| |
| To correct the problem of plant procedures not being revised as required, a task force was established to review the incident and has made its recommendations to plant management.
| |
| Based on these racommendations, appropriate controls are being incorporated in a procedure upgrade to prevent future occurrences. The plant is currently undergoing a major rewriting of its administrative instructions for procedural revisions. This upgrade will include independent second party reviews, additional control not currently in use, and temporary revision controls. Due to the magnitude of the changes being implemented and the time required to train plant reviewers on these new requirements, it is not anticipated that the procedure will be approved and in use until July 31, 1983.
| |
| Until those controls are finalized, the General Manager has directed that the Plant Nuclear Safety Committee (PNSC) not approve temporary revisions requiring a permanent revision unless the permanent revision accompanies the temporary change.
| |
| If an exception is required, it will be tracked on management's daily Immediate Attention List, until completion, to assure it receives adequate attention.

| |
| BSEP Unit No. 2 Event Date: February 23, 1983 While performing the High Steam Line Radiation Channel Calibration and Functional Test, PT-01.1.12PC, it was determined that drawers A and D were out of calibration. The drawers were recalibrated and returned to service.
| |
| While researching several concerns expressed by tha Resident Inspector, it w s determined that the procedure used to perform weekly functional tests on the D instrument had not been revised as required on December 14, 1932, to reflect new calibration data derived from the December 14 calibration on the D drawer.
| |
| This failure to revise the functional test allowed operation of the D drawer from December 12, 1982, to February 23, 1983, without proper testing being performed. The sequence of events for this procedural error was as follows:
| |
| December 14, 1982: While performing the weekly functional test, it was determined that the D drawer needed to be recalibrated. A calibration was performed and new baseline data was established for the D drawer only.
| |
| December 16, 1982: The weekly functional test was performed on all drawers, with a temporary revision reflecting the new baseline data from the calibration on the D drawer.
| |
| Administrative controls were not adequate to assure that a permanent revision was made to the weekly functional test; therefore, subsequent tests reflected pre-December 14 baseline data.
| |
| December 23, 1982-February 16, 1983: Functional tests were performed on a weekly basis using pre-December 14 data.
| |
| A past review of these tests indicates that they were in specifications for the pre-December 14 baseline data, but exceeded the required baseline data on each performance.
| |
| February 23, 1983: The periodically required calibration was performed on all drawers and the A and D drawers were found out of calibration and were recalibrated. After this event, all required procedures were properly revised to reflect the new baseline data and have been satisfactorily performed since.
