Years back, during the congressional hearings over the FPO (full power operation) permit for the Seabrook power plant on the east coast, I found out about a MOA (Memorandum of Agreement) between the US NRC (Nuclear Regulatory Commission) and INPO (Institute of Nuclear Power Operations), which is a private corporation that can be
hired by nuclear power operators for tasks such as investigating nuclear power plant safety deficiencies.
But the effect of it was to cause
nuclear power operators, upon notification
by the NRC of some intended safety evaluation per their responsibilities, to immediately
hire INPO, instead, to perform exactly the same required safety deficiency investigations that the NRC was expected to perform.
