Dear Mr. Boyle:
@
J~
Subject:
P..:ific Gas and Electric Company, Diablo Canyon
h'
Units 1 and 2, Docket Nos. 50-275, 50-323
On August 3, 1977, we completed our investigation of the GA0 items of
g.%
concern identified during your audit of activities at the Diablo
cG.D
Canyon construction site and connunicated to us by telephone on
.<
$M
June 24, 1977 and your letter of July 22, 1977. The report detailing
QK
the NRC investigation findings, relating to rach item of concern, is
Qi?
attached for your information.
.
.-
In examining this report, you will note that some of the allegations made
'
by craftsmen were substantiated.
Ilowever, you will also note that most
,.
of these substantiated allegations simply addressed conditions which
hk
were being or had been addressed by the licensee or his contractors.
Therefore, they did not represent any failure to control quality.
s,
b
Our extensive investigation of those allegations resulted in only one
5A
finding of noncompliance. This finding resulted in the issuance of a
M
citation for failure to complete a weld inspection step during the
f3.) '
installation of pipe restraints. The welding on pipe hangers and restraints
g
(including inspection) has been a chronic problem at Diablo, as well as
b:.
other nuclear facilities. This arises because of the natural tendency to
7-Q
assign less experienced personnel to this type of work. At Diablo, a
p.
general program for upgrading hanger welding has been underway for the
past year.
