VEGP-1 RR-9 Component or Relief Area Pressure-Retaining Bolting, greater than 2-inch diameter, in Class 1.
Reactor Pressure Vessel Studs ID Nos. Il201-V6-001-B1 through ll201-V6-001-B54 and spare studs 805-1 and BOS-2.
Reouirement from which Relief is Reouested item No. B6.30, Category B-G-1, ASME Code, requires surface and volumetric l examinations of Reactor Pressure Vessel studs when removed. Paragraph IWA 2232 (c) requires that the ultrasonic examination meet the requirements of Article 5,Section V.
Basis for Relief A more sensitive examination, wherein a shear-wave transducer is lowered into the heater hole in the center of the stud, has been developed. The calibration block contains 3 notches which were electrical discharge machined into the thread area with the following approximate dimensions:
Notch No. Lenoth Width Regth 1 0.942" 0.089" 0.060" 2 0.487" 0.089" 0.126" 3 0.387" 0.089" 0.148" This calibration technique will be used in lieu of the required bottom hole
- technique.
Alternate Examination The more sensitive shear-wave examination, as described above, will be used.
The Code required surface examination will be performed if the studs are removed.

Component or Relief Area l System hydrostatic test and VT-2 examination during system inservice test on i Class 3 vertical pit-type pumps. The following nuclear service cooling l water (NSCW) pumps and transfer pumps are affected by this relief request.
1-1202-P4-001 1-1202-P4-005 1-1202-P4-002 1-1202-P4-006 1-1202-P4-003 1-1202-P4-007 1-1202-P4-004 1-1202-P4-008 Reouirements From Which Relief is Reouested item number D1.10, Examination Category D-A, Table IWD-2500-1 of ASME Section XI requires a system hydrostatic test (IWD-5223) and a VT-2 examination during system inservice testing (IWD-5221) on Class 3 components.
Basis for Relief The NSCW pumps and transfer pumps are vertical pit-type pumps which take suction from the NSCW tower basins. Since these pumps are vertical pit-type pumps, there are no isolation valves on the suction side of the pumps to facilitate hydrostatic testing. Therefore, the performance of a hydrostatic test on the pumps and the piping to the first discharge shutoff valve is impractical. In addition, the performance of a VT-2 examination during system inservice testing is also impractical on the suction side portion of these pumps because they are submerged in the NSCW tower basins.
Alternate Examinations These pumps are periodically tested as required by Subsection IWP. These tests verify operability of these pumps and by doing so would detect significant leakages through the pressure retaining boundary. A VT-2 examination will be performed each inspection period during system inservice testing on portions of the pumps which are not submerged in the NSCW tower basin.

Component or Relief Area
! In addition to the relief requested from performing hydrostatic tests on the NSCW pumps and the piping to the first discharge isolation valve, it is 4
requested that the boundary be extended to the following:
discharge isolation valve 1-HV-11600 to discharge check valve 1-1202-U4-025, 1 discharge isolation valve 1-HV-11607 to discharge check valve 1-1202-U4-027, discharge isolation valve 1-HV-Il606 to discharge check valve 1-1202-U4-035, discharge isolation valve 1-HV-Il613 to discharge check valve 1-1202-04-037,
- discharge isolation valve 1-HV-Il605 to discharge check valve 1-1202-U4-031,
< discharge isolation valve 1-HV-11612 to discharge check valve 1-1202-U4-033, i
Train A to Train B intertie from manual isolation valve 1-1202-U4-492 to check valve 1-1202-U4-495, and
~
Train B to Train A intertie manual isolation valve 1-1202-U4-497 to check valve 1-1202-U4-493.
Reouirements From Which Relief is Reouested i
Same as original RR-49.
Basis for Relief l 1
4 Same as original RR-49 plus:
Performance of a hydrostatic test on the piping between the first discharge isolation valves downstream of the NSCW pumps and the downstream discharge check valves is impractical because no intermediate test connections are present to attach hydrostatic test equipment. To remove the check valve internals to facilitate hydrostatic testing is not prudent due to time constraints associated l with disassembling and reassembling the check valves and restoring the NSCW system to service.
l Similarly, portions of the "NSCW keep full system" are isolated from the
- remainder of applicable NSCW train by check valves with no intermediate test 1 connections. The "NSCW keep full system" is designed to maintain the idle train of NSCW pressurized and full of water by the use of an intertie from the operating train. To remove the check valve internals to facilitate hydrostatic l testing is not prudent due to time constraints associated with disassembling the check valves and restoring the NSCW system to service.
