DRAFT SAMA 8 Draft Response SAMA 8 The ER states that several cost-beneficial SAMAs exist that could be examined further. However, it is not clear which SAMAs will be further reviewed. Identify (list) which SAMAs Progress Energy plans to further evaluate, and describe the anticipated process for performing such an evaluation, e.g., the plant's action tracking system, or corrective action program.

Response

The ER identified seven cost-beneficial SAMAs as summarized below:

SAMA 1 - Portable generator of DC power SAMA 15 - Diverse EDG HVAC logic SAMA 17 - Alternate feeds to panels supplied only by DC bus 2A-1 SAMA 19 - Provide an alternate means of supplying the instrument air header SAMA 25 - Proceduralize battery charger high voltage shutdown circuit inhibit SAMA 29 - Portable EDG fuel oil transfer pump SAMA 36 - Use fire water as a back up for containment spray None of these SAMAs are age related.

All cost-beneficial SAMAs have been reviewed by the BSEP Plant Review Group (PRG). The PRG is responsible for oversight of plant projects. The PRG recognized that the high positive impact of implementing SAMA 1 could impact the cost-effectiveness of the remaining cost effective SAMAs. An evaluation was performed that found that, if SAMA 1 was implemented, SAMA 15, 25, and 29 would remain cost effective and SAMA 17, 19, and 36 would not. The reduction in averted cost-risk for these SAMAs indicated that the proposed changes impact some of the same sequences addressed by the installation of a portable DC generator. As certain failures are already reduced by SAMA 1, further reduction of those failures does not greatly impact the results.

Based on this evaluation, the PRG has directed that an assessment be performed to make recommendations for further evaluation of the cost-effective SAMAs. Completion of this evaluation is being tracked in the site's action tracking system.
