Piqua Organic Moderated Reactor

Piqua Reactor

Piqua is a DOE facility for 1963-February 28, 1969 so workers are eligible to file Part B claims.

Piqua has a Special Exposure Cohort which covers all workers with specific cancers and at least 250 days of employment for May 2, 1966 through February 28, 1969.

From 1963 to 1966, the Piqua Nuclear Power Facility was operated as a demonstration project by the City of Piqua. The facility contained a 45.5-megawatt (thermal) organically cooled and moderated reactor. In 1966, the AEC discontinued facility operations and terminated its contract with the city. The AEC dismantled and decommissioned the reactor between 1967 and 1969. The reactor fuel coolant and most of the radioactive materials were removed from the site.    

The Piqua nuclear power facility was a demonstration plant, located in Piqua, Ohio. It became operational in 1963 and closed in 1966, with on-site disposal completed in 1969. The reactor was organically cooled and moderated, and was designed to produce 45.5 megawatts. Problems with the organic cooling system led to the early plant closure. The irradiated nuclear fuel, selected reactor core components and other radioactive materials were removed to a federal nuclear installation. The organic coolant and moderator was disposed of by burning. The reactor vessel, thermal shield, grid plates, and support barrels remained in place. The vessel penetrations were seal-welded, the vessel was filled with sand, and the enclosure penetrations were plugged. The enclosure was sealed with a waterproof barrier and a concrete cover. Contaminated piping and equipment was either decontaminated or removed from the reactor building, which was converted into a warehouse. An estimated 260 000 Ci ( 9.6 103 Tbq) were sealed within the enclosure at the time of onsite disposal. Analyses predicted that the contained radioactivity would decay to unrestricted release levels after about 120 years. No monitoring systems were installed. The only current activities at the Piqua Nuclear Power Facility are the annual surveillance and monitoring conducted by the Environmental Management program. The minimal landlord activities associated with this facility are the responsibility of the City of Piqua.
