November 12, 1969 Li United States Atomic Energy Commission Division of Compliance Region I 970 Broad Street Newark, New Jersey 07102 Attention: Mr. Robert W. Kirkman, Director Gentlemen:

In response to your letter of October 22, 1969, to Mr. John E.

Logan, Vice-President, and attached Fom 592, please be advised that your letter has been given careful review with our operating personnel at our Oyster Creek Nuclear Station, and I would like to take this opportunity to answer your comments.

A Surveillance Program has been set up and is operational at Oyster Creek. Maintenance and miscellaneous problems associated with start-up have delayed some surveillance testing and the debugging of the entire Surveillance Program. A Surveillance Schedule Book has been generated, listing tests to be performed on a daily basis. The surveillance schedule cycles.every 84 days, which satisfies the once every three months criteria.

Feedback is being received from the personnel performing various tests with respect to time to complete the test, man hours required, and suggestions for a more efficient program. Also, since we have not con-sistently been in power operation, useful information and experience for an efficient Surveillance Program has not been fully developed as yet.

As with any new program, the initial phases are difficult and unknown problems have to be corrected. Such was the case at Oyster Creek in initiating and making operational a satisfactory Surveillance Program.

We have had an opportunity to observe our Surveillance Program in operation, and it is now sufficient to satisfy the Technical Specifications. Most of the problems have been alleviated and the program is progressing in a satisfactory manner.

.1 Mr. Robert W.~ Kirkman, Director November 12, 1969 i

f In response to the specific items listed in your letter of October 22, 1969, some deficiencies noted in the test and calibration frequencies were due to the above mentioned difficulties initially present' in our Surveillance Program. Tests had been performed in some cases, but the check-off sheets could not be located.

ITEMS A AND B I

On )hy ll, June 7, and August 2, 1969, the level trips on low L

level and low-low level were checked while lowering the level and assuring j

i that all five instruments were tracking although actual level measurements were not made in the vessel. Plant personnel erroneously felt that these tests were equivalent to instrument calibrations.

/i Iow-Low-Im Level Test On May 23 and June 7, 1969, the water level in the reactor was lowered to the top of the shroud for instrument work; and on both occasions

{

the low-low-low level instrument trips were observed to come in at the required point although no test sheet was ccanpleted. Again, personnel felt.

l that this was equivalent to a test but made out no data sheet.

I; ITEN C Frequency of "High radiation in reactor building - operating

[

floor" and "high radistion in reactor building - ventilation exhaust."

These tests or calibrations are now performed as required by Technical Specifications. Previously, the plant personnel erroneously used the manufacturer's curves as an indicator of calibration of radiation levels in the reactor building ventilation exhaust and operating floor.

(,

ITEM D Calibration delays to the monitor channels of the "high radiation on air ejector off-gas" were due to source handling problems which existed at the time. This calibration was performed on September.29, 1969 As for i

our failure to reset the monitor channels, it was felt that the method used for handling the source and holding it in the proper geometric position vould introduce a much greater error than actually existed in the instrument.

ITD4 D (con't)

A new method of supporting the source relative to the monitor is being pre-pared to accurately calibrate the instrument.

Very truly yours, A
