IE Bulletin Followup For the IE Bulletins listed below the inspector verified that the written response was within the time period stated in the bulletin, that the written response included the information required to be reported, that the written response included adequate corrective action commitments based on information presentation in the bulletin and the licensee's response, that licensee management forwarded copies of the written response to the appropriate onsite management representatives, that information discussed in the licensee's written response was accurate, and that corrective action taken by the licensee was as described in the written response.
IE Bulletin 80-14 Degradation of Scram Discharge Volumn capability.
IE Bulletin 80-17 (Including Supplements 1, 2, and 3, and Confirmatory Order) Failure of 76 of 185 Control Rods to fully insert during a Scram at a BWR.
The results of this inspection, in addition to a review of licensee
-
responses to IEB's 80-14, 80-17 and the supplements to 80-17 were used as a basis for completing the request for information to close out these bulletins and prepare requested input for the preparation of a Safety.
Evaluation Report (SER) for BWR's affected by IE Bulletin 80-17.
Within the scope of items-inspected, it appears that the licensee has satisfied the requirements of the referenced Bulletins. The detailed-results of the inspection, which will be used to prepare the aforemen-tioned SER, are documented in R.. F. Heishman's Memorandum of November 7, 1980 to E. L. Jordan, " Evaluation and Close Out of Responses to Bulletin 80-17, Failure of Control Rods to Insert During a Scram at a LBWR."
