SUMMARY

OF MEETING TO DISCUSS IMPLEMENTATION OF DEGRADED VOLTAGE PROTECTION BACKFIT (TAC NOS. MD0022 AND MD0023)

On May 10, 2006, the Nuclear Regulatory Commission (NRC) staff met with I&M personnel to discuss its proposed implementation of the backfit of degraded voltage protection. The backfit was imposed by a letter, C. Haney (NRC) to M. K. Nazar (I&M) dated November 9, 2005. The licensee responded by a letter dated February 8, 2006. is the list of meeting participants and observers. Enclosure 2 is the licensee's handout, and is now available at NRC's Agencywide Documents Access and Management System (ADAMS), Accession No. ML061310037. Participants discussed the following items:

(1) The NRC staff was concerned about the two refueling cycles needed for each unit to complete the requirements of the backfit. The license was asked to manage its schedule such that the corrective actions are completed no later than 2008.

(2) The NRC staff expressed concern that the licensee's proposed interim compensatory measures did not include plant data to verify entry into degraded voltage conditions and recovery within acceptable time limits. The licensee agreed to look into the available computer data points for addressing this issue.

(3) The licensee was advised to expeditiously request approval of licensing basis changes via the amendment process should the licensee determine the need for such during its evaluation using provisions of 10 CFR 50.59.

Participants agreed to hold the next meeting as soon as the licensee had selected the option for the backfit.
