Denton, Director Office of Nuclear Reactor Regulation U.S. Nuclear Regulatory Commission Washington, D. C. 20555

Dear Mr. Denton:

The purpose of this letter is to request an extension to October 31, 1980 for submitting the information requested by "Enclosure 2" of Hr. Eisenhut's letter dated October 30, 1979 concerning the Auxiliary Feedwater System Flow Design Basis. We have been working closely with Westinghouse to provide responses to the questions of Enclosure 2. However, the requested extension for submittal is necessary for us to complete our own in-house review'hich includes providing information that is not within Westinghouse's scope. We do not anticipate any further problems in meeting the revised submittal deadline of October 31, 1980.

Additionally, the attachment to this letter contains further informa-tion concerning the Condensate Storage Tank (CST) level indication system as discussed, over the telephone, with members of your staff on August 13 and 14, 1980. We believe, on the basis of the information provided in the Attachment, that we are in complete compliance with the requirements of Additional Short Term Recommendation 1 of Nr. Eisenhut's letter of October 30, 1979 and that this matter can be closed.

Very truly yours, P)e j 5

Additional Short Term Recommendation No. 1

~

On August 13, 1980 we were informed by the NRC staff that=they would not accept AEP's position, as stated in our letter of June 26, 1980 (AEP:NRC:0307C), that our present design meets the intent of the NRC position for redundant indication of Condensate Storage Tank (CST) water level. As such, we are leaving our present pneumatic system design as it is and we will installing be an additional indication channel to comply with the NRC position on redundant indication. Specifically, we are installing a control room, panel-mounted,'indicator through separat'e circuits and supplies from the existing level monitoring system. This new level 'ower monitoring channel will be electronic in nature (rather than pneumatic) and will consist of a transmitter device connected to the CST through its own piping (sensing line) with its output circuit connected to a 0-100/ level indicator in the control room. This new level indication channel plus our existing system fully complies with the NRC's position for redundant, indications and closes out additional short term Recommendation No. l. At the present time, we anticipate that this installation will be implemented by January 1, 1981.
