Subject:
Request for Exigent Technical Speci-fication Change.
Dear Mr. Knighton:
References 1
and 2 requested changes to the PVNGS Units 1
and 2 Technical Speci-fication Tables 2.2-1 and 3.3-2.
One of the values for which a change was requested is called BAND, in the Technical Specifications, but the supporting analysis uses a term called STEP.
Please note that both of these terms may be used interchange-ably.
Attached to this letter is a table, comparing the values for the present set points and the new set points, which was requested by Mr. Licitra of your staff.
If you have any further questions, please contact Mr.
W. F. Quinn.
Very truly yours, JGH/RAB/rw Attachment J.
