the end of the Cold War, production of nuclear materials for weapons use ceased. Post-Cold War Roger D. Wensil, a pipe-fitter, worked for the B.F. Shaw Co., a subcontractor at Savannah River. In 1985, Wensil was dismissed as a whistleblower, after he complained of safety violations and illegal drug use among construction workers building a sensitive nuclear waste-handling facility at the plant. In 1992, the U.S. Congress enacted "nuclear weapons whistleblower protection". In 1992, the cooling tower was connected to the K Reactor, and the reactor operated briefly for the last time. The Secretary of Energy announced the phase-out of all uranium processing. Non-radioactive operations began at the Replacement Tritium Facility and the Defense Waste Processing Facility (DWPF). K Reactor was placed in cold standby condition in 1993. Non-radioactive test runs of the Defense Waste Processing Facility began. Construction began on the Consolidated Incineration Facility. Tritium introduced into the Replacement Tritium Facility and radioactive operations began. The Workforce Transition and Community Assistance was started. In 1994, the Savannah River Site Citizens Advisory Board was established. The Replacement Tritium Facility saw its startup. In 1996, DWPF introduced radioactive material into the vitrification process. K Reactor was shut down. F Canyon was restarted and began stabilizing nuclear materials. In 1997, the first high-level radioactive waste tanks were closed, numbers 17 and 20. The Cold War Historic Preservation Program was begun. In 2000, the K-Reactor building was converted to the K Area Materials Storage Facility. The Savannah River Site was selected as the location of three new plutonium facilities for: a MOX fuel fabrication; pit disassembly and conversion; and plutonium immobilization. WSRC earned the DOE's top safety performance honor of Star Status. Thousands of shipments of transuranic waste were contained and sent by truck and by rail to the DOE's Waste Isolation Pilot Plant (WIPP) Project in New Mexico, with the first shipments beginning in 2001. DWPF completed production of four million pounds of environmentally acceptable classified waste. In 2002, the F Canyon and FB Line facilities completed their last production run. The Savannah River Technology Center participated in a study of using a nuclear power reactor to produce hydrogen from water. Scientists reported finding a new species of radiation-resistant extremophiles inside one of the tanks. It was named Kineococcus radiotolerans. In January 2003, Westinghouse Savannah River Co. completed transferring the last of F Canyon's radioactive material to H Tank Farm. DWPF began
