Docket No. 50-29 I Yankee Atomic Electric Company ATTN: Mr. L..H. Heider Vice President of Operations 1671 Worcester Road Framingham, Massachusetts 01701 Gentlemen:

Subject: Systematic Assessment of Licensee Performance (SALP) Report No.

50-29/85-98 This refers to the SALP for the Yankee Nuclear Power Station, conducted by this office on December 4,1986 and discussed with you and your staff at a meeting on January 6, 1987. The list of meeting attendees is attached as Enclosure 1. The NRC Region I SALP Report is provided as Enclosure 2 and covers the period February 1, 1985 through October 6, 1986. Your response dated January 14, 1987, submitted l

pursuant to our letter of December 30, 1986, confirmed receipt of the SALP Report and did not request changes to the report content. These letters are provided as Enclosures 3 and 4.

Our overall assessment of' activities at your facility during the assessment period is that your performance reflected a commitment to quality operations, with a con-sistent and strong orientation towards nuclear safety. Because of your continuing record of superior performance, the Yankee Nuclear Power Station has been selected for reduced level of inspection effort by NRC Region I specialists.

No reply to this letter is required. We believe our meeting with you and the re-sulting interchange of information were beneficial and improved mutual understand-ing of your activities and our regulatory program.

Your cooperation is appreciated.

Sincerely,

. Original Signed By:

Thomas E. Murley Regional Administrator

Subject: Systematic Assessment of Licensee Performance (SALP) Report Number 50-29/85-98 On December 4,1986, the NRC Region I SALP Board reviewed and evaluated the per-formance of activities associated with the Yankee Nuclear Power Station. This assessment is documented in the enclosed SALP Board Report. A meeting has been scheduled for January 6, 1987 at 10:00 a.m. at the site to discuss this assessment.

That meeting is intended to provide a forum for candid discussions relating to the performance evaluation.

At the meeting, you should be prepared to discuss our assessment and your plans to ensure improved or continued emphasis upon those activities which would have a positive effect upon performance. Any comments you may have regarding our re-port rrsy be d'scussed. AdditienC ly, you may provide written comments within 30 days after the meeting.

Following our meeting and receipt of your response, the enclosed report, your written response (if deemed necessary), and a summary of our findings and p,lanned actions will be placed in the NRC Public Document Room. ~ ~ ~

Your cooperation is appreciated.

Sincerely,
