NFS supervisor to be improperly operating two valves that are identified as key safety devices. The valves were propped open, which rendered them unable to perform their intended safety function. They are intended to be manually operated to prevent a hazardous chemical solution from spilling on the floor and causing a chemical exposure. No radioactive materials were involved in the incident.
(NRC July 10, 2014)
NFS failed to file a proper report within one hour of the incident. As a result of the entire situation, NFS was cited for two violations: failing to make a report within the required time frame and circumvention of safety related components.
(Erwin Record Oct. 8, 2014)
On April 17, 2015, NRC issued a Notice of Violation to NFS: "...on June 17, 2014, an operator willfully violated licensee procedure SOP 401-22-302, Building 302 Area B, Step 4.2.8 Note when he held open self-closing valves 302-BA-0B01 and 302-BA-0B85 by means other than holding the valve handle. The circumvention of the self-closing isolation function of both valves resulted in unavailability of IROFS [items relied on for safety] and reduction in IROFS controls, respectively, for two potential high consequence events: chemical exposure and nuclear criticality safety."
The Nuclear Regulatory Commission staff is implementing a National Academy of Sciences committee's recommendation to perform a pilot study of cancer risk in populations around six U.S. nuclear power plant sites and a nuclear fuel facility. The NRC is asking the Academy to carry out this effort, which will help the agency determine whether to extend the study to the remaining U.S. reactor and certain fuel cycle sites.
In April 2010, the NRC staff requested the National Academy of Sciences (NAS) to perform a study on cancer mortality and incidence risks in populations living near NRC-licensed facilities to update the 1990 National Cancer Institute (NCI) report on "Cancer Risks in Populations near Nuclear Facilities." The study was divided into two phases. In Phase 1, NAS explored the feasibility of conducting an updated study by developing modern methods to perform the analysis. The staff has reviewed the results of the Phase 1 study and the NAS recommendations for the next phase. The staff's next step will be to proceed with the NAS-recommended approach to determine the feasibility of the Phase 1 methods through pilot studies at seven sites recommended by the NAS committee: [six nuclear power plant sites], and Nuclear Fuel Services in Tennessee.

Nitric acid leak at NFS Erwin nuclear fuel plant
The nitric acid leak at Nuclear Fuel Services on Monday (Jan. 9) may have totaled 800 gallons, a Tennessee Department of Environment & Conservation (TDEC) official said Tuesday (Jan. 10).
According to the TDEC spokeswoman Meg Lockhart, the initial report on the accident that was received by the state was "that approximately 800 gallons spilled. However, there was also water in the containment area, so we cannot determine exactly how much."
The Nuclear Regulatory Commission (NRC) report on Tuesday said that NFS reported to the regulatory agency that "approximately 300 gallons of nitric acid had spilled."
(The Greeneville Sun Jan. 11, 2012)
At approximately 12 p.m. today (Jan. 9), a nitric acid leak occurred in an outdoor bulk chemical storage area, according to a press release from Nuclear Fuel Services.
The nitric acid was contained by a dike designed for that purpose. Nitric acid may mix with water to cause fumes that can be hazardous.

Residents file lawsuit against NFS Erwin nuclear fuel plant
Attorneys from three states filed a class action lawsuit today (June 13) against Erwin's Nuclear Fuel Services, claiming emissions from NFS are to blame for high rates of cancer. The attorneys are fighting for their clients to get compensation for personal injury and property damage.
"No one wants to face the truth here and the truth is, I have highly enriched uranium on my property and I am 21 river miles downstream," says Park Overall who's one of the main advocates of the lawsuit against Nuclear Fuel Services. "I began to hear about all this cancer here, and we started to look into it. These chemicals and radioactive isotopes are related to particular cancers that we have too much of in the area."
Overall says Monday's filing of the class action lawsuit is the biggest step so far for the Erwin Citizens Awareness Network (ECAN). ECAN is a group that's researched NFS's emissions dating back to 1954.

Adkins, et al. v. W.R. Grace & Company, No. 2:11-CV-00173 (E.D. Tenn.)
Judge dismisses suit filed by residents against NFS Erwin nuclear fuel plant:
A federal judge last week dismissed a class-action lawsuit filed last year against Nuclear Fuel Services and its parent company that alleged "repeated releases of hazardous and radioactive substances" at the Erwin facility had led to injuries, property damage and emotional distress.
On Dec. 21, U.S. District Judge J. Ronnie Greer ordered that NFS' motion to dismiss the plaintiffs' claims be granted. It was also ordered that the plaintiffs’ motion to amend the original complaint be denied.
The lawsuit was filed in U.S. District Court in Greeneville in June 2011. In the original 40-page complaint, 13 of the 19 plaintiffs, including one former NFS employee, alleged they had developed various forms of cancer because of hazardous releases at the nearly 60-year-old facility. Two of the plaintiffs alleged the cancer deaths of relatives were caused by materials released from NFS. According to court documents, the number of plaintiffs increased to more than 140 individuals and organizations over the course of the case.

