Washington, DC 20555 Dear Mr Stello D
f 4 MONTICELLO NUCLEAR GENERATING PIANT Docket No. 50-263 License No. DPR-22 Revisions to Report of Conformance to 10CFR50, Appendix J, and License Amendment Request dated January 30, 1976 ke f:
(a) Letter from L 0 Mayer to K R Coller, USNR, da ted September 19, 1975 (b) Monticello License Amendment Request dated January 30, 1976 Reference (a) was our initial report of areas of nonconformance with 10CFR50, Appendix J, testing requirements at the Monticello Nuclear Generating Planc.
Reference (b) was a License Amendment Request revising the Monticello Technical Specification. ;o conform to Appendix J.
Evaluation of our ability to conduct testing in accordance with the Regulation has been continuing following submittal of these documents. As a result, a number of changes have been identified which should be made to them.
These changes are required for one or more of the following reasons:
a.
To correct an error in the initial document b.
To remove inconsistencies between the initial document and planned submittals of requests for exemptions from the requirements of Appendix J and planned modifications to permit testing in accordance with Appendix J To inc1nde the recently installed Nitrogen Recirculation System c.
Attached are 40 copies of a revision to Reference (a) and 40 copies of a revision to Reference (b). None of these changes affect the intent or the substanco of the original submittals.
Yours very truly, l
L 0 Mayer, PE l

j May 4, 1976 Revision to letter dated September 19, 1975 in.e. Mr L 0 Mayer, NSP to Mr K R Coller, UsiRC. "Monticello Compliance with the Requirements of 10CFR50 Appendix J" Replace Table 2 of the September 19, 1975 letter with the attached revised Table 2.
Changes in the original table arc indicated with lines in the margin.
- 1he following additional containment penetrations, which have been construed to require testing in accordance with Appendix J, are not testable.
Refer to Table 2.
Description Type Teg Reason Not Testable X-20 Demin Water Supply C
No test connection X-21 Service Air Supp1; C
No test connection X-29E Drywell Pressure B
No provision for testing 6
Sensing Lines X-29F X-32C Drywell Flood Level B

No provision for testing thru X-206D X-209A Torus Instrumentation B
No provision for testing thru X-209D X-229B Instrument Air to Torus C
No test connection
2 It has also been determined that there are several cases where primary containment isolation valves are leakage tested with the inboard valve pressurized in a direction Opposite to the direction of pressurization following an accident.
Test connections at Monticello have generally been provided in the connecting volume between the inboard and outboard isolation valves. The coanecting volume is pressurized and the pressure decay rate is measured.
In some cases there is no other provision for testing the inboard isolation valve.
The following penetrations can only be tested with at least one valve subjected to pressure in the opposite direction (refer to Table 2):
Type Valve X-18 Floor Sump Globe X-19 Equip Sump Globe X-25 Drywell Vent Butterfly X-26 Drywell Vent Butterfly X-27D 02 Analyzer Globe X-27E O Analyzer Globe X-27F 0 Analyzer Globe X-39A Drywell Spray B Gate - Wedge Type X-39D Drywell Spray A Gate - Wedge Type X-41 Coolant Sample Globe X-48 N2 Pumpback Globe X-205 Torus Vent Butterfly X-214 02 Analyzer Globe X-220 02 Analyzer Globe Except in the case of penetrationc X-39A and X-39B, testing of these valves in the reverse direction is permissible under the provisions of Section XI, Subsection IWV, of the ASME Code.

Table 2 tbnticello Cbatainment Penetrations Page 1,,,3 of 8 Explanation of Notes:
1.
Durirv:; refueling outages, when the vessel head is removed, MSIV's are tested by pressurization between valves. Since test pressure tends to uncent the inboard valve, a lover test presture than Pa is specified.
l 2.
Isolation is accomplished using manual valves in the containment supply line.
These valves are opened only when containment integrity is not required. The valves are closed in acconlance with valve lineup checklists which am completed prior to plant heatup.
i 3
One-inch instrumentation lines equipped with excess flow check valves. Subject to leakage testing in acconiance with Technical Specification L.7.D.l.b.
Icakage can occur only throu6h rupture of the line or its associated instrument outside of contniranent.
L 4
TIP probes are withdrawn on a containment isolathu signal and the line is isolated by autocatic closure of a ball valve. A shear valve can be manually netuated fmm the Control Room in the event a probe fails to retract. A solenoid valve in the purge supply line automatically closes on a containment isolation signal.
5 Containment isolation of the CRD hydraulic control lines is accomplished with a ball check valve internal to each drive mechanism and the nomally closed hydraulic system control valve.
6.
The dryvell air lock is constructed with both doors opening inward so that containment pressure. will tend to seat the door seals. During overall air lock pressure tests, a support r. :mber is installed on the inner door to prevent the door from being forced open.
7.
These are internal penetrations between sections of the containment structura.
8.

Leakage can occur only through rupture of 9
This penetration terminates at the bottom of the suppression pool.
