w o ATTACHMENT RESPONSE TO NOTICE OF DEVIATION 50-458/8624-01 REFERENCE Notice of Deviation - J. E. Gagliardo letter to W. J. Cahill, Jr.

dated October 23, 1986.

FAILURE TO VERIFY AND VALIDATE CERTAIN ABNORMAL OPERATING PROCEDURES REASON FOR THE DEVIATION During the initial Emergency Operating Procedure (EOP) verification and validation (V&V) phase, it was determined that some EOP steps were event oriented. To provide cohesive guidance to the operator and utilize good human engineering principles, event oriented EOPs were combined into existing plant Abnormal Operating Procedures (AOPs). In this process, documentation of the V&V of the new AOPs is not available. It is believed to have been an isolated oversight of OSP-0008, " Verification and Validation of Emergency Operating Procedures".

CORRECTIVE STEPS WHICH HAVE BEEN TAKEN AND THE RESULTS ACHIEVED AOP-0020, " Alternate Shutdown Cooling", AOP-0021, " Anticipated Transient Without Scram", and AOP-0022, " Radioactive Release Control",

are undergoing a rewrite in accordance with OSP-0009, " Authors Guide / Control and Use of Emergency Operating Procedures", to be incorporated as EOPs. Prior to approval and implementation they will receive a documented V&V in accordance with OSP-u008.

CORRECTIVE STEPS WHICH WILL BE TAKEN TO AVOID FURTHER DEVIATIONS A review was performed to ensure no other procedures exist outside the EOP's requiring V&V. Based on this review it is believed that this was an isolated event requiring no further corrective actions.

Procedures (OSP-0008, OSP-0009) are in place to require revisions to

  • he EOPs to be done in accordance with the procedure generation package (PGP).

DATE WHEN FULL COMPLIANCE WILL BE ACHIEVED V&V will be conducted on procedure revisions by January 30, 1987.

Further revisions necessitated from the V&V process will be incorporated, reviewed and approved by February 15, 1987. Shift crew training on the subject revisions will be provided prior to implementation.
