Facility Tour Work in progress, completed work, and plant status in several areas were ob-served during a general inspection of both units. Work items were examined for obvious defects or noncompliance with NRC requirements or licensee com-mitments. Craft and supervisory personnel encountered in work areas were interviewed. No unacceptable conditions were identified.
3.
Licensee Action on Previous Inspection Findings (Closed) Noncompliance (387/79-14-03): Failure to specify supplementary essen-tial variables in welding procedures. This item was reviewed during inspection 387/81-17 and remained open pending GE audit of welding procedures. The check list for control of special processes of GE audit of April 5,1979 includes review of welding procedures. The welding procedures in question had been revised and the revisions had been reviewed by an NRC inspector during the previous inspection.

(Closed). Noncompliance (387/80-06-01): Measurement of slope of instrument tubing. The inspector examined NCR's No. 5617 and 6555. All lines had been reinspected and reworked as necessary. The inspector also examined Bechtel memo dated August 12, 1980 concerning the method of verifying slope of tubing and records of training for such inspection.
(Closed) Noncompliance (387/80-25-01, 388/80-16-01):
Inadequate inspection procedures and inspections of grouting equipment base plates. The inspector examined the documentation listed below and discussed corrective actions taken with the licensee.
Corrective actions included recheck of all box type equipment bases for grout voids, mapping the indicated voids, review of proposed method of grouting with General Electric Company,and the equipment vendors, and grouting of the voids.
In addition to inspection of the work by Bechtel QC, the licensees Construction Surveillance Group had performed surveillance inspections to verify implementa-tion of the grouting.
Documents examined included:
Field Procedure FP-C-4 which had been revised to include grouting of base
-
plates; QC1 C-1.10 which includes requirements for grouting inspection;
-
NCR No. 6836 which documents inspections and grouting of voids; and
-
Special Surveillance Instruction SS1-81-15 for surveillance inspection of
-
the grouting and records of the inspections.
(Closed) Noncompliance (387/81-08-12, 388/81-04-09): Routing of sample return i
line for Hydrogen Analyzer (HA).
Clarification of the requirement that the I
return line not be run vertically more than 30 feet had been obtained from the manufacturer. This requirement was intended to prevent trapping of condensa-tion on the line and had been revised to state,"The sample return line to the containment should not be run vertically upward more than a total of 30 feet."
The inspector examined Dwgs. HCB 122, 124, 109, 108, and 123, and Dwgs. SP HCB 108-1, 2, and 3.
The HA lines shown met the manufacturers instructions since the only return line exceeding 30 feet was run in a downward direction. The in-spector noted that vertical return down lines were heat traced to prevent con-densation.
(Closed) Noncompliance (387/81-12-01, 388/81-06-01):
Failure to meet 1-inch
,
j separation requirements for conduit / raceway.

The inspector examined NCR's No. 7706 and 7954 which showed that the necessary rework had been completed in order to prcvide the required separation. The
inspector discussed this problem with the licensee, particularly with respect to additional discrepancies of this nature. The licensee stated that this type of problem generally resulted from perfomance of "non-Q" work in the area after inspection of the "Q" listed work was completed.
In order to identify such con-
,
ditions,QCl E-3.0 for final inspection prior to room turnover from construction i
to operations, included a requirement for inspection of conduit / raceway separa-i tion.
The inspector observed the rework condition of selected conduits and noted that
,
j the required minimum 1-inch separation had been provided.
In one case, conduit.
EM-055.which had been designated as a " spare",had later been redesignated as
!
IMG028 into junction box JB4200 and did not have the' required separation from
.
elk 335. However, these conditions:had been identified by the licensee on NCR No. 8669. The inspector had no further questions concerning this item.
,
i (Closed) Unresolved Item (387/81-12-02, 388/81-06-02): Ground cable installed
~
within 1-inch separation ' area between conduit / raceway. The licensee has deter-
mined that the separation was required to prevent spread of flames and, there-
,
fore, the presence of the ground cable does not have any adverse effect on separation.
i (Closed) Unresolved Item (387/81-17-01, 388/81-09-01): Construction Surveillance
,
I Group inspection reports. The licensee has issued a memo dated September 3, L
1981, " Completion of Construction Surveillance Reports (CSR)," issued construc-l tion surveillance instruction PL-E-6.0, Revision 2, and conducted a training ses-I sion on completion.of CSR's.
(Closed) Inspector Follow Item (388/78-20-02): Closeout of NCR No. 3237.- This i
NCR has been resolved.
In addition, the qualification of Westinghouse penetra-l tions'was reviewed and revised for Unit 1 during inspection 387/81-26.
i (Closed) Inspector Follow Item (387/78-99-12): Plate to wall tolerance. The
inspector observed installation of selected hanger brackets and noted plate to
'
wall tolerances. No items of noncompliance were identified.
(Closed) Noncompliance (388/81-01-03): Failure to follow procedures-for inspec-tion of specialisted terminations. The inspector examined NCR No. 6992, which
identified rework and closed out the item concerning the cable termination which
'
had not been inspected, and NCR No. 7137, which closed out the item concerning
.
the other identified terminations. The licensee also reinspected all other
-
accessible Burndy Cable Connectors which showed discrepancies in documentation t
l of the previos inspection. This reinspection was witnessed by PP&L NQA and is
documented on QA Audit dated 3/31-4/8/81. Discrepant conditions identified during the audit were added to and resolved with NCR 7137. However, no unaccept-able cable terminations were identified. The inspector also observed termina-
.'
tions which had been prepared for training of inspectors prior to reinspection of the terminations and examined training records The inspector had no further
_
questions.concerning this item.

