In a dissenting statement (made public on Feb. 22, 2002), unprecedented in the history of the commission and of its predecessor, the Atomic Energy Control Board, Commission Member Dr. C. R. Barnes external link disagreed with the 5-year duration of the license term (rather than the 3-year terms issued earlier):

"Commission Member Dr. C. R. Barnes concurred with the other Members that the licensee meets the requirements of section 24(4) of the NSCA and therefore that a licence should be issued.
Dr. Barnes, however, disagreed with the majority view on the duration of the licence term. In Dr. Barnes' view, a maximum licence term of three years should be approved. Dr. Barnes held that a five-year licence should be reserved for facilities where the effects have been demonstrated to be well characterized and where public concerns about health and safety are not high. Dr. Barnes found that a five-year licence in this case would not adequately address the significant remaining concerns of the public about the health effects of the facility in combination with the past uranium contamination in the community. Furthermore, Dr. Barnes was also concerned about the current lack of environmental effects monitoring in the vicinity of the facility. Dr. Barnes is of the view that bringing the matter of the licence renewal before the Commission in three years time, as opposed to a status report, will have a greater influence on ensuring the licensee maintains close attention to the design and implementation of the environmental effects monitoring program and the need to continue to address the significant remaining concerns of the people potentially affected."

Impacts of Port Hope fuel facility on environment and residents' health

During the 1940's to 1960's, the Port Hope fuel facility caused massive releases of contaminants into the enviroment. In the Mill Street/ Madison Street area located south-east to the facility, the Ontario MOE found a uranium concentration of 135 ppm in 1986. The concentration had decreased to 40 ppm in 1997 (AECB BMD 00-29, Feb. 1, 2000).

The current uranium deposition rate is being monitored at 5 test plots, at two of them by Ontario MOE and at three by Cameco. At the Cameco soil test plots, a maximum increase in soil uranium concentration of 0.58 ppm per year was observed for the first year 1998. At MOE's Town Hall plot, the uranium concentration in soil dropped from initially 0.85 ppm to 0.56 ppm in 1997 and 0.58 ppm in 1998. At MOE's Marina plot, the uranium concentration increased from initially 0.85 ppm to 1.78 ppm in 1997 and further to 3.93 ppm in 1998. Normal background levels for uranium in soil in Ontario are up to 2 ppm. (AECB BMD 99-123, Sep. 21, 1999)
Respirable uranium particulate in air is being monitored at three locations around the Port Hope fuel facility since 1998. The highest average monitored at one of these stations was 0.0074 µg/m3 (AECB BMD 99-123, Sep. 21, 1999). The corresponding radiation dose from inhalation can be calculated at 0.013 mSv/a.

At the request of the Port Hope Community Health Concerns Committee (PHCHCC), AECB has ordered a cancer incidence study in Port Hope from Health Canada.
PNCHCC has requested further studies by independent researchers. (AECB BMD 00-30, Jan. 31, 2000).

The Health Canada study was released on August 22, 2000. It has found that the overall cancer rates in the town of Port Hope, Ontario are comparable to rates throughout the Province of Ontario.

(view CNSC News Release August 22, 2000)

On June 17, 2002, CNSC released Health Canada's Port Hope mortality report (Cancer and General Mortality in Port Hope, 1956–1997):

"The cancer findings are, on the whole, consistent with the earlier cancer incidence report and previous Port Hope studies. The patterns of cancer mortality in Port Hope are comparable to the province of Ontario as a whole. This pattern is consistent with existing knowledge of doseresponse relationships of radiation risk that an observable excess of cancer wound not be expected because the cumulative doses in Port Hope were low (Tracey 1995, ICRP-60, Boice 1996)."
(Information from Canadian Nuclear Safety Commission Staff Regarding Cancer and General Mortality in Port Hope, 1956–1997, CMD 02-M47, June 10, 2002)

Cameco Port Hope conversion plant cooling water discharge fails to pass toxicity test due to higher-than normal concentration of potable water (!)

