SALEM UNIT 2 -
lST INSPECTION INTERVAL FINAL RELIEF REQUEST -
- 1 COMPONENT DESCRIPTION:
Pressure vessels, components, and piping welds and integrally welded attachments subject to surface and/or volumetric examination.
ASME CODE CLASS:
ASME Section XI Class 1, 2 welds.
ASME EXAMINATION REQUIREMENTS:
In accordance with the examination requirements of Subsection IWB, Table IWB-2500 of examination categories: B-B, B-D, B-F, B-J and B-K-1 and Subsection IWB, Table IWC-2520 examination categories: C-A, c-c, C-E-1, C-F and C-G when an examination (surface or volumetric) is performed, essentially 100% of the weld length is required to be inspected.
BASIS FOR RELIEF:
The ASME Code requires surf ace and volumetric examination of various Class 1 vessel and piping welds as defined*in Paragraph IWB-2500 and various Class 2 vessel and piping welds as defined in Paragraph IWC-2500.
During the inservice examinations performed at SALEM NUCLEAR GENERATING STATION UNIT 2 it has been the position of PUBLIC SERVICE ELECTRIC AND GAS COMPANY that examinations which could not be performed completely, (i.e., performed from two (2) directions because of component configuration or restrictions from permanent structures) the examination would be performed to the greatest extent possible and whatever limitation that existed be documented.
It has also been PUBLIC SERVICE ELECTRIC AND GAS COMPANY'S position that when there was a "removable" structure, (i.e., hanger, support) these items were removed, when practical, providing greater access to the component being examined.
The basis for this position is as follows:
The Code of Federal Regulations, 10CFRSO, "Domestic Licensing of Production and Utilization Facilities" defines those requirements which must be adhered to by the utility in order to be issued and maintain an operating license.
This document states in Paragraph 55a(g) that inservice inspections shall meet the requirements of the ASME Boiler & Pressure Vessel Code.
Throughout 10CFRSO numerous references are made allowing performance of these inspections "to the extent practical".
Some of the specific paragraphs are:
Paragraph 50.55a(g)4 states that throughout the service life of a nuclear power facility components which are classified as ASME Code Class 1, 2 and 3 shall meet the requirements of Section XI of the ASME B&PV Code, "to the extent practical within the limitations of design, geometry and materials of construction of the components".
Paragraph 50.55a{2)i of this document states that inspection of systems and components is performed "to the maximum extent practical, in accordance with generally recognized codes and standards" i.e., ASME Boiler & Pressure Code.
Paragraph 50.55g(1) states that components (including supports) shall meet the requirements of (ASME Code) "to the extent practical".
The ASME Code itself provides allowance for "limited" examinations.
The 1986 Edition,Section V, Article 4, Paragraph T-441.3.2.4 states:
"Whenever feasible, the scanning of the examination volume shall be carried out from both sides of the weld on the same surface.
Where configuration of adjacent parts of the component are such that the scanning from both sides is not feasible, this fact shall be included in the report of the examination".
PUBLIC SERVICE ELECTRIC AND GAS COMPANY has utilized approved technical procedures written in accordance with the applicable Section/Paragraph of the ASME Code in regard to the area/volume to be examined and the specified requirements of the examination for the 1st inspection interval.
Recognizing that because of component design, construction, etc. there are cases when examinations can only be performed "to the greatest extent possible".
PUBLIC SERVICE ELECTRIC
& GAS has already submitted a list of those identified limitations after performing the preservice examination.
This relief request is submitted in addition to the original preservice examination list to identify limitations found while performing scheduled examinations for the 1st inspection interval.
ALTERNATIVE EXAMINATION:
Weld selection for this interval was made to minimize known limitations identified during preservice examination (PSI)
- For limitations found during the 1st inservice inspection interval, additional components were scheduled and examined, when possible, to meet the allocation table requirements of ASME Section XI 1974 Edition, Summer 75 Addenda.
Below is a listing by Category of all limitations found during the inspection interval and alternate exams performed, if any.
PSE&G requested and received approval for use of ASME Code Case N-460 in February, 1990 allowing a reduction of examination coverage not to exceed 10% of the required volume.
Utilizing that acceptance criteria, some of the exams listed below would no longer be considered limitations requiring relief requests.

Pressure Retaining Valves ASME CODE CLASS:
ASME Section XI, Class 1 Valves ASME EXAMINATION REQUIREMENTS:
Relief is being requested from the visual (VT) examination requirements of Table IWB-2500 Examination Category B-M-2 Item No.
B6.7.
BASIS FOR RELIEF:
The disassembly of functional valves during the first ten year inspection interval for the sole purpose of performing a visual examination of the internals would have increased the likelihood for component failure in the future and was contrary to good maintenance practices.
Considering the uncertainy of the benefit involved with this examination, it is difficult to justify the additional radiation exposure that would be incurred as a result of the disassembly,.
examination and reassembly these valves.
For example, estimates from radiation surveys performed on and around valve 2RH1 indicate that the total job dose that would be received in disassembling, examining and reassembling this valve be in excess of 4 man-rem.
Public Service Electric & Gas feels implementation of this examination is impractical for valves not scheduled for disassembly because of preventive or corrective maintenance.
In later editions of Section XI, this examination is only required to be performed on valves scheduled for disassembly for maintenance purposes.
ALTERNATIVE EXAMINATION:
Public Service Electric and Gas examined at least one valve in a valve group (valves of similar design and function) where at least one valve in the group was disassembled for maintenance purposes during the inspection interval.
If any valve examined was found to require corrective action, additional valves in that group would be disassembled and inspected as required by Section XI.
Utilizing the above guidelines, the following valves listed by group were never disassembled during the first inspection interval and therefore, the internals were not visually examined.
A similar relief request has been submitted for the second ten year interval per later editions of the Code

Relief is being requested from the ultrasonic (UT) examination requirements of Table IWB-2500 Examination Categories B-A, B-B and B-D, Item No. 's Bl.1, Bl.2 and Bl.4, respectively.
BASIS FOR RELIEF:
Due to the geometry of the reactor vessel and the proximity of some of the vessel penetrations, code required coverage of all the applicable welds cannot be obtained utilizing automated UT equipment.
ALTERNATIVE EXAMINATION:
Ultrasonic examinations were performed on as much of the weld geometry that could be examined.
For vessel welds in the beltline region (Categ. B-A), Public Service Electric & Gas attempted to perform a 100% examination of all the required vessel welds which exceeds the Code requirement to examine 10% of all circumferential welds and 5% of all longitudinal welds.
Attached is a listing of those welds where the Code required volume could not be examined due to geometry and interferences.

BASIS FOR RELIEF:
Some of the supports scheduled for examination during the inspection interval could not be examined due to their accessibility.
These supports cannot be examined because they are either encased within concrete or encapsulated by guardpipe.
In our submittal for Salem Unit 2, 2nd Ten Year Inspection Interval, Public Service Electric & Gas has requested the use of ASME Code Case N-491 which exempts these types of components from examination.
ALTERNATIVE EXAMINATION:
There are no alternative examinations proposed for these examinations at this time.
Below is a listing of those component supports which could not be examined during the 1st inspection interval.