(0 pen)UnresolvedItem(387/79-41-03):
Protecticn of mechanical snubbers.
The inspector examined NCR 4989, Deficiency Report No. 0103, Quality Action Request (QAR) F-713, Bechtel letter QAL-904,and PP&L letter PLB-ll562.
These documents and disucssions with licensee personnel showed that the shock absorbers identified by the NRC inspector had been inspected for external dam-age and covered for protection; a number of other snubbers had been found unprotected; requirements for protection of snubbers had been established; and storage conditions of snubbers had been included in the daily walk through surveillance inspection by the storage and maintenance group. The corrective actions had been verified by PP&L NQA.
The inspector made a spot check of snubbers to observe their storage conditions.
Of approximately 50 snubbers observed in Units 1 and 2, three were found to be unprotected (f;o. GBB-115-H-15, HBB-118-H-18, and HBB-118-H-22).
In addition, 2 snubbers which were surplus,were onsite and unprotected (DBC-101-H-16 and DCA-111-H-28). This item remains unresolved pending improvement in storage and surveillance inspection by the licensee and further inspection of these conditions by an NRC inspector.
(0 pen) Unre. solved Item (387/81-01-03):
Requirement for electrical separation criteria external to panels and/or equipment.
Bechtel QA has requested sep-aration criteria from San Francisco by QAR-F-772.
This item remains unresolved pending establishment of these criteria, inspection by QA_and review of the results by an NRC inspector.
(Closed) Unresolved Item (387/80-18-01, 388/80-12-01): Licensee actions and response to NRC Bulletins and Circulars.
During a number of inspections in late 1980 and throughout 1981, the inspector reviewed the licensees activities and corrective actions in response to Bulletins and Circulars. The inspector determined that the Bulletins and Circulars were forwarded to appropriate per-sonnel for information and action, that responses to Bulletins were properly submitted to NRC, that reviews and evaluations were supported by records, that a record of nonconforming items was maintained in order to avoid future orders of such items and that corrective actions were taken as required.

QA Records for Main Steam Isolation Valves (MSIVs)
The inspector discussed several questions concerning repair welding and post weld heat treatment of the castings for the MSIVs with the licensee. The castings were furnished by Quaker Alloy Casting Company (QAC) to the valve manufacturer Atwood Morrill Company (AMC) for supply to the site by General Electric Company.
Certain problems had been identified with similar valves from the same supplier at another site.
The licensee had been informed of these problems and had identified them on NCR No. 8563. An investigation is now in progress to determine whether the valves at SSES are similarly affected. The inspector was informed that these valves were fabricated to ASME B&PV Code,Section III, Sumer 1971, and he was furnished the following information concerning the identified problems.
a.
PWHT heating and cooling rates.
During heat treatment the heating rate exceeded code requirements. However, during the final heat treatment following rework the heating was perfomed at an acceptable rate but data is not available to detemine the rate of cooling.
Investigation is still in progress.
b.
NDE to be perfomed after final heat treatment.
Records show that this requirement was met, c.
Performance of Surface NDE after repair excavation and prior to repair welding.
Records show tilat this requirement was met.
d.
Welding to be performed after normalizing and tempering. Records show that this requirement was met, e.
Qualification of Quaker Alloy Procedure.
Procedure was qualified for 1240-12600F. The maximum temperature reached during heat traatment was approximately 13500F. Maximum temperature during final heat treat-ment was approximately 11500F. This investigation is still in progress.
This item is unresolved pending completion of the licensee's investigation and review of the records by an NRC inspector.
