Nuclear Waste Policy Act 1982

In 1998, U.S. Department of Energy (D.O.E.) by contract was tostart taking title to spent fuel

Operators pay 1/10 per kWh to cover cost of long term storage

solution

National Nuclear Waste Fund stands at $26B1

Pilgrim has paid over $150M into the fund

If D.O.E. fulfilled its obligation Pilgrim would not need dry storage
