Dear Mr. DelGeorge:
-l
f
This refers to the inspection conducted by Mr. A. Dunlop of this office on
!
May 17-28, 1993. The inspection included a review of authorized activities
!
for your Braidwood Nuclear Power Station, Units 1 and 2. - At the conclusion of
the inspection, the findings were discussed with those members of-your staff.
identified in the enclosed report.

The areas examined during the inspection are identified in the report. These~
j
.
areas consisted primarily of a review of the Braidwood program for inservice
4
testing (IST) of pumps and . valves. Within these areas, the inspection
.
,
consisted of a selective examination of' procedures and representative records,
'
observations, and' interviews with personnel.
No violations of NRC requirements were identified during the course of this.
inspection.
'
l
One unresolved item is identified.in the report.
The item concerns stroke
l
timing power operated valves in one direction only when the valve has a safety '
{
function in both directions. This appears to be inconsistent with ASME
Section XI Code and NRC guidance issued with Generic Letter 89-04. .In
addition, we are concerned that neither your engineering personnel'nor your
quality verification process identified that a number'of. valves with safety
related functions had not been included in the IST program. You are requested
j
- to respond.to the unresolved item within 60 days of-your. receipt of.this
.
,
report.
Your response should include your evaluation of the issue and, if
1
.
applicable, your intended corrective action.
In accordance with 10 CFR 2.790 of.the Commission's regulations, a copy of:
this letter, the enclosure,'and your re'sponses to this letter will be placed.
in the NRC Public Document Room.
