New London, CT 06320

Dear Mr. Beachy:

During our meeting on April 6,1998, we discussed the indicators that an electric utility could used to track its plant performance and benchmark against the industry average. For your information, I have enclosed examples of industry average Performance Indicators generated by NRC's Office for Analysis and Evaluation of Operational Data (AEOD) and the Performance Indicators generated by the World Association of Nuclear Operators (WANO). We also discussed that some plants that have the best safety records also operated economically. 1 want to provide you with two examples from NUREG/CR-6577, 'U.S. Nuclear Power Plant Operating Cost and Experience Summaries" that have relatively low operating costs and high cumulative capacity factors, namely, Monticello and North Anna Unit 2 (annual unit production i

cost around $80 million and capacity factors at 76% and 78%, respectively). These two nuclear stations not only operated economically but also have excellent iafety records as reflected in their recent Systematic Assessment of Licensee Performance (SALP) reports.

Again, I appreciate the opportunity to meet with you and I hope you find the above information helpful.

Sincerely,

,}
