2. Plant Tour - Units 1 & 2
.
The inspector observed work activities in progress, completed work and the plant status in several areas of the plant during general inspection of the plant. The inspector examined work for any obvious defects or noncompliance with regulatory requirements or license conditions.
Particular note was taken of presence of quality control, evidence such as inspection records, material identification, housekeeping and equipment preservation.
The inspector interviewed, when appropriate, craft personnel, craft supervision and QC personnel in the work areas.
During this tour, the inspector noted several drawings being used by the pipefitters and the
,
electricians. The drawings and their revisions or changes were then compared with the Bechtel Drawing Document Register to verify that the drawings were current. The following drawings were verified to be current:

3. ' Safety Related Piping and Pipe Supports'- Work' Activities ~(Unit 1)
The following work activities were observed to verify compliance with Regulatory commitments, codes and standard requirements:
a.
Piping erection activities in wetwell of primary containment i
Observed crafts performing an " informational" liquid
--
penetrant (LP) examination of weld joint HBB-ll7-3/13-1.
(Note:
LP is not required, only radiography. The crafts
who are not qualified in accordance with ASME code
'
requirements are examining the weld end preps on their i
own volition, prior to welding.)
Inspected completed weld HBB-109-2-FW1 and n'oted grinding
--
.
'
was done on inner diameter adjacent to root weld. The
inspector questioned if wall thickness was measured between l
the 5 and 8 o' clock location to determine that minimum wall tl11ckness l
was not exceeded. The cognizant QC' engineer stated:
'
it was measured and found to be acceptable. The inspector reviewed the final radiographs for this weld.
No items of noncompliance were identified.
b..
Piping activities in pipe tunnel
Observed repair of pipe hanger HBC-183-H2/2 in accordance
--
with inprocess rework notice #W404.
Observed installation of pipe hanger HBC-84-H16. During this
--
inspection the inspector noticed that adjacent to the hanger on the pipe surface what appeared to be a lamination. This was pointed out to the cognizant.QC engineer. An inprocess rework notice.#P1282) was issued to have this area ground,
'
penetrant examined and checked for wall thickness.
This work was accomplished and the area in question was found to be acceptable.
.
No items of noncompliance wtre identified.

c.
Piping activities in reactor building Observed the welding of branch connection (saddle)
--
i GBB-118-1/15-FW11 to ARHR pipe spool.
Inspected completed hanger HBC-143-H9 to verify compliance
--
with the drawing and design specification P-317. This par-ticular hanger had two 5/8" thick washer plates welded to

hanger support plate (required by design specification when alignment problems are encountered) under the bolts.
The inspector also reviewed the quality control inspection record (QCIRMll-HBC-143-2-5-1) to verify that longer bolts were used to obtain the minimum engagement.
No items of noncompliance were identified.
d.
Welding of instrumentation containment penetrations Inspected welding of stainless piping to flued head for
--
penetrations identified as X-63, X33A.
Inspected fit-up of flued head instrument penetration
--
identified as X-318. The flued head was tack welded in place.
Verified that a heatsink was provided adjacent to weld
--
joints so that the flow limiting valves shown on drawing 8031-M-231-1-10 do not exceed maximum temperature of 5860F during welding.
No items of noncompliance were identified.

4.
Electrical Support Bracket Welding (Unit l)
The inspector inspected the welding being performed in the electrical fabrication shop.
Welding was to electrical supports as detailed in design specification E-1406/28 and weld request fl087. The inspector also verified that weldor was properly qualified.
No items of noncompliance were identified.
