Im)racticalitv/Burden caused bv Code Compliance Paragraph A: (The pipe to pipe cap material is stainless steel. The diameter of this weld is 2.00 inches with a wall thickness of.344 inches.
During the ultrasonic examination of this weld, 100% coverage of the required examination volume could not be obtained. Coverage was limited because of the proximity of an I-beam near the weld. The amount of coverage reported represents the aggregate coverage from all scans performed on the weld and base material. The required volume was scanned using 45-degree, 60-degree, and 70-degree shear waves. The 45-degree beam had an aggregate coverage of 88%
of the volume in two circumferential directions. The 60-degree beam had an axial coverage in two directions, 81.3% on the pipe side of the weld and 90.7% on the pipe cap side of the weld.
The 70-degree shear wave covered 100% of the inside surface from one axial direction from the pipe cap side of the weld but was not included in the percentage of coverage calculation because of the requirements in IOCFR50.55a(b)(2)(xv)(A)(2). In order to achieve more coverage, the I-beam would have to be redesigned to allow scanning from both sides of the weld, which i, impractical. There were no recordable indications found during the inspection of this weld.
Paragraph B: (The pipe to elbow material is stainless steel. The diameter of this weld is 3.000 inches with a wall thickness of.438 inches.)
During the ultrasonic examination of this weld, 100% coverage of the required examination volume could not be obtained. Coverage was limited because an area 3" long on the elbow intrados limited the scan surface in the throat area, which prevented scanning from four directions. The amount of coverage reported represents the aggregate coverage from all scans performed on the weld and base material. The required volume was scanned using 45-degree, 60-degree, and 70-degree shear waves. The 45-degree beam covered 100% of the volume in two circumferential directions. The 60-degree beam had an axial coverage in two directions, 72.7%
on the elbow side of the weld and 86.4% on the pipe side of the weld. The 70-degree shear wave covered 33.3% of the volume from one axial direction from the pipe side of the weld but was not included in the percent of coverage calculation because of the requirements in 10CFR5O.55a(b)(2)(xv)(A)(2). In order to achieve more coverage, the weld would have to be redesigned to allow scanning from both sides of the weld, which is impractical. There were no recordable indications found during the inspection of this weld.
Paragraph C: (The Tee to reducer material is stainless steel. The diameter of this weld is 3.000 inches with a wall thickness of.438 inches.)
Request Relief 05-MIN-002 Page 3 of 5 During the ultrasonic examination of this weld, 100% coverage of the required examination volume could not be obtained. Coverage was limited to the examination volume because of an area 3" long on the tee side of the weld due to the tee configuration, this prevented scanning from four directions. The amount of coverage reported represents the aggregate coverage from all scans performed on the weld and base material. The required volume was scanned using 45-degree, 60-degree, and 70-degree shear waves. The 45-degree beam covered 100% of the volume in two circumferential directions. The 60-degree beam had an axial coverage in two directions, 72.7% on the tee side of the weld and 86.4% on the reducer side of the weld. The 70-degree shear wave covered 33.3% of the volume from one axial direction from the reducer side of the weld but was not included in the percent of coverage calculation because of the requirements in IOCFR50.55a(b)(2)(xv)(A)(2). In order to achieve more coverage, the weld would have to be redesigned to allow scanning from both sides of the weld, which is impractical.
There were no recordable indications found during the inspection of this weld.
VI.
Proposed Alternate Examinations or TestingZ Paragraph G:
None. The scheduled 10-year code examination was performed on the referenced area/welds and it resulted in the noted limited coverage of the required ultrasonic volume. No additional examinations are planned for the area/weld during the current inspection interval.
VII.
Implementation Schedule and Duration Paragraph H:
None. The scheduled 10-year code examination was performed on the referenced area/welds and it resulted in the noted limited coverage of the required ultrasonic volume. No additional examinations are planned for the area/weld during the current inspection interval.
VIII.
Justification for Granting Relief Paragraph D: Ultrasonic examination of the weld for item RO1.011 was conducted using personnel, qualified in accordance with ASME Section XI, Appendix VIII, Supplements 2 and 3.
