Gentlemen:

A hII.DINIAELECTRICANDPOVERCOMPANY NORTH ANNA POWER STATION UNITS NO. 1 AND 2 PROPOSED TECHNICAL SPECIFICATION CHANGES Our letter of April 30, 1985 (Serial No. 290) requested amendments,in the form of changes to the Technical Specifications, for North Anna Units No.

I and 2.

The proposed changes involved updating the pressure-temperature limit curves to be applied during heatup and cooldown, in accordance with 10 CFR 50 Appendix G and H.

It was recently brought to our attention by Mr. Leon Engle of your staff that Attachment 3 to our letter, entitled

" Safety Evaluation",, contains several typographical errors which should be corrected.

The errors, which are contained in Table 2 of the attachment, do not affect the conclusions of the safety evaluation, or the proposed changes to the Technical Specifications. A corrected Table 2 is attached.

We apologize for any problems these errors may have caused you and your.

staff.
