On January 10, 1980, the Philadelphia Electric Company (PECO) informed the NRC that the pneumatic supply for the Automatic Depressurization System (ADS) at Peach Bottom Units 2 and 3 might not be operable for all possible events. On January 11, 1980, IE Bulletin 80-01 was issued by the NRC to licensees of operating boiling water reactors (BWRs), because of concern about the possible safety-related deficiency reported by PECO. All BWRs were included in the issuance, including several which reported that they did not have pneumatically operated ADSs. The licensees were required to take six specific actions. On May 7, 1980, per TMI Action Plan Item II.K.3.28, NRC/NRR issued a letter to all operating BWR licensees requiring verification of qualification of ADS accumulators and changes to technical specifications. Early in 1983, 20 licensees of current BWRs were requested by NRC/NRR to supply additional information per Multi-Plant Action F-55. Evaluation of utility responses, NRC/IE inspection reports and NRC/NRR safety evaluation reports shows that the bulletin can be closed out per specific criteria for all of the 26 current BWR facilities to which it was issued. Documentation applying to related Item II.K.3.28 and Action F-55 is included in determination of bulletin closeout if necessary. TMI II.K.3.28 and Multi-Plant F-55 action items for nine facilities that have not been closed out by regional inspection are included for reference.
