GPUN Rceponse to SALP 89-99 )

on August 3, 1990, the NRC issued the Systematic Assessment of  ;

Licensee Performance (SALP) Report for Three Mile Island, Unit 1. 1 A meeti*g to discuss this report was held at the Three Mile Island l' Training Center on August 13, 1990. The attachment to this letter provides the GPUN written comments on the SALP Report.

We appreciate the opportunity to review the SALP Report with you and provide our comments. We continue to believe that this dialogue is the most meaningful portion of the SALP process.

GPUN is pleased that the NRC recognizes the high standards of performance of TMI-1 in the various SALP areas. We shall continue to l

[ direct our emphasis toward operating TMI in a safe and efficient l manner, and toward making further improvements.

GPUN also encourages the NRC to continue to conduct mid-SALP-cycle review meetings. We found this review to be a meaningful exchange of =

information and feedback.

Sincerely, ff P. R. Clark President and CEO PRC/DVM/spb 2116 cc T. Martin R. Mernan F,tYeung.. -

,, CPUN RESPONSE TO SALP REPORT 89-99 l i

The following comments are provided for purposes of clarification l "or accuracy -

Plant Operations _j The SALP Report' states that TMI will be the B& Woo pilot plant for l the installation of an advanced control system. The lead plant 1

)

has not yet been determined. At this time, TMI does not expect  ;

to be the lead plant but will be closely involved in the overall effort in this area.

Maintenance / Surveillance {;

Haintenance backlog goals have been established and the plant is-working to keep the backlog below these goals. Normally the L backlog has been within these limits but some exceptions have L occurred.

I t

During the maintenance team inspection and in the subsequent ,

inspection report there were several areas identified for TMI-1 improvement including six specific weaknesses. However, the SALP refers to143 specific areas of the maintenance program which were reviewed and 35 which were found to be well documented and  ;

functioning well. CPUN cannot specifically identify these 43 1 areas or the 8 areas where we may have been experiencing 7toblems. We are continuing to address the comments including ,

the specific weakneeses identified by the maintenance team i

inspection report. *

.In the surveillance discussion, the SALP Report indicates two violations were caused by inadequate procedures and lack of operator knowledge. In one case the violation resulted from lack -i of " technician" knowledge.

gmgIcenev Preparedtgag The SALP Report stated that GPUN was a day late in declaring an Unusual Event for the steam generator tube leak incident. In fact, CPUN did not declare an Unusual Event but did make an ENS notification. The notification was made in acc0rdance with 210CFR50.72 (b)(1)(1)(a) for a plant shutdown as required by the plant's Technical Specifications. In our notification we stated that had the leak rate been known to be greater than one gpm, an Unusual Event would have been declared in accordanet with the Emergency Plan.
