(c): B. Rybak letter to H. R. Denton dated September 7, 1984.

Dear Mr. Denton:

By Reference (a), Commonwealth Edison submitted our Second Ten-Year Inservice Inspection and Testing (ISI and IST) Program.

~

Reference (c) submitted, based on questions raised by the Staff, additional information and two new relief requests (CR-ll and CR-12).

At that time Commonwealth Edison (CECO) committed to submitting an amended ISI/IST program after all questions concerning our program were resolved.

Enclosed.is six (6) copies of the amended ISI/IST program.

The' amended program not only reflects'the changes proposed in our

-September 1984 letter but also updates the valve list and deletes or modifies other relief requests. A summary of the changes are listed in the attachment to this letter.

The beginning of the second ten-year interval was February, 1983 for Unit ~1 and March 1983 for Unit'2. Reference.(b) granted relief. requests for the last 40 months of the first ten-year interval for the ISI portion of the program and suggests Commonwealth Edison follow the ISI; program proposed per Reference (a) as modified therein. No review of the IST' program was provided.

Therefore, given our . submittal of this amended ISI/IST program, CECO: requests interim approval of both the ISI/IST program l

.as submitted by.this letter. This interim approval should' allow use '

of the amended program until final approval is granted.

SUMMARY

OF CHANGES TO SECOND TEN-YEAR ISI/IST PROGRAM

1. Update snubber list to include new mechanical snubbers of class 1, 2, 3 and to delete hydraulic and non-class snubbers.

'2. Relief. request CSR-1 has been deleted. Snubbers must be tested.

3. ETO use the term class-code flagged piping and Instrument Diagrams instead of color-coded Piping and Instrument diagrams.

'(Pages~1-2, 5-1, 5-2)

4. Add the following valves to valve list:

, (a) _ Scram Discharge Volume (SDV) Valves (drains and vents) 1(2)-302-21A 1(2)-302-22A

.l(2)-302-218- 1(2)-302-228 1(2)-302-21C 1(2)-302-22C 1(2)-302-21D' 1(2)-302-22D (b) Pressure Suppression Valves (vacuum breakers)

-1(2)-220-105A 1(2)-220-1058

.l(2)-220-105C 1(2)-220-105D 1(2)-220-105E

5. Delete the'following valves. Not a pressure-containment isolation' valve:

1(2)FCV-2599-1A

'1(2)FCV-2599-1B

6. :0elete relief request No. VR-13. -Check _ Valves 1(2)-1402-12A, B;-

'byfpump test.

7. Delete' relief request'No. VR-12. .The'SDV drain andtvent valves twill be tested and timed at cold.-shutdowns. New' drain and vent valves were added to justification No. J-9.

18. Change relief valve testingJfrequency;to 6 months (Tech Spec requirement) on~ relief request.VR-1.

9. Revise relief request No. VR-14 to include vacuum breaker valves- 1(2)-220-105A to 1(2)-220-105E.

10. - Drop time criteria of 5 seconds for Diesel Generator Starting Air valve A0-1(2)(1/2)-4699-226 and write a relief request No.

VR-16 to explain that a successful Diesel Generator starting is a satisfactory test for the Diesel Generator Starting Air Valve.

11. Include relief request CR-ll to reflect the ultrasonic

' inspection problems of the N10 nozzle (SBLC) due to the geometry of that nozzle.

12. Add relief request CR-12 to delete the HPCI turbine hydrostatic test. . Fragile design of the labyrinth seals were not intended to retain waterfunder pressuit. Therefore, a hydrostatic test would. permanently damage the turine seals.