NRC issues Confirmatory Order to NFS Erwin nuclear fuel plant
The Nuclear Regulatory Commission has issued a Confirmatory Order to Nuclear Fuel Services, a nuclear fuel processing facility in Erwin, Tenn., which has agreed to a series of corrective actions related to the company's failure to provide the NRC with complete and accurate inspection information.
The order stems from a settlement achieved under the NRC's Alternative Dispute Resolution process, which was initiated at the request of NFS to address violations linked to fire damper inspections. On July 20, the NRC notified NFS that an agency investigation had substantiated that a former NFS Industrial Safety Specialist had on two occasions willfully provided the NRC with incomplete and inaccurate information about the inspections.

Study finds enriched uranium in river near NFS Erwin nuclear fuel plant
A new study out Thursday (Nov. 11) shows the troubled Nuclear Fuel Services plant in Erwin is apparently discharging enriched uranium into the Nolichucky River.
The Sierra Club and local activists gathered water, soil and shellfish, some as far as 45 river miles downriver from the nuclear fuel plant.
The scientist who analyzed the samples said the type of uranium seen in them is not the kind that is found in nature, and the only plausible interpretation is that the elements came from the processes at NFS.

Pressures may be too high in some uranium hexafluoride storage cylinders at the Nuclear Fuel Services, Inc. plant in Erwin
Pressures may be too high in some uranium hexafluoride (UF6) storage cylinders at the Nuclear Fuel Services, Inc. plant in Erwin, Erwin-based NFS has reported to the Nuclear Regulatory Commission.
That, according to a Jan. 20 "event notification report" posted on a Nuclear Regulatory Commission (NRC) Web site, apparently could pose a fire hazard and the company is taking precautions as a result.
But NRC Spokesman Joey Ledford said the problem is not believed to pose an immediate hazard to either workers or the public.
Ledford noted that NFS officials discovered the apparent pressure problem while making calculations as part of an investigation related to a Nov. 14 fire at the NFS plant.
He said there are "several hundred" of the cylinders that are about seven inches in length, or "about test-tube size." In addition, he said, there are five larger UF6 storage cylinders that are about a foot tall.
Ledford noted that 40 of the cylinders are "potentially at risk" from the pressure problem.
Ledford noted the NRC also is continuing an investigation into the Nov. 14 incident at the NFS plant and noted that it is "too early" to draw any conclusions into whether it was related to the suspected cylinder-pressure situation.
He also said some of the UF6 cylinders date to the 1950s and that most have been stored at the NFS plant for a number of years.

NFS to temporarily shut down most operations at Erwin nuclear fuel plant during safety changes after incidents
Nuclear Fuel Services in Erwin is suspending most of its production to deal with safety changes that are being implemented in cooperation with the Nuclear Regulatory Commission in the wake of several safety-related incidents.
NRC spokesman Joey Ledford said this morning the agency has had an "augmented inspection team" at NFS for several weeks. Ledford also said the NRC will issue a "confirmatory action letter" next week outlining what NFS will need to do to restart the idled operations.

Fire in UF6 cylinder sublimation station at NFS Erwin nuclear fuel plant
"On Saturday November 14, 2009 at approximately 0730 there was a heated high pressure release from the 5A/5B UF6 cylinder in the CDL facility Sublimation Station 3. At the time of the upset, the operators were in the process of preparing the cylinder for sublimation. They had just satisfactorily performed the valve leak checks (SOP 409 Section 56 step 5.3) and were performing the cylinder pressure test (SOP 409 Section 56 step 5.4). The cylinder was not being heated. The upset occurred when the cylinder valve was opened (step 5.4.7) to vent the cylinder to column 1D01. The release ruptured the connective teflon tubing that was enclosed in braided stainless steel. When flame was observed the operator actuated the CO2 release valve and extinguished the flame. The subsequent damage appears to be limited to: 1). Braided teflon tubing, 2). Singed area on lexan cover of the enclosure, 3). Possible leak on the inlet and outlet side of the eductor."
"No actual exposures occurred to the workers, the public, and environment. Potential UF6 exposure to workers. However, no loss of containment occurred."

