Origins The Price-Anderson Act is named for Representative
Charles Melvin Price (D-IL) and Senator
Clinton Presba Anderson (D-NM), both of whom eventually chaired Congress's Joint Committee on Atomic Energy. The Atomic Energy Act of 1946, which followed the development of nuclear technology during
World War II, had created a framework for operation of nuclear plants under government control. The intention of the government was to apply this technology to civilian industry, especially in using nuclear plants to generate electricity. In 1954, the
Atomic Energy Act Amendments Act removed the government monopoly on operating nuclear plants by creating a licensing system for private operators. The structure of the insurance industry as it existed until 1955 was incapable of providing the extent of coverage needed to adequately address the risks of nuclear power. The "amount of insurance required could not be underwritten at the time by any single or joint company effort". A power plant,
Shippingport, was eventually constructed, but electric utility executives expressed concerns about limited size of liability coverage offered by the insurance market ($60 million). A nuclear accident of privately held nuclear power appeared to be an impossible barrier since the possible magnitude of claims could bankrupt any electric utility held responsible. Nor could an insurance company offer insurance policies with limits beyond its own resources to pay. Because of these difficulties, it looked like it would be extremely unlikely that electric utilities would want to enter the nuclear power industry. The potential magnitude of worst-case accidents has been the subject of several major studies, such as
WASH-740,
WASH-1400,
CRAC-II, and
NUREG-1150. In November 2012, the
Nuclear Regulatory Commission (NRC) published
State-of-the-Art Reactor Consequence Analyses (SOARCA), which examines potential safety failures with probabilities of "occurring more than once in a million reactor years, or more than once in ten million reactor years for accidents that may bypass containment features". To address these issues, Congress introduced the Price-Anderson Act in 1957. The Act required companies to obtain the maximum possible insurance coverage against accidents, determined to be $60 million, and provided a further government commitment of $500 million to cover any claims in excess of the private insurance. Companies were relieved of any liability beyond the insured amount for any incident involving radiation or radioactive releases regardless of fault or cause. The act was intended to be temporary, and to expire in August 1967 as it was assumed that once the companies had demonstrated a record of safe operation, they would be able to obtain insurance in the private market. At the same time, Congress encouraged the insurance industry to develop a way that power plant operators could meet their financial protection responsibilities. The insurance industry responded by creating an insurance pool called American Nuclear Insurers (ANI), which today includes 60 U.S. property and casualty insurance companies who represent some of the largest insurance companies in the country.
Extensions By 1966, it had become apparent that the industry would still be unable to obtain adequate private insurance, so the act was extended until 1976. A provision was added to the Act which prevented companies from offering certain defenses to damages claims (particularly defenses which claimed that the accident had not been their fault). A minimum time limit was also introduced (which could be surpassed by state law), giving claimants three years after discovering harm in which to make a claim. The alterations were intended to make the process of obtaining funds from reactor companies easier, and to remove discrepancies in different states where different laws applied. The new provisions only applied to incidents where a significant escape of radioactive material was deemed to have occurred (an ENO, extraordinary nuclear occurrence). In 1975, the act was extended for 12 years, up until 1987. The total amount of insurance remained the same, but a provision was added requiring each of the 60 or so reactors then in existence to contribute between $2 million and $5 million in the event of an uninsured accident. The insurance ceiling for each individual company was increased to $140 million. These measures eliminated the contribution of the federal government to the insurance pool. However, an explicit commitment was made that in the event of a larger accident, Congress would take whatever actions were necessary to provide full and prompt claims to the public. This included the possibility of additional charges to reactor companies above and beyond the prescribed limits set forth in the Act. In 1988, the act was extended for 15 years up to August 2002. Individual insurance for each generator was increased to $200 million, and the total fund to $9.5 billion. For each reactor owned, the reactor company was liable to contribute up to $63 million towards compensation for any claim against any company, though this could only be recovered at a maximum rate of $10 million per year. Assessments were to be adjusted for inflation every 5 years. The same level of indemnity was provided for government DOE facilities, while small reactors (education and research oriented) were required to obtain $250,000 insurance and have a government-backed pool of $500 million in the event of accident. This extension provided that all cases resulting from a nuclear accident to be heard in a federal court, rather than local courts. In February 2002, the act was temporarily extended to December 2003. After some debate in 2003, the Act was extended to 2017. The individual insurance for each site was increased to $300 million while fund contributions per reactor were increased to $95.8 million. In 2005, it was extended again through 2025 via the
Energy Policy Act of 2005. In July 2024, the act was extended through 2045 as part of the
ADVANCE Act.
Usage Over the first 43 years of the Price-Anderson Act to 2000, the secondary insurance was not required. A total of $151 million was paid to cover claims (including legal expenses), all from primary insurance, including $71 million for
Three Mile Island. Additionally, the Department of Energy paid about $65 million to cover claims under liability for its own nuclear operations in the same period. == Constitutional challenge ==
