Plant Operations a.
Shift Log and Operating Records The inspector reviewed the following logs and records: Shift Supervisor's Log, April 1 - June 30, 1979 -, Control Room Operator's Log, April 1 - June 30, 1979 Auxiliary Building Log, April 1 - June 30, 1979 Jumper Log, April 1 - June 30, 1979 Night Order Book, April 1 - June 30, 1979 Surveillance Log, April 1 - June 30, 1979 The logs and records were reviewed to verify conformance to plant procedures, Technical Specification reporting requirements and Limiting Conditions for Operations (LCO).
The inspector noted that some of the signatures, QA stamps or initials were missing from a few procedures and logs. Further inquiry verified that the steps in the procedures and reviews of logs had, in fact, been completed. The inspector discussed this with the licensee.
The inspector was unable to determine whether this was an isolated case or the beginning of a trend. The licensee agreed to review the matter and to take the necessary steps to prevent the matter from becoming a serious problem. This item will remain unresolved pending the results of the review by the licensen (79-09-2a).
