Licensee Action on Previous Ins ection Findin s
(Closed) Violation 50-410/84-08-01:
Failure to record and disposition minimum pipe wall thickness.
This item remained open (Inspection Report 50-410/85-16)
pending verification of the acceptability of weld No.
09-6-2-WCS-008-861-FW006.
The inspector reviewed documentation which confirmed that the weld was repai red and that the repai red area was sub-jected to ultrasonic thickness measurements.
The reviewed documentation

indicated that the thin wall was corrected and the weld was accepted by g.
C.
based on the results of the ultrasonic thickness measurements.
This item is considered closed.
(Open) Construction Deficiency 50-410/84-00-49:
Minimum pipe wall thick-ness violations.
This item involves numerous discrepancies regarding pipe wall thickness and is under investigation by the licensee.
The item will remain open pending completion of licensee actions and subsequent NRC review.

Preservice Ins ection PSI Pro ram The inspector reviewed the PSI Program Plan as prepared by the Stone and Webster Engineering Company, the licensee's agent.
The Program Plan is intended to meet the requirements of the 1980 Edition of ASME Section XI through Winter 1980 Addenda.
The Program Plan appeared to be in need of clarification in some areas, examples of which follow:
2.
ASME Class 1 piping welds falling under category B-J require volume-tric and/or surface examination per the Code.
The licensee's program includes visual examination requirements in addition to the code requirements of this category.
The licensee's representative stated that the visual examinations were included because they are required by code-required hydrostatic tests.
How-ever,,the inspector pointed out that these inspections are covered by code category B-P which defines the applicable requirements asso-ciated with system hydrostatic tests.
Per the Code, not all ASME Class 2 items are required to be included in the PSI program.
The various code categories define the number and type of items which must be included and the applicable exami-nation requirements.
The licensee's Program Plan lists all Class 2 items and does not specify which items are intended to be part of the program, and which are not in the program.
3.
The ASME Code lists items according to examination category beginning with category B-A for Class 1 and with category C-A for Class
items.
The licensee's.
plan was in alphabetical order by system, and did not follow the ASME Code format.
The required information was included but in a manner that is unnecessarily complex and confusing.
The concern with the plan is that it may become unmanageable and subject to error During the course of the inspection, and at the exit meeting the above concerns were discussed with the licensee.
At the exit meeting the inspector was informed that a program revision would be ready during the week of July 21, 1985, which would address concerns voiced by the inspector and by NRR.This revision will be subject to subse-quent NRC review to assure its suitability for implementation (410/85-23-01).
No violations were identified.
4.
Observations of PSI in Pro ress The inspector observed nondestructive examinations in progress to ascertain that procedural requirements were met and that applicable ASME Code licensee commitments, and regulatory requirements were met.
The following were included in the inspector's observations:
~
8 inch diameter weld ¹2-WCS-09-14-FW012;
~
8 inch diameter weld ¹2-WCS-09-14-SM031;
~
20 inch diameter weld ¹2-RHS-66-55-SM016.
The 8 inch diameter welds were ultrasonically examined in accordance with procedure number 80A7719 and the 20 inch diameter weld was examined using the liquid penetrant method in accordance with procedure number 80A7720.
An indication revealed by the liquid penetrant examination was recorded and documented as required by procedural requirements.
The examination personnel were found to be qualified to perform their assigned duties.
No violations were identified.
5.
Review of Nondestructive Examination Data The inspector reviewed data associated with the following welds:
Ultrasonic Examination
~
Weld 2-WCS-09-14-FW012
~
Weld 2-WCS-09-14-SW031
~
Weld 2-MSS-01-6-FW001 Li uid Penetrant Examination
~
Meld 2-RHS-66-65-SW016 The review was done to ascertain that findings were properly recorded and evaluated, and that ASME Code and regulatory requirements were me \\
Indications which were identified by the ultrasonic method were recorded, plotted and dispositioned based on the plotted location of the reflectors.
The liquid penetrant examination was done to satisfy ASME Section III and Section XI requirements.
A recorded indication was initially judged to exceed Section III acceptance standards on 2-RHS-66-65-SW016.
The Section XI examination was voided and will be redone subsequent to satisfying
,Section III requirements.
No violations were identified.
