Licensee's Action en Previous Inspection Findings (0 pen) Infraction (50-352/79-12-04): Incorrect Pipe Support Pin Material (Reference: Report 50-352/80-01) Visual and metal hardness tests were performed on a total of 97 pipe sup-port pins. All pins indicated hardness values consistent with A-193 material , and no abnormal physical characteristics were noted. The sampling was t performed on elevations 177', 201', 217' and 253'. This item remains open ' per ding completion of the licensee's program and review by the NRC.
(0 pen) Unresolved Item (50-352/80-05-01): Water Quenching Stainless Steel Welds The licensee revised Job Rule G-16, paragraph 10, to provide instructions ', for water quenching stainless steel and for the testing of th,g water supply for chlorides. However, the imposed chloride limits of 200 PEk exceed the recommendedvaluesofRegulatoryGuide1.37,ANSIStandardN45.2.1,an,gthe requirementsofBechtelSpecificationP-303, paragraph 3.32,of100PRh.
This item remains open pending revision of the limits to acceptable values.
(0 pen) Infraction (50-352/80-12-13): Unauthorized {{pidsoContainment Liner A review of licensee corrective action disclosed that the visual examina-tion was not properly documented.
In addition, the original containment repair procedures for similar temporary attachments indicate the need for vacuum box testing of the repairs.
This item remains open pending documentation of the visual examination and verification of the necessity for vacuum box testing.
(0 pen) Noncompliance-(50-352/80-12-14): Improperly Qualified Receipt Inspector Schneider, Incorporated, the heating, ventilation and air conditioning (HVAC) subcontractor, employed a receipt inspector who was not properly qualified.
The licensee reinspected the work performed by this inspector and revised the Project Procedure, PPM 5.1 to provide three different categories of
inspectors.
, .,,,. , - - -.. ~--
. .
. At the time of this inspection, the individual identified as unqualified no longer was employed by Schneider, Incorporated.. Examination of Project Procedure,' PPM 5.1 verified that three categories of inspectors were established (Receipt, Welding, and Installation). A sampling of inspector qualification records. verified that the procedure's new requirements hava j been implemented.
The inspector also reviewed some of the receipt inspec-l tions performed by the unqualified inspector and verified that they were i reinspected.
l (Closed) Noncompliance (50-352/80-12-15): Control of Welding Rod Oven ! Temperature .i ! The licensee issued Corrective Action Report No. 43 which directed replace-l ment of the defective ther=ometers with new, calibrated thermometers. The ! inspector reviewed the Corrective Action Report No. 43, Project Procedure ! ' PPF3.8,"geldMaterialControl",andmeasuredthetemperatureofrodovens Nos. 1, 2 and 3.
He verified that the oven temperatures were yithin the t specified ranges prescribed in Project Procedure PPM 3.8.
x (Closed) Noncompliance (50-352/80-12-16): Failure to Perform Audits The licensee performed an audit of the cited area on August 13, 1980, and issued a formal audit schedule. The inspector examined the audits conducted on April 29, August 15, and December 3, 1980, and verified that all areas of the quality assurance program have been audited.
He also examined a
memorandum, dated December 22, 1930, promulgating the current audit schedule.
) (Closed) Inspector Folleg-Up Item (50-352/8G-18): ) GE I & SE configuration checks tave been terminated and there are no - current plans to perform these checks in the future.
The audit schedule has included audits of GE-NEEG.
The inspector -
reviewed the licensee's audit of GE-NEEG, Audit Report No. 231, dated December 9-11, 1980, and verified that the audit has been conducted.
) - (0 pen) Unresolved Item (50-352/81-01-06): Control of GE-FDDRs ! Further examination of FDDR control' has disclosed that FDDR No. HH1-325 was , dispositioned without issuing a design control docu=ent such as a Supplier l Deviation Disposition Request, a Field Change Request, or a Field Modifica-l tion Control. This matter is also considered unresolved pending determination
that- . t (1) a design change did take place;
(2) the design change was the responsiblity of Bechtel Engineering; and, (3) the proper document for controlling the design change.

Heating, Ventilation and Air Conditioning (HVAC) Subcontractor Audit The inspector performed an audit of selected portions of the HVAC sub-contractor's quality assurance program to verify the implementation of the quality assurance manual provisions.
The following areas were ex-amined: the approved vendor's list and its use; design document con-trol; site quality control inspections, internal audits; inspector quali-fication; weld material control; and organizational staffing.
The review of the site inspection program disclosed that, although properly documented, there is no po itive method employed to ascertain the status p of in process inspection for welding.
The Quality Control Site Inspection Report only briefly describes the field welds that have been in process inspected and accepted. The Project Procedure, PPM 5.3, requires that 100% inspection of in process welds be performed. Without a mapping or tracking p' system, it will be extremely difficult to ascertain that 100% of the welds have been inspected.
In addition, Attachment 3.9 to PPM 5.3 requires 10% random nondestructive testing for ASME Code welds. Again, there is no positive method for determining the total population.
This item is con-sidered unresolved pending review by the licensee and implementation of positive controls. (50-352/81-02-01) h The inspector examined the internal seal welds for the partially completed duct work No. M1097.
These welds are described on Drawing No. C-1350, Section A1.
It was noted that the welds did not match the configuration shown on the drawing in that they were much wider than specified.
Further investigation disclosed that this condition had been identified by the licensee's quality control program on Nonconformance. Report No. 422, dated November 4, 1980.
No items of noncompliance were identified.
5.
Electrical Raceway Inspection Reviewed the Specification Drawing E-1406, " Conduit and Cable Trays Notes, Symbols, and Details"; Job Rule E-2, " Electrical Field Raceway Reporting System"; Quality Control Instruction E-2.0, " Installation of Exposed Race-way"; and " Specification for Cable Tray", E-49.
The inspector selected cable tray No. IBTLA, and the partially com-leted conduit installations, Nos. 1ZZ231 and 1ZZ412, for a visual examinat'on.
The examination verified that selected portions of the installations conform to the details of Drawing E-1406. The inspection included various aspects of design, in- ' stallation, and quality control inspection.
No items of noncompliance were identified.

Shroud Relocation The Unit No. I reactor shroud was relocated from the repair / storage area to the refueling room.
The inspector reviewed the " Shroud Transporting and Lifting Procedure for RPV Internals", and observed the lifting and-transporting operations. He verified that adequate. measures had been taken to prevent damage to the shroud during movement.
No items of noncompliance were identified.
7.
Residual Heat Remova? System Ccnfiguration Inspection The inspector performed a piping and equipment verification inspection of the Unit No.1, Residual Heat Removal System outside of containment.
He verified that the flow paths, as depicted on P & ID M-51, Sheets 1 and 2, are as described. This was performed only for the major flow paths and components.
No deviations were,oted.
8.
Observation of Pipe Welding Observed the weld build-up for dimensional correction on the 24" diameter, Schedule 1.812", pipe weld and preparation, D88-104-1-2 FW 51.
Verified that the appropriate welding procedure was being used, the welders quali-fication, and that the appropriate ASME Code requirements were being spect- . fied.
No items of noncompliance were identified.
9.
Unresolved Items Unresolved items are matters about which additional information is needed to ascertain if the item is a noncompliance, a deviation, or acceptable.
An unresolved item is discussed in paragraph 4.
10.
Exit Interviews Exit interviews were held with members of the licensee's staff, denoted in paragraph 1, on February 12 and 26, 1981.
The inspector discussed the scope and findings of the inspection.