The U. S. Nuclear Regulatory Commission (NRC) staff is considering
a request to amend Materials License SNM-124, issued to Nuclear Fuel
Services, Inc. (NFS), to authorize an increase in the
possession limit of high-enriched uranium (HEU). The NRC has prepared an Environmental Assessment (EA) in support of this action. Based upon the
EA, the NRC has concluded that a Finding of No Significant Impact
(FONSI) is appropriate and, therefore, an Environmental Impact
Statement (EIS) will not be prepared.
The NFS facility in Erwin, Tennessee is authorized, under License
SNM-124, to manufacture high-enriched nuclear reactor fuel. In
addition, NFS is authorized to blend HEU with natural uranium and
manufacture low-enriched nuclear reactor fuel. License SNM-124 limits
the amount of HEU that NFS may possess for these operations. On May 15,
2007, NFS requested a license amendment to increase its possession
limit of HEU.

NRC reveals spill of high-enriched uranium at NFS Erwin nuclear fuel plant
In its Report to Congress on Abnormal Occurrences - Fiscal Year 2006, NRC reported a spill of high-enriched uranium that had occured at the NFS Erwin nuclear fuel plant on March 6, 2006:
"In a facility authorized to
process high-enriched uranium (HEU), a transfer of HEU solution through
a transfer line resulted in a portion of the HEU solution,
approximately 35 liters, leaking into a glovebox where criticality was
possible and subsequently to the floor where criticality was also
possible because of the presence of an elevator pit." [...]
"In different circumstances, the total volume of the
transfer would have been more than enough for criticality to be
possible in the filter glovebox or the elevator pit. If a criticality
accident had occurred in the filter glovebox or the elevator pit, it is
likely that at least one worker would have received an exposure high
enough to cause acute health effects or death."

ATSDR releases draft Public Health Assessment finding No Apparent
Public Health Hazard
ATSDR has evaluated the releases of volatile organic compounds to the environment
surrounding the Nuclear Fuel Services, Inc. facility in Erwin, Tennessee. The releases of these materials may have occurred in the 1950s, 1960s, and 1970s; there was little or no monitoring of the environmental media at that time.
CERCLA legislation directing ATSDR activities excluded the evaluation of the radioactive materials released from this site.
- Past Conditions: for lack of data, ATSDR considers the site an Indeterminant Public Health Hazard.
- Current and Future Conditions: ATSDR ranks this site as No Apparent
Public Health Hazard, as there are no completed exposure pathways
existing whereby the groundwater would be used as a source of public water.
ATSDR concludes that although some
exposure might be occurring as a result of site conditions via the atmospheric
exposure pathways, exposures are not at levels likely to cause adverse health
effects and thus the site does not pose a public health hazard.

Two uranium fuel plants in Lynchburg, Virginia, and Erwin, Tennessee, must immediately adopt stricter anti-terrorist measures such as more guards, vehicle barriers and patrols, the Nuclear Regulatory Commission said on Aug. 22, 2002.
The plants, owned by BWX Technologies Inc. and Nuclear Fuel Services, take enriched uranium and make it into fuel for nuclear reactors.
The NRC said it ordered the two plants to adopt similar measures already put in place by U.S. nuclear power plants as a precaution after the Sept. 11 attacks. (Reuters Aug. 22, 2002)

Judge refuses to dismiss lawsuit against NFS
A federal judge has refused to dismiss a lawsuit filed earlier this year by two Erwin companies that claim Nuclear Fuel Services contaminated their property.
Impact Plastics Inc., Preston Tool and Mold, and Gerald O'Conner Jr. filed a lawsuit May 31, 2002, in U.S. District Court in Greeneville claiming NFS has allowed hazardous substances - such as uranium, thorium and plutonium - to migrate from its facility to their property.
The plaintiffs cite environmental reports that show that NFS has allowed the contaminants to migrate and impact upon the groundwater beneath their property, including the Nolichucky River. According to the lawsuit, the plaintiffs claim NFS has failed to abate the movement of these substances even though they have urged the company to do so. NFS filed a motion on Aug. 9, 2002, asking for the lawsuit to be dismissed. On Dec. 11, 2002, U.S. District Judge Thomas Hull denied the motion to dismiss.

NRC issues Notice of License Amendment Request of Nuclear Fuel Services, Inc., Erwin, TN, and Opportunity To Request a Hearing on CD Line Facility (HEU deconversion) project
The Nuclear Regulatory Commission (NRC) has received, by letter dated August 31, 2007, a license amendment application from Nuclear Fuel Services, Inc., requesting authority to process uranium hexafluoride (UF6) in a new Commercial Development (CD) line at its facility site located in Erwin, Tennessee. Specifically, the amendment provides authorization to convert high-enriched uranium (HEU) in the form of UF6 into another chemical form (oxide or nitrate), which can be processed in the existing facility.
The purpose of CD line process operations is to convert Department of Energy (DOE) highly-enriched uranium (HEU) in the form of UF6 to either uranium oxide form (U3O8), or to uranyl nitrate solution for subsequent purification and downblending in the adjacent BLEU Preparation Facility (BPF) (Building 333). The final form depends on the enrichment.
A request for a hearing must be filed by February 29, 2008.