Analysis of cooling water discharge on Oct. 7, 2014, indicated that the north discharge did not meet the toxicity requirement for Daphnia magna (water fleas). The testing on rainbow trout passed the toxicity requirement.
The toxicity failure occurred during a period when the facility was experiencing issues with pumping of cooling water from the harbour. Potable water (municipal drinking water) flow to equipment in the UF6 plant continued. Due to the higher-than normal concentration of potable water relative to harbour water in the discharge, elevated levels of chlorine residual were found in the samples. Chlorine in municipal drinking water is toxic to Daphnia magna. Additional water samples have been taken and the results are pending. (Cameco Oct. 10 2014)

 

Cameco Port Hope conversion plant discharges cooling water containing elevated levels of uranium and fluoride to harbour

A leak within a heat exchanger in the UF6 plant resulted in cooling water coming into contact with process water, which was then discharged to the harbour. This situation appears to have begun on Friday, September 26 and was discovered on Monday, September 29. Initial sampling indicates that there was no significant impact on water quality in the harbour. (Cameco Sep. 30, 2014)

Cameco Port Hope UF6 plant shut down after loss-of-control incident

CNSC staff received notification from Cameco on January 29th, 2014, about an incident which required Cameco to perform a manual shutdown to a critical process for uranium hexafluoride (UF6) conversion. This manual shutdown was necessary due to a potentially unsafe valve configuration required to maintain a safe working condition within the facility.
On February 10, 2014, the CNSC permitted Cameco to restart the facility.

String of incidents prompts investigation at Cameco Port Hope conversion plant

There have been several incidents of "exceedances" and spills at Cameco over the last few months and Rebecca Peters, superintendent, compliance and licensing for Cameco's Port Hope conversion facility, says the company is looking into them. (Northumberland Today Oct. 14, 2009)

Cameco resumes UF6 production in Port Hope

On May 19, 2009, Cameco Corporation announced that it is preparing to resume uranium hexafluoride (UF6) production at its Port Hope conversion facility. Cameco has signed a new contract with its historic supplier of hydrofluoric acid (HF). UF6 production is expected to resume early in the third quarter of 2009.
On June 17, 2009, Cameco Corporation announced that it has resumed production of uranium hexafluoride (UF6) at its Port Hope, Ontario conversion facility.

Cameco temporarily suspends UF6 production in Port Hope

On Nov. 28, 2008, Cameco Corporation announced it is suspending uranium hexafluoride (UF6) production at the company's Port Hope plant. As previously announced, a contract dispute between Cameco and its sole supplier of hydrofluoric acid (HF) has resulted in unreliable and expensive deliveries of this material necessary for the production of UF6. The dispute remains unresolved and Cameco has exhausted the inventory of HF it had purchased on a spot basis. (Cameco Nov. 28, 2008)

Cameco plans temporary shutdown of Port Hope conversion plant for poor economics

Cameco anticipates the UF6 (uranium hexafluoride) building is expected to close in December 2008 until at least mid-summer 2009. The closure is blamed on the high cost of hydrofluoric acid (HF) and plummeting sales. (Northumberland Today Nov. 13, 2008)

 

Cameco suspends operation of Port Hope conversion plant, after contaminants found in subsoil

On July 20, 2007, Cameco Corporation reported that during a construction project it discovered uranium and evidence of other production-associated chemicals in the soil beneath its Port Hope uranium hexafluoride (UF6) conversion plant. The affected area "appears to be" within, and near, the perimeter walls of the UF6 plant based on the preliminary information available at this time. The chemicals are in a contained area so public health and worker safety are not affected.
Due to the nature of soil at the plant, Cameco expects the ground water flow rate, with the chemicals, to average approximately 40 to 60 metres each year. The perimeter of the plant is about 70 metres from the edge of the property. Cameco has monitoring wells around the property to detect chemicals in the area. These wells are checked quarterly and reported to the regulator annually. The last scheduled samples were taken in April and did not indicate potential issues. Cameco has arranged for additional samples to be taken.
Cameco has suspended operations at the UF6 conversion plant, and full production of UF6 will likely be suspended for a minimum of two months until Cameco has determined the source of the chemicals and developed appropriate plans.

On Oct. 3, 2007, Cameco reported that groundwater test results from a new monitoring well indicate slightly elevated levels of uranium and arsenic at a location eight metres inside the fenceline south of the UF6 production building. This is the first indication that contamination may be present beyond the property line.

On Oct. 15, 2007, Cameco released a root cause report on the incident. The report identified the following causal factors:

  1. Some 'floors, sumps & trenches' are not designed to resist a corrosive environment;
  2. Liquid entering 'floors, sumps & trenches' is frequently corrosive and attacks the 'floors, sumps & trenches';
  3. Uranium and chemicals frequently enter the 'floors, sumps & trenches';
  4. Liquid and sludge remain in the 'floors, sumps & trenches' for sustained periods of time;
  5. Some 'floors, sumps & trenches' deteriorated over time and began to leak; and
  6. The monitoring system does not detect deterioration of and/or leakage from the 'floors, sumps & trenches'.

