the time. The restrictions of the act related to secrecy, the control of fissile materials, the ownership of patents and the operation of production facilities placed a number of legal roadblocks in the way of private nuclear power stations. This was at odds with the Eisenhower administration's Atoms for Peace program, and resulted in pressure on federal officials to develop a civilian nuclear power industry that could help justify the government's considerable expenditures on the nuclear weapons program. In 1953 the Atomic Energy Commission presented a set of draft amendments to the Joint Committee on Atomic Energy for consideration. After some debate, this resulted in the Atomic Energy Act of 1954. The Atomic Energy Act of 1954 proved insufficient in its objective of encouraging privately built and run nuclear reactors. A series of accidents with research reactors, including partial core meltdowns, made private companies cautious, and reluctant to become involved with nuclear energy without protection from liability. This led to the Price–Anderson Nuclear Industries Indemnity Act of 1957, which capped private liability for nuclear accidents, while providing for adequate compensations for accident victims. International relations Implementing the McMahon Act created a substantial rift between United States and Britain. The new control of "restricted data" prevented the United States' allies from receiving any information, despite the fact that the British and Canadian governments, before contributing technology and manpower to the Manhattan Project, had made agreements with the United States about the post-war sharing of nuclear technology. Those agreements had been formalized in the 1943 Quebec Agreement. In the case of the United Kingdom, these were developed further in the 1944 Hyde Park Agreement, which was signed by Winston Churchill and Franklin Roosevelt. The Hyde Park Agreement was lost in Roosevelt's papers after his death, and until the American copy of the document was found American officials were puzzled when the British mentioned it. The Quebec Agreement was an executive agreement that only applied to the Roosevelt administration, and the Senate had not seen the document. McMahon told Churchill in 1952 that "If we had seen this Agreement, there would have been no McMahon Act." The McMahon Act fueled resentment from British scientists and Churchill, and led to Britain developing its own nuclear weapons. Lewis Strauss, the Chairman of the Atomic Energy Commission, proposed in January 1958 that the President should be able to share nuclear information with allies that were making