NRC proposes imposition of $140,000 penalty for violations leading to an accident in the NFS Erwin BLEU fuel plant
On Sep. 2, 2010, NRC issued a Notice of Violation to NFS and proposed the imposition of a penalty of $140,000 for violations leading to an accident in a bowl cleaning station of the uranium aluminum process in the Blended Low-Enriched Uranium Preparation Facility on October 13, 2009.
On October 12, 2009, NFS finalized procedure changes to allow chemical processing of high enriched uranium scrap material in the centrifuge bowl cleaning stations. On October 13, 2009, upon addition of nitric acid into the bowl cleaning station, the solution exhibited an unexpectedly high rate of reaction. The operator shut down the station recirculation pump and shut off the heaters. However, the reaction continued producing an excessive quantity of nitrogen compound gases (NOx). These gases triggered NOx detectors at the air gap of the nitric acid knockout column, which prompted an evacuation of the building. The heated gases deformed a section of the wet off-gas piping system for the bowl cleaning station and the nitric acid knockout column.

NFS receives first of three license amendments required for BLEU project
On July 7, 2003, the U.S. Nuclear Regulatory Commission (NRC) has approved the first of three license amendments Nuclear Fuel Services Inc. in Erwin will need to recycle weapons-grade uranium into commercial reactor fuel for the Tennessee Valley Authority.
Under the first BLEU license amendment, NFS can begin receiving low-enriched uranyle nitrate solution from DOE's Savannah River Site in South Carolina.
The agency approved the amendment even though a public hearing request from interested groups is pending with the independent Atomic Safety and Licensing Board.
A second license amendment, requested in October 2002, will allow NFS to begin operating a new facility to convert the material into low-enriched uranium oxide.
The third license amendment will be for a facility to convert the material into fuel for commercial nuclear reactors. NFS officials said they expect to apply for that third license amendment in the third or fourth quarter of 2003.

On September 11, 2002, an NRC Atomic Safety and Licensing Board (ASLBP) issued a Memorandum and Order "Raising Questions Regarding Completeness of [the] Federal Register Notice" dated July 9, 2002 (see below). The Nuclear Regulatory Commission has until Sept. 19, 2002 to answer the questions.
On September 19, 2002, "the [NRC] Staff recognizes that the July 9, 2002 Federal Register Notice was inadequate in that it failed to properly notice the opportunity for a hearing. In order to remedy this defect, the Staff will publish a revised notice to properly notice both the license amendment application and the opportunity for hearing."
Citizens File Objection To Nuclear Fuel Services' Proposed Expansion Plans
A Greeneville attorney has filed documents with the U.S. Nuclear Regulatory Commission (NRC) on behalf of 15 Northeast Tennessee residents objecting to an amendment of an Nuclear Fuel Services Inc.'s (NFS) "special nuclear material license." NFS seeks to build additional buildings and begin a new production process in which highly enriched uranium will be "down-blended" to produce low-enriched uranium fuel for Tennessee Valley Authority nuclear reactors.

NRC issues Environmental Assessment for NFS' Blended Low-Enrichment Uranium (BLEU) project
An “environmental assessment” issued by the Nuclear Regulatory Commission (NRC) on July 9, 2002, indicates that a proposed new operation at Erwin-based Nuclear Fuel Services, Inc., will result in the release of “small amounts” of both chemicals and radioactive materials to the atmosphere.
The environmental assessment indicates that the NRC expects “no significant impact,” from approval of a request for amendments to Nuclear Fuel Services’s “materials license” to allow construction and operation of a uranyl nitrate storage building on the NFS site in Erwin, and to increase the amount of Uranium 235 that can be stored there.
The requested license amendments, according to the environmental assessment, are part of preparations by NFS eventually to implement a Blended Low-Enrichment Uranium (BLEU) project.
NFS had announced earlier plans to turn 33 metric tons of bomb-grade uranium into fuel for Tennessee Valley Authority (TVA) reactors at the Browns Ferry Nuclear Plant in Athens, Ala.
The BLEU Project is part of a Department of Energy program to reduce stockpiles of surplus high-enriched uranium through reuse of low-enriched uranium, thus converting weapons grade material to a form unsuitable for nuclear weapons and addressing a nuclear proliferation concern.
Because the BLEU Project supports the production of nuclear generated electric power for public use, NFS will have to comply with a more stringent public dose constraint. To address the change, NFS has submitted revised dose assessment methods for NRC review.