On Jan. 28, 2008, Cameco Corporation reported it has received regulatory approval to begin repairing and upgrading the Port Hope uranium hexafluoride (UF6) conversion plant following the discovery of soil contamination beneath the facility. UF6 plant operations have been suspended since the discovery in July 2007. Cameco has set a target of resuming UF6 production in the third quarter of 2008 at the earliest.
The estimate for the cleanup of the contaminated soil at Port Hope has been increased to C$15 to C$20 million from the C$3 million previously recorded due to an increase in the scope of work required to remediate the contaminated areas. In addition, Cameco expects to spend C$20 to C$25 million on plant improvements.

The leak from Cameco's uranium hexafluoride (UF6) plant has reached the harbour, federal nuclear regulators were told on May 14, 2008. (Northumberland News May 15, 2008)

On Sep. 16, 2008, Cameco announced that CNSC staff has accepted Cameco's plans to restart UF6 production. The restart is expected to happen within the next several days.

Cameco expects total remediation costs to be $50 to $55 million of which approximately $20 million (including $17 million incurred in 2007) will be expensed and the remainder capitalized. Cameco said the money was used to investigate the possibility that uranium, arsenic and fluorides may have seeped into Lake Ontario, rehabilitate the plant and install a system of wells that collect impacted groundwater. The company also made a number of improvements inside the plant, including replacement of large sections of the ground floor and application of chemical-resistant coatings to all floors, as well as removal of some contaminated soil from under the building. (Canadian Press 17 Sep 2008)

On September 30, 2008, Cameco Corporation announced that it has resumed production of uranium hexafluoride (UF6) at its Port Hope conversion facility. Cameco voluntarily halted production in July 2007 and indicated recently that the company had resolved the issues that led to the presence of uranium and other production-related chemicals beneath the plant.

Cameco Port Hope UO2 plant (Ontario)

Cameco Port Hope UO2 plant shut down after elevated uranium emissions

On June 29, 2010, Cameco notified the Canadian Nuclear Safety Commission (CNSC), that it had potentially exceeded an Action Level for uranium emissions from its UO2 plant in Port Hope, Ontario. On June 30, 2010 Cameco voluntarily shut down the UO2 plant to conduct their investigation to determine potential sources of elevated uranium emissions.
On July 12, 2010, Cameco submitted its report on uranium emissions from its UO2 plant main stack. Based on the review of this report, the CNSC has determined that on June 29 the UO2 plant uranium emission rate was 7.21 gU/h (grams of uranium emissions per hour). Although this rate is well below the licensed limit of 150 gU/h, it is above the plant's Action Level of 7 gU/h.
The CNSC has asked that Cameco submit its final investigation report, including the causes of elevated uranium emissions and the corrective actions that will be taken to prevent reoccurrence of the June 29 incident.

Leak under UO2 plant contributes to contamination at Cameco's Port Hope conversion plant

A leak was found under the UO2 (uranium dioxide) plant during its shutdown that has been contributing to the historical and recent contamination of the soils at Cameco's Port Hope Conversion Facility, general manager Andy Thorne told Port Hope council last night. He said a yellow stain led to the discovery of the leak under the main sump near the eastern wall of the UO2 building and on Nov. 5, excavation took place to remove 17.5 cubic metres of contaminated soil.

Uranium waste solution from Port Hope fuel facility used as fertilizer

"In the production of UO2, an ammonium nitrate by-product solution is produced. The solution is treated to reduce uranium and radium to levels less than 10 mgU/L and 370 mBq/L respectively.

CNSC approves Environmental Assessment Screening Report for Port Granby waste management facility

Following a hearing held on August 17, 2009 in Ottawa, Ontario, the Canadian Nuclear Safety Commission (CNSC) announced today its decision that the Low-Level Radioactive Waste Management Office's (LLRMWO) proposed project to construct and operate the Port Granby long-term low-level radioactive waste management facility in the municipality of Clarington is not likely to cause significant adverse environmental effects, taking into account mitigation measures identified in the Environmental Assessment Screening Report.
The Commission can therefore proceed, under the Nuclear Safety and Control Act, with its consideration of a licence application from the LLRWMO for the proposed project.
