Docket No. 50-333 Potential Pipe Support Design Non-Conformance 5
Reference:
NYPA letter, J.P. Bayne to D.
B.
- Vassallo, dated September 1, 1983 (JPN-83-79),
i concerning the same subject.
Dear Sir:
g As we informed you in the reference letter, the Authority h
retained United Engineers and Constructors (UE&C) as an independent third party to\\incestigate allegations regarding
=
pipe support deficiencies at FitzPa~trickh UE&C then met I
with the consultant who made the allegations to give him the opportunity to describe his concerns.
Based on the meeting, UE&C developed a review plan which included a representative sample of those pipe supports which were reanalyzed in 1979.
r b
The sample consisted of supports in critical, large diameter, high energy piping systems.
The evaluation being performed 7
by UE&C consists of a review of the Stone & Webster analytical
~
methodology, procedures and calculation packages.
In addition, UE&C performed field inspections of certain supports to verify
((
that the as-built and as-analyzed data agreed.
F-p UE&C has prepared a status report on their review efforts.
j A copy of this report is included with this letter.
Althotmh several items included as part of UE&C's review effort rera:
E to be closed out, the majority of the reviev's objectives
-p have been completed.
UE&C does not consider any of the open
~
items described in this report to be significant.

m As part of this third party review, UE&C made field inspections
[
to verify the Authority's line-walk (as-built) program.
In 3
the course of this field walk, certain discrepancies associated p
with several supports were identified. In most cases, these discrepancies involved the sizes of fillet welds.
Since i
these discrepancies are potentially significant, the Authority E
is taking immediate action to resolve them.
s
[
Upon receipt of the information regarding these discrepancies, the Authority initiated the following actions:
I 1.
Analysis by Stone & Webster of each support E
discrepancy to determine any safety significance.
=
2.
An inspection of each support identified.
?
3.
Review of existing in-service inspection files.
{
After this detailed evaluation is complete, we will assess the generic implications of any unresolved discrepancies.
5 The Authority will inform you of the results of our assessment as soon as it is completed.
At that time we will also L
address the potential for generic implications, and our i
plans and schedules for resolving the discrepancies, s
E The Authority will promptly inform you if there are any Z
significant changes in the findings.
If you have any ques-g tions, please contact Mr. J. A. Gray, Jr. of my staff.
