How Did The 1960s-era Debates Over The Merits Of Liquid Metal Fast Breeder Reactors Versus Gas-cooled Reactors In The United States Influence The Development Of The Country's Civilian Nuclear Power Program, Particularly In Terms Of The Role Of The Atomic Energy Commission And The Electric Power Research Institute In Shaping Reactor Design And Policy?

The debates between liquid metal fast breeder reactors (LMFBRs) and gas-cooled reactors in the 1960s significantly influenced the U.S. civilian nuclear power program, shaping both policy and reactor design. Here's a structured overview of the key points:

  1. Atomic Energy Commission (AEC) Role:

    • The AEC was a central player in promoting nuclear energy and initially championed LMFBRs due to their potential to breed fuel, enhancing efficiency and sustainability.
    • Despite the theoretical advantages, LMFBRs faced challenges such as complexity and safety concerns, which may have affected their adoption.

  2. Shift in the 1970s:

    • The AEC was restructured into the Nuclear Regulatory Commission (NRC) and the Department of Energy (DOE), leading to a policy shift towards commercial viability and safety.
    • The focus moved to light water reactors (LWRs), which were proven and more reliable, despite LMFBRs being initially seen as the future.

  3. Electric Power Research Institute (EPRI) Influence:

    • Formed in the early 1970s by electric utilities, EPRI focused on research and development to improve reactor safety and efficiency.
    • EPRI's efforts supported the adoption of LWRs, which became the industry standard due to their commercial success and EPRI's backing.

  4. Policy and Design Impact:

    • The debates and subsequent policy shifts led to the U.S. prioritizing LWRs over more experimental breeder reactors.
    • EPRI played a crucial role in ensuring LWRs were safe and efficient, solidifying their place in the U.S. nuclear program.

In summary, the AEC's initial support for LMFBRs gave way to a focus on LWRs due to practical considerations, with EPRI instrumental in their widespread adoption through research and development efforts. This transition shaped the U.S. nuclear power landscape, emphasizing commercial viability and safety.
