Also Known As: Hanford Engineer Works (HEW), Richland
State: Washington
Location: Richland
Time Period: 1942-present
Facility Type: Department of Energy
 
Facility Description:
Hanford was established in 1942, as a major government-owned nuclear weapons production site, fabricating reactor fuel, operating nine nuclear material production reactors and building five major chemical separation plants, and producing plutonium for nuclear weapons.
 
Later operations also included nonmilitary applications of nuclear energy. In 1965, the laboratory functions performed at Hanford were separately identified as Pacific Northwest Laboratory (renamed Pacific Northwest National Laboratory in 1995) and were operated by Battelle Memorial Institute. This work took place on the premises of the Hanford site through the end of 2004. Beginning in 2005, Battelle also began operating a separate facility in Richland where some on these laboratory functions were performed.
 
Throughout the course of its operations, the potential for beryllium exposure existed at this site, due to beryllium use, residual contamination, and decontamination activities.

Note: This class was established from Petition 57
 
All employees of the Department of Energy, its predecessor agencies, and its contractors and subcontractors who worked at the Hanford site in Richland, Washington, from October 1, 1943 through June 30, 1972, for a number of work days aggregating at least 250 work days, occurring either solely under this employment or in combination with work days within the parameters established for one or more other classes of employees included in the Special Exposure Cohort.

Note: This class was established from Petition 152
 
All employees of the Department of Energy, its predecessor agencies, and their contractors and subcontractors who worked at the Hanford Engineer Works in Richland, Washington, from July 1, 1972, through December 31, 1983, for a number of work days aggregating at least 250 work days, occurring either solely under this employment or in combination with work days within the parameters established for one or more other classes of employees included in the Special Exposure Cohort.

Note: This class was established from Petition 201
 
The SEC now includes U.S. Department of Energy contractors and subcontractors who worked at the Hanford site from January 1, 1984 through December 31, 1990, for at least 250 days total, either solely under this employment, or in combination with work days within the parameters established for one or more other classes of employees included in the SEC.
 
The SEC excludes employees of the following Hanford contractors during the time periods specified below:

  • Battelle Memorial Institute, January 1, 1984 through December 31, 1990;
  • Rockwell Hanford Operations, January 1, 1984 through June 28, 1987;
  • Boeing Computer Services Richland, January 1, 1984 through June 28, 1987;
  • UNC Nuclear Industries, January 1, 1984 through June 28, 1987;
  • Westinghouse Hanford Company, January 1, 1984 through December 31, 1990; and
  • Hanford Environmental Health Foundation, January 1, 1984 through December 31, 1990.

 
History:
The Hanford Site in the state of Washington was created in January 1943 to produce plutonium as part of the Manhattan Project. The site was chosen because of its proximity to the Columbia River needed to cool nuclear reactors, rail accessibility, and the availability of hydroelectricity derived from dams along the Columbia River. Hundred of buildings were constructed on the site and eventually about 50,000 people lived there. By the mid-60’s the need for plutonium had decreased and eventually all eight single-purpose plutonium reactors were closed. In 1975 Hartford engaged in energy research until 1989 when the main mission became waste cleanup. No plutonium has been produced on site since that time.
 
Compensation:
As of 09/07/2015, the total compensation paid under Parts B and E of the EEOICPA, including medical compensation, for workers suffering from the effects of having worked at Hanford is $1,193,514,479.
