Inservice Inspection and Test Programs (Unit 1)
The inspector met with the licensee's inservice inspection and test coord-inator to discuss the status of the ASME b&PV Code Section XI Programs.
The Inservice Inspection Program for Welds and Components has been drafted l
by tr.e licensee.
The final program will be finalized as soon as the unit l
achieves commercial operation status, which will establish the edition of I
l

.
.
.
Section XI which applies. The licensee will have the program finalized and submitted by the June 30, 1983 date stipulated in the operating license.
The Inservice Test Program for Pumps and Valves was submitted earlier for review and approval, but the baseline testing being done as systems are put into service is also being used to de-bug the test program. The licensee is preparing a revision to the program which will reflect the as-built plant conditions and the license Technical Specification surveillance require-ments.
There were no violations or deviations discovered during this phase of the inspection.
6.
Potential Reportable Deficiencies (PRD) (10 CFR 50.55(e))
The inspector reviewed the status of the following PRD Reports:
a.
(Closed) PRD 82-30 Error in Bechtel's Jet Impingement Analysis. The i
inspector reviewed the licensee's letter AECM 82/287 dated 6/21/82 and the supporting documentation which reported that the extent of the problem had been identified and that corrective action had been completed. This item is closed.
b.
(0 pen) PRD 81-44 Seismic Adequacy of Bettis Air Actuators Furnished with Certain Henry Pratt Butterfly Valves.
See item c. below.
c.
(0 pen) PRD 82-32 Yoke Failures on Bettis Actuators on 24" Henry Pratt Butterfly Valves. The inspector reviewed the licensee's file on PRD
'
81-44 (noting that the licensee had determined that the problem of Seismic Adequacy had been determined to be not reportable under 10 CFR
.
50.55(e)). The problem described in PRD 81-44 was compared with the I
problem identified in PRD 82-32, (which the licensee determined to be reportable).
The licensee was asked to show why PRD 81-44 and PRD 82-32 were l
separate problems. After some discussion with the licensee's QA and maintenance engineering personnel, it became apparent that the major
'
difference was that 81-44 was being tracked by construction and 82-32
.
by maintenance engineering. After the discussions showed that some of
'
the same valves were involved in both PRD's, the licensee agreed to re-evaluate the reportability of PRD 81-44 and to discuss the relation-ship of PRD 81-44 to PRD 82-32 in both final reports.
l There were no violations of deviations discovered during this phase of the inspection.

Strel Structures and Supports-Observation of Welding Within Containment (Unit 2)
The inspector observed welding activities in the suppression pool and in the drywell. The welding observed was as follows.
a.
Suppression Pool - Chicago Bridge and Iron (CBI) was in the process of installing the stainless steel liner plate in the floor of the suppression pool.
The inspector observed welding of floor plates to imbedments and the splicing of floor plates by welding on addi-tional material with full penetration welds.
(The splices were necessary because several of the imbedments were found to be mislo-cated.) The inspector observed the Air-arc gouging of the back side of the full penetration splice weld, the grinding of the gouged area, and the welding of the root pass on the second side. Discussions with the welding personnel and observation of their work provided assurance that they were familiar with the welding procedure and quality assur-ance requirements for the work in progress, b.
Dry-Well Structural Steel - The licensee is in the process of strength-ening the installed structural steel by welding doubler plates to the flanges of the beams. The welding is being done in accordance with AWS D1.1 using Bechtel structural welding procedures.
,
The inspector observed the fit-up installation, tack-welding, pre-heating, and final welding of various doubler plates. The observation included discussions with the welders and supervisors as to what the
'
job requirements were. The responses received reflected awareness of job quality and procedure requirements.
There were no violations or deviations discovered during this phase of the
!
inspection.
'
Safety Related Piping - Observation of Work and Work Activities (Unit 2)
The inspector observed the placing of main steam relief spargers in the suppression pool. The spargers had been in outside storage and were beino lifted over the containment wall and lowered into the suppression pool area.
,
l
'
The inspector observed the handling of the spargers after they had been set inside as well as the lif ting operation.
The lif ting and handling gear appeared to be in good condition and the personnel involved were
being careful not to damage any of the previously installed equipment.
,
There were no violations or deviations during this part of the inspection.
l 9.
Review of Project Schedule (Unit 2)
The inspector reviewed the status of the Unit 2 project with the licensee's Project Manager, Mr. T. H. Cloninger.

The licensee has determined that the most cost effective method of' pre-
+
r serving the major equipment. is to complete the Unit 2' buildings and store the items in place. The licensee stated that the priority work items for
+
'
the near term on Unit 2 would be the closing of the buildings and the work
in areas shared with Unit 1 in order to strengthen the Unit 1 security.

There were no violations or deviations during this phase of the inspection.
