CLARIFICATIONS OF ANPP-19099, OCTOBER 5, 1981 LETTER ITEMS

1. The results of studies called out in the "Corrective Action" columns of Attachment A HED 77 and 118 will be provided to the NRC 120 days prior to issuance of license.

2. Enclosed is a revised Attachment A clarifying HED's 4, 30 and 104.

3. Enclosed are revised sheets of Attachment B clarifying HED's 67 and 95.

4. Enclosed are revised sheets of Attachment C clarifying HED's 94, 98, 103 and 109.

5. Revised title on the first sheet of each attachment.

6. To further clarify HED 53, in our lighting survey of the real Unit 1 control room glare measurements will be retaken of the CRT screens to determine will be if any change to the "Corrective Action" is needed. This done 120 days prior to issuance of license.

7. Item 4a For HED's 1, 2, 3 and 32, we are currently investigating other fixes for detecting lamp failures. Lamp surveillance will be performed each shift.

8. Item 7 There will be appropriate relamping procedures.

9. Item 8 If the operator needs the discrete value for a parameter, other indicators on the panel will provide that value.

10. Item 10 Will review under Item 12.

ll. Item ll The addition of high speed printers review of system impact.