The examination was performed in accordance with the requirements of ASME Section VIII, Supplement 2. The 2" pipe to pipe cap weld is located on the 2B Cold Leg inside containment; this is part of the NC (Reactor Coolant System) boundary. This weld would normally see NC pressure leakage and would be noted per monitoring listed later in this paragraph. This weld is not exposed to significant neutron fluence and is not prone to negative material property changes (i.e., embrittlement) associated with neutron bombardment. If a leak were to occur at the weld in question, there are methods by which the leak could be identified for prompt Engineering evaluation. The plant is designed to detect the following:
Request Relief 05-MN-OD2 Page 4 of 5 a)
Increased containment humidity. This parameter is indicated in the control room and is monitored periodically by Operations and also monitored by the Containment Ventilation System Engineer. Ventilation Unit Condensate Drain Tank (VUCDT) level, and lower containment humidity are all recorded in Autolog at the start of each shift.
b)
Increased temperatures in lower containment, Steam Generator compartment, Pressurizer compartment, or incore sump room. These temperatures are monitored continuously by the OAC alarm, and are periodically monitored by the System Engineer. The OAC alarm is set for immediate Operations notification when an alarm set point is exceeded.
c)
Increased input into the VUCDT level. This parameter is monitored continuously by Operations via an OAC alarm and also periodically by the Liquid Radwaste System Engineer and Reactor Coolant System Engineer. The OAC alarm is set for immediate Operations notification when an alarm set point is exceeded.
d)
Increase in unidentified reactor coolant leakage. This parameter would be exhibited during performance of reactor coolant leakage calculation, which is required by Technical Specifications to be performed every 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. The unidentified leakage limit in Technical Specification 3.4.13.1 is 1 gpm.
e)
Increased Containment Floor and Equipment Sump levels. These levels are closely monitored by the Liquid Waste Recycle and Reactor Coolant System Engineer and alarmed for immediate Operations notification.
f)
Change in the Volume Control Tank (VCT) level rate (a more negative rate is set to alarm to Operations at -1.0 gpm). This is closely monitored by the Chemical and Volume Control System Engineer.
Note: Although diverse means are available to identify a leak in containment, containment entry would be required to identify the exact source of the leakage.
]n addition, a Mode 3 containment walkdown is performed each refueling outage at shutdown and startup to identify any leaks.
No additional NDE ultrasonic examinations were performed on welds 2.00",.344 wall thickness in this outage.
Paragraph E: Ultrasonic examination of the weld for item R01.01 1 was conducted using personnel, qualified in accordance with ASME Section XI, Appendix VIII, Supplements 2 and 3.
The examination was performed in accordance with the requirements of ASME Section VIII, Supplement 2. These welds are located on the outlet side of the IA Seal Water Injection Filter Outlet Isolation Valve (INV-494) and they are not exposed to significant neutron fluence and are not prone to negative material property changes (i.e. embrittlement) associated with neutron bombardment. The plant is designed to detect the following:
a)
Abnormal Volume Control Tank (VCT) level trends and/or unexpected auto make-ups.
b)
Increase in unidentified reactor coolant leakage. This parameter would be exhibited during performance of the reactor coolant leakage calculation, which is required by
Request Relief 05-MIN-032 Page 5 of 5 Technical Specifications to be performed every 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. The unidentified leakage specification in Technical Specifications 3.4.13.1 is I gpm.
c)
Increase in ND/NS Sump inputs. This parameter is monitored periodically by the Liquid Radwaste System Engineer.
d)
These welds are exposed to charging pump discharge pressure during outage testing PT/2/A/4209/012A, B and leakage would be noted during the startup containment walk down.
Three additional ultrasonic examinations were performed on 3.00",.438 wall thickness pipe welds in the NI System. The results from these examinations were acceptable with 100%
coverage.
Other Information Jim McArdle (Principal UT NDE Level III Examiner) provided Sections III., IV. V. and part of Section VIII.
Robert Kirk Jr. (MNS Systems Engineer) provided part of Section VIII.
Gary Underwood (Sponsor) compiled the remaining sections of this relief request.
