  4. 4. Center for Ene1·gy and Environmental Research CENTER FOR ENERGY AND ENVIRONMENTAL RESEARCH 1.0 SITE SUMMARY 1.1 Site Description and Mission The Center for Energy and Environmental Research (CEER), located in the Commonwealth of Puerto Rico, was established in 1957 as the Puerto Rico Nuclear Center. It consists of four distinct sites: Mayaguez, El Verde Research Station, and Rio Piedras, operated by the University of Puerto Rico; as well as the Boiling Nuclear Superheat Research Reactor operated by the Puerto Rico Electric Power Authority. These areas were operated under contract to the U.S. Department of Energy (DOE) and its predecessors. The four sites total approximately 72 hectares (181 acres). Each site's specific location and mission is described below: LONG-TERM STEWARDSHIP HIGHLIGHTS Major Long-Term Stewardship Activities- surveillance; inspections Total Site Area- 72 hectares (181 acres) Estimated Volume of Residual Contaminants- facilities unknown Long-Term Stewardship Start-End Years- 1970-in perpetuity Average Annual Long-Term Stewardship Cost FY 2000-2006 • $25,000 Landlord- U.S. Department of Energy and Puerto Rico Electric Power Authority The Mayaguez Site is located in western Puerto Rico, approximately two kilometers (one mile) east of Mayaguez Bay. This site spans roughly ten hectares (20 acres) and is situated adjacent to the University of Puerto Rico College of Agriculture and Mechanical Arts and the U.S. Department of Agriculture Experiment Station, northeast of the Mayaguez city limits. The Mayaguez Site is a multiple structure facility that housed the marine studies program, the original research reactor, and associated laboratories. In 1976, reactor research activities at the site concluded with the closure of the TRIGA Research Reactor and L-77 Training Reactor. Consequently, the facility mission broadened to include non-nuclear energy research and technology development. TheEl Verde Research Station encompasses approximately 63 hectares ( 156 acres), and is located in the Luquillo Forest approximately 23 kilometers (14 miles) southeast of San Juan in northeastern Puerto Rico. The El Verde site was an experimental research station that supported a terrestrial ecology program between 1964 and 1976. This site performed radiological tests on the trees and vegetation in a section of rainforest to study mineral cycling and metabolism. The site was transferred to the U.S. Department of Agriculture in 1997. The ongoing mission of the site is non-radiological terrestrial ecology research. The Rio Piedras Site is located approximately three kilometers (two miles) south of San Juan and consists of a Biomedical facility. A former underground diesel fuel storage tank was removed in 1994. The primary focus of work at the Rio Piedras Site was nuclear medicine research. In 1982, the site was transferred from DOE to the University of Puerto Rico by means of a Quit Claim Deed. • The Boiling Nuclear Superheat Research Reactor, which encompasses two hectares (five acres), is located in Rincon, approximately 21 kilometers ( 13 miles) northwest ofMayaguez. The Boiling Nuclear Superheat Research Reactor operated as a research reactor between 1962 and 1967. The facility was decommissioned by 1970, and the reactor vessel and other components were entombed in place. Puerto Rico Electric Power Authority owns the land; however, DOE is responsible for the facility. Puerto Rico 3

In October 1981, the L-77 solution fuel core was removed and shipped to DOE's Y-12 Plant in Oak Ridge, Tennessee. Decommissioning of the reactor, remedial decontamination, and restoration cleanup of the facility was completed prior to 1997. In addition, soils contaminated with polychlorinated biphenyls (PCBs), underground storage tanks containing fuel oil, unknown gas cylinders, hot cells (glass windows), asbestos, and miscellaneous laboratory chemicals were removed. The Mayaguez Site will be transferred to the U.S. Department of Agriculture by 2000. • DOE has removed contaminated material and has restored the trail in the El Verde Research Station. • At the Rio Piedras Site, underground storage tanks containing fuel oil were removed and diesel-contaminated soil cleanup was completed. An asbestos survey and sampling of the Biomedical Building at the site have been completed. Puerto Rico 4
  6. 6. Center for Energy and Environmental Resear·ch DOE has removed and disposed of non-contaminated materials at the Boiling Nuclear Superheat Research Reactor facility. Radioactive fuel was disposed of in the continental United States. The Boiling Nuclear Superheat Research Reactor has been entombed and all of the underground storage tanks containing fuel oil have been removed from the site. The beta and gamma activity of the entombed material was 53,259 curies, when the measurement was taken in 1968. 2.0 SITE-WIDE LONG-TERM STEWARDSHIP 2.1 Long-Term Stewardship Activities Both the El Verde Research Station and the Rio Piedras Site have been transferred to the U.S. Department of Agriculture and University of Puerto Rico, respectively, and consequently, DOE does not anticipate any longterm stewardship responsibilities. Assuming the Mayaguez Site is transferred to the U.S. Department of Agriculture, DOE will not be responsible for long-term stewardship activities at the site. DOE is responsible for long-term stewardship activities at the Boiling Nuclear Superheat Research Reactor. Long-term stewardship activities include surveillance and inspection of the facility. Long-term stewardship activities are expected to continue in perpetuity. Access to the Boiling Nuclear Superheat Research Reactor is restricted by a locked gate, fence, and security guard. These access restrictions are maintained and repaired, as needed, by the Puerto Rico STAKEHOLDER INVOLVEMENT Electric Power Authority. Institutional controls are also enforced by the Puerto Rico Electric Power Community interaction regarding the Boiling Nuclear Authority. Because of entombed radioactive Superheat Research Reactor facility has involved many materials left in place, it is assumed that this area groups, including La Liga Ecologica Puertorriquena will remain controlled access. DOE will continue and Frente Unido Ambiental. Copies of annual to survey and inspect the Boiling Nuclear inspection reports for the site are distributed to the Superheat Research Reactor facility to ensure public. In addition, public meetings are held to discuss protection of human health and the environment. survey information and future use of the facility. DOE maintains and updates the specific records and reports required to document long-term stewardship activities at the Boiling Nuclear Superheat Reactor Research site. Site records are kept in permanent storage at the DOE Oak Ridge Office and historic operation records are maintained at the site. The types of records maintained include site characterization data, remedial action design information, the site completion report, long-term monitoring plans, annual inspection reports, and current and historic monitoring data. Long-term stewardship costs for the Boiling Nuclear Superheat Research Reactor are based on historic costs incurred while conducting annual surveillance and inspection activities. These costs are approximately $25,000 per year. 2.2 Assumptions and Uncertainties A CERCLA 120(h)(4) report has been requested by the U.S. Department of Agriculture prior to transferring the Mayaguez Site. The site will be transferred directly to the University of Puerto Rico under provision 16l(g) of the Atomic Energy Act. The transfer will be completed by the end of December 2000. The Boiling Nuclear Superheat Reactor Research site is anticipated to be transferred to DOE's Grand Junction Puerto Rico 5

National Defense Authorization Act (NDAA) Long-Term Steardship Report Office for long-term surveillance and maintenance by the end of FY 2001. 3.0 FUTURE USES Because of entombed radioactive materials left in place, it is assumed that the Boiling Nuclear Superheat Reactor Research area will remain under controlled access. However, the Puerto Rico Electric Power Authority is developing a museum in the reactor building, in which only certain areas will be open to the public. All future-use decisions regarding Mayaguez, El Verde Research Station, and Rio Piedras sites are the responsibility of the landlord organizations.
