By this time, the ARC had met all Department ofDelense requirements for nuclear weapons production and had crested a huge arsenal ofnuclear weapons. Accordingly, Presidert Lyndon 8. Johnson decided to redace mucheer materiale production and presented it a9 a disarmament measure in ins 1964 Stare ofthe Union address. As a result, ever the newt seven years, the AEC shut down all but one of the Hantord production reactors. Because the Hanford ares was 2 one mdusiry town, the AECalso took stene to keep the area coonomically vieble by aiming io bring new industry and contractors into the area. It srouned these efforts inte its Hantord diversification program. in 1064 Creneral Electric decided io withdraw trom Hanford and the AEC committed to use madtinie contractors io opersie the ate thereafer. , in the first major move of its Hantord diversification program, the ARCselected Battelle Memorial Institute of Columbus, (hie to take over operation ofthe Hanford Laboratories, which were now renamed the Paciiic horthwest Laboratory (FNL). At its inception PNIL hed a staff of about 1,800 and 2 budget of approxiunately 320 milkon. Under Battelle management the laboratory grew. In 1065 8 consisted ofa single gray barracks m downtown Richland. Wihin ten years, i included new buildings and euigment valued at $50 million. For example in 1947 PNT began operation of a 120 squere mile Arid Lands Ecology Reserve forthe AEC 1 established a Marine Research Laboratory on Washington's Obammic “Peninsula and « research center near the University of Weshington’s Seattle campus. It built a Richland Research Complex which inchuled a Research Onerations Building, a Physical Sciences Laboratory, a 300 seat auditorium, 2 Mathematus Building, an Engincerme Develooment Laboratory, and 4 Life Sciences Laborutory. In 1987 an observatery with the largest optical telescope in the Northwest was established near Richland. The AEC, meanwhile, had decided to build the Fast Flux Test Faciliry (PFTP) at Richland as part of its Hanford diversification efforts. The PPTF was an advanced muiclear reactor which would be used to test firels and materials which could be used in advanced muclear breeder reactors. PML was given the job of designing the FFTE and selecting engineering and construction firms to build if. Ad the same time PNL was diversifying its research programs. The lsborstory expanded its efforis into additional biomedical, nammclear energy, environmental, national security, and Iman affairs research, In 1969 PN waa chosen by the National Aeronautics and Space Asmmistration to analyze luner samples collected by the Apalia programand in 1072 PL received lunar samples from the Apollo 13 end 17 space miusions for research. In 197% the laboratory wona prestigious award for developing ¢ porqus substance that could develop a “Hving union” between bane and prosthetic devices by bone ingrowth. Aad By 1075 PNL's workforce totaled about 1142 and ite annual onerating budget waa a ltle over $25 million. By this time the ABC had been replaced bythe Enerey Research and Development Administration (ERDA) Within peo vears RIDA tad been replaced by the Department of Energy (DOE), PN became first an ERDA facility in [975 and then a DOE facility in 1277.
