Attached for your review is Revision 13 of Byron Station's Inservice Testing (IST)

Program. The main purpose of this program revision is to incorporate the results of a combine Byron /Braidwood re-scoping effort, along with a few other minor changes. Reference 1, transmitted a Notice of Violation from the Nuclear l Regulatory Agency (NRC) concerning the " scope" of the IST Program. In reference 2 Commonwealth Edison Company (Comed) responded to that Notice of j Violation and committed to complete a scope review for pumps and valves by June '

30,1994, and to submit a revised program by September 14,1994.

Attachment A identifies all changes being made in Revision 13. Attachment B contains Revision 13 of Section 4 " Inservice Testing Program Plan for Valves,"

Section 4.4 " Notes," and Section 4.5 " Technical Approaches and Positions of Byron Station's Inservice Inspection Program."

Mr. Russell September 9,1994 l

Comed requests that the NRC review and approve relief requests VR-26, " Fire Protection Inside Containment Isolation Valves" and VR-27 " Charging and Volume Control Loop Fill Check Valves" on an expedited manner. Approval of these relief request is necessary, to avoid unnecessary testing of the valves every 3 m mths or during a cold shutdown condition. Testing of the Unit i valves will be conducted during the current refueling outage. Testing of the Unit 2 valves will be completed during the upcoming Unit 2 refueling outage, which is currently scheduled for February 1995.

Please address any questions you may have regarding this matter to Denise Saccomando at (708) 663-6484.

Sincerely, O/ s4 Denise M. Saccomando Nuclear Licensing Administrator l

B. Administrative /Tvnooranhical Errorse

1. 1/2 SIB 806: Removed "O" under " Stroke Direction" column. IST Program tested valve closed, but Rev. 11 contained Open stroke time test only. Byron conservatively just added the Closed direction in Rev 12 and investigated "O" direction. Scope Review j completion verified that the Open stroke time test is not i required. I
2. 1/2 SIB 926: Under " Test Mode" column, change "CS" to "RR" corresponding to the Full Stroke (Ct) Test (Approved VR-6 verifies this typo in the program) j
3. 1/2WM191: Under " Test Method" column, add "BT". This is the same test as the listed LT test. For completeness, however, the BT 4 test should be listed. l C. VR-12 Updates frevised relief cranted per GL 89-04. Position 6)-
1. 1/2CV8114: Added "VR-12" reference under " Relief Request" column due to the addition of of these valves to Relief Request VR-12 fo!!

the quick "open" stroke time of these valves.

2. 1/2CV8116
Added "VR-32" *eference under " Relief Request" column l due to the addition of these valves to to Relief Request VR-12 for the quick "open" stroke time of these valves.
3. 1/2PS9354B: Added "VR-12" reference under " Relief Request" column due to the addition of the 2PS9354B valve to Relief Request VR-12..

l

4. 1/2PS9357A: Added "VR-12" reference under " Relief Request" colamn due to the addition of the 1PS9357A valve to Relief Request VR-12. l
5. 1/2PS9357B: Added "VR-12" reference under " Relief Request" co?.umn due to the addition of the 1PS9357B valve to Relief Request VR-12.

Section 4.4 - Valve Notes / cold shutdown Justifications l A. scone Review Additions /Revisionst l

1 l 1. Added VC-1 Cold Shutdown Justification for the safety injection I

accumulator discharge motor operated valves (1/2 SIB 808A-D) for the closed direction.

. 2. Added VC-2 Cold Shutdown Justification for the RCP Seal Injection I

Inlet Motor Operated Valves (1/2 CV8355A-D) and Check Valves (1/2CV8368A-D).

3. Added VC-3 Cold Shutdown Justification for the Steam Generator blowdown AOV flow control / high energy line break (HELB) i Isolation valves (1SD054A, 1/2SD054B, ISD054C, 1/2SD054D, ISD054E, i 1/2SD054F, ISD054G, 1/2SD054H).
4. Added VC-4 Cold Shutdown Justification for the following letdown

! AOV isolation valves: 1/2CV459, 1/2 CV4 6 0, and 1/2CV8149A-C.

l B. Othert l l

1. Revised Note 30 to indicate that the backflow test for the AF014A- l H valves will be performed during Cold Shutdowns as recommended by region III Inspectors in addition to what is done shiftly during l' Operator Rounds. This will allow IST documentation every Cold Shutdown for this test. l l

Section 4.5 - valve Technical Annreaches and Positions l l

l A. scone Review Additions /Revisionse j

l

1. Revised VA-05 to incorporate the new CC manual valves added in this revision (1/2CC9458, 1/2CC9459A, 1/2CC9467A,7). VA-05 now justifies a U-2 Cold Shutdown frequency for all oi' the associated l

CC manual valves in the IST Program.

B. Administrative Revisionne l

l 1. Revised VA-02 to more clearly state Byron's position on fail safe testing. Words associated with MOV valves were removed from this j position.

Section 4.6 - Valve Relief Requests A. Scope Review Additions / Revisions:

1. New Relief Request VR-26 for the 1/2FP345 Fire Protection inside Isolation valves closure test. This valve is being added in this

! revision due to the scope review determination that they satisfy an IST function in the closed direction. This relief request is pending and Byron requests an expedited review and approval.

2. New Relief Request VR-27 for the 1/2CV8348 Charging and Volume Control Loop Fill Check Valves closure test. This valve is being added in this revision due to the scope review determination that they satisfy an IST function in the closed direction. This relief request is pending and Byron requests an expedited review and approval.
