WNP-2 PRESERVICE If1SPECTION PROGRAM MEETING TOPICS 1.
For some Class 1 and 2 welds, the WNP-2 preservice inspection plan utilizes Edi-tions and
- Addenda of the Code that are not approved by 10 CFR 50.55(a).
For those cases where examinations have not been performed in accordance with approved ASME Code Editions and Addenda, the application must provide a technical justifi-cation for the use of alternative examinations.
2.
WNP-2 states that remote mechanized ultrasonic examination calibration checks shall be perfonned at intervals not to exceed 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> instead of at intervals not to exceed 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> as required by Section XI, I-4230.
Confirm that calibra-tion over the intended 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> calibration interval maintains accuracy and sta-bility as required by I-4230.
3.
WNP-2 states that RHR pump welds are inaccessible.
Is this access limitation only for ultrasonic volumetric examination, or are other examination methods limited also?
4.
WNP-2 states that no ultrasonic examination on Class 2 piping welds (circumfer-ential and longitudinal) with piping walls h inch or less will be performed. This action is not provided for in the 10 CFR 50.55a approved ASME Code,Section XI, 1974 Edition, Summer 1975 Addenda.
The later 1977 Edition up to and including the Summer 1978 Addenda does allow exempting Class 2 piping with walls h inch or less; however, portions of approved editions or addenda may be used provided that all related requirements of the respective editions or addenda are met.
The pre-service and inservice inspection program plan should be modified wherever later 10 CFR 50.55a approved Code editions and addenda are involved to specifically identify the edition and addenda.
5.
WNP-2 states that no ultrasonic examinations will be perfonned on Class 1 piping welds less than 4-inch nominal pipe size.
10 CFR 50.55a has approved the use of the Section XI,1974 Edition up to and including the Summer 1975 Addenda, IWB-1220(b)(1) which states:
"Under the postulated conditions of loss of coolant from the component during normal reactor operation, the reactor can be shut down and cooled down in an orderly manner assuming makeup is pmvided by the reactor coolant makeup system only. However, in no instance may the size exemp-tion be more than 3 in. nominal pipe size."
(
. Additionally, normal makeup systems are those systems that have the capability to maintain reactor coolant inventory under the respective conditions of startup, hot standby, operation or cooldown, using onsite power.
The term onsite power is that power available to the nuclear plant from onsite without any power being supplied from an offsite power distribution system.
The following information concerning piping size exclusions should be provided:
(a) Confinn your calculations for liquid and gasecus fluid piping for which Paragraph IWB-1220(b)(1) exemption is invoked.
(b) List the systems and line sizes that were exempted from preservice exami-nation based on Paragraph IWB-1220(b)(1) of the 1974 Edition including Sunmer 1975 Addenda,Section XI based on nonnal makeup systems using only onsite power.
6.
The WNP-2 preservice inspection program plan does not discuss or define as inspec-table sys tems, the control rod drive cooling water lines common charging and dis-charging headers, and the control rod insert / withdrawal lines.
Identify the ASME
. Code. classification of each of these piping systems and discuss the technical basis for your preservice examination requirements.
j Those piping system lines that are exempted by IWB-1220(b) and which are parallel j
pathed into a common header that is larger in size than allowable by IWB-1220(b) should be identified and the coninon header lines shall be included in the PSI examination program.
7.
WNP-2 has included in the PSI Program, Table 5.2-12, Items B.4.1 and B.4.5, "Exami-nation Area" as follows:
" Safe end-to-piping welds, safe-ends in branch piping welds circumferen-tial and longitudinal welds to include base metal for a distance of is T or 1 inch, whichever is smaller."
l l
The 1974 Edition of Section XI including addenda through Sunmer 1975 cited as the Code being used by WNP-2 requires that base metal examination area include, at
^
least, one-wall thickness beyond the edge of weld.
Discuss the technical basis l
for your decision for selecting the examination area.
l
,.,. - g
( 8.
In Table 5.2-12, Item B-1.4, it is stated that primary nozzle-to-vessel welds and nozzle inner raduis components will be examined from the outside surface. Confi rm that existing procedures and equipment have been qualified on calibration mockups /
standards that enable fatigue cracks to be reliably detected, identified, and characteri zed.
9.
WNP-2 has invoked examination criteria sizing of 2 inches and smaller for category B-G-2 and larger than 2 inches for category B-G-1 as allowed by the 1978 Addenda to the 1977 Edition of the ASME Code,Section XI.
Confirm that all related exami-nation requirements of the 1978 Addenda to the 1977 Edition are being met.
10.
WNP-2 states in the PSI Program Plan sampling limitations as follows:
a.
For Item B6.4, Category B-K-1, " Integrally Welded Supports" and Item 86.5, Category B-K-2, " Support Components" of Table 5.2-12, only valves in Cate-gory B-M-1 will be examined.
It is not the intent of Category B-K-1 and Category B-K-2 to be limited to the sampling of Category B-M-1 of ASME Code,Section XI.
b.
For Item B5.4, Category B-K-1, " Integrally Welded Supports" and Item B5.5, Category B-K-2, " Support Components" of Table 5.2-12, only pumps in Category B-L-1 will be examined.
It is not the intent of Category B-K-1 and Category B-K-2 to be limited to the sampling of Category B-L-1 of ASME Code,Section XI.
c.
For Item B5.9, Category B-G-2, " Pressure Retaining Bolting 2 Inches and Smaller in Diameter" and Item B6.2, Category B-G-1, " Pressure Retaining Bolts and Studs Greater than 2 Inch Diameter" of Table 5.2-12 only pumps l
in Category B-L-1 and valves in Category B-M-1 will be examined.
It is not the intent of Category B-G-2 and Category B-G-1 to be limited to the sampling of Category B-L-1 and Category B-M-1 respectively of the ASME Code,Section XI.
Confirm that all required examinations of the above categories will be performed as part of the PSI Program.
