Follow-up on Regional Requests This ef fort was to include a review of the QA records for final setting of the Service Water Pumps, and to review the detailed installation removal requirements of the containment spray pumps, the residual beat (RHR) pumps, and the high pressure safety injection pumps and to confirm their proper installation by review of the QA records.
The following documents were reviewed to determine the licensee's connitments and QA/QC requirements for the installation of these pumps:
SCE&G Field QC Procedure 6.2.1, " Inspection of Alignment of Rotating Equipment" SCE&G Field QC Procedure 6.2.2, " Installation of Rotating Equip-sent" DCC Construction Procedure AP-Vill-03 RS, " Cleaning, Handling and Preservation", and Exhibit A, " Plant Equipment Maintenance Log" a.

The SCE&G audits of Goulds Pumps were reviewed in File 301.1.7,
" Surveillance and Audits". These were the pre-award of contract QA audits of the vendor on December 10 and 11,1974, and February 12 and 13, 1975, and a pre-shipping of pumps audit inspection of June 29 and 30, 1977.
All findings were dispositioned in a timely, adequate manner.
The installation of the three service water pumps was inspected in the service water pump bouse. These pumps are identified as
,XPP-39A, B and C - SW.
Some discharge piping is connected to the pump bowls, but the discharge header is disassembled and awaiting the backfilling of the lines outside the pump bouse structure.
The pump r. tors are not mounted on the pumps and final alignment and grouting of the pumps is yet to be accomplished. Nonconforming Condition Notice (NCN) 0527 dated October 24, 1978, concerning the three pumps' discharge flange connections was reviewed.
Actions are being taken to resolve this open NCN.
No items of noncompliance were identified.

Installation of these pumps has one coritainment spray and one RHR l
pump in a room; the other one of each pump is in an adjacent l
room.
Inspection was made of the installation of RER pumps XPP 31B RH and XPP 31A RH. Both pumps are mounted and grouted with suction and discharge lines attached. The drive motors are not installed.
The licensee stated that preliminary aligenent is completed, but final alignment and setting will follow the disposition of out-standing NCN's 423M, 476M and 472M. These WCN'c were reviewed and action by the licensee is adequate and timely.

RII Report No. 50-395/78-26 I-5 The installation of the containment spray pumps XPP 38A SP and XPP 38B SP was inspected.
These pumps and their speed reducers and motors have had preliminary alignment settings, but are not coupled together. The licensee stated that final alignment and setting will be done after disposition of outstanding NCN's 554M, 476M, 552M, 554M and DN's 1710M and 1375M. The NCN'. and DN's were reviewed and f ound to be current with adequate and timely disposition actions.
File 307 SP XPP 38A was reviewed and contained " Check Form for Mechanical Vessels", dated May 27, 1978, which verified center-
. lines and elevations of the pump installation, and the FQC Form 6.2.2-1,
" Inspection of Installation of Equipment", dated
' September 11, 1978, certifying status of installation and referencing applicable NCN's and DN's.
File 307 SP XPP 3oB was reviewed and contained comparable data for that pump installation.

High Pressure Safety Injection Pumps c.
The following gal drawings were reviewed and used to verify locations, orientation details and installation requirements of
,
the safety injection pumps XPP 0043A, B and C.
E-412-101, " Auxiliary Building - 2nd Basement Floor - Eleva-tion 388'-0" - North Concrete Outline" E-412-109, " Auxiliary Buildinc - 2nd Basement Floor - Eleva-tion 388'-0" - Sections" The installation of the three pumps was inspected.
The units were grouted-in, pipe installation was incomplete and the couplings between the motor and the speed reducer and between the speed reducer and the pump were not installed. DN 1268M relating to a flanged joint fit-up on the "C" pump is outstanding and is being dispositioned.
File 307 CS XPP0043A, " Charging /Saf ety inspe'etion Pump A", was reviewed and included the " Inspection of Installation of Tanks, Vessels, Heat Exchanges", FQC Form 6.2.2-1, dated May 10, 1977, which certified the pump's proper location, both centerlines and elevation.
File 307 CS XPP0043B contained similar documentation for the B pump.
File 307 CS XPP0043C indicated preliminary settings on " Check Form for Mechanical Vessels".
The licensee's representative stated final setting certification is pending the resolution of DN 1268M.

Independent Inspection Effort Welder Qualification and Training Program a.
The QA/QC procedures used to indoctrinate, qualify, and train newly hired and other project personnel within the welding disci-pline are as follows:
-
" Orientation, Introduction, and Training of AP-II-05 R6
-
Personnel
" Qualification of Welding Procedures and Welders" QCP-II-01 R6
-
.
" Qualification of Welding Procedures and Welders" WE-II-01
-
In addition DCC has written specific instructions to be used in the welder upgrading program, i.e. upgrading from carbon steel plate welding to X-Ray Pipe Welding.
DCC stated that although the program for training and upgrading welders bas been in existence f-some time, it had never been documented until now.
Basically personnel with previous welding experience may take the standard performance quslification test as prescribed in Section IX, 1974 Edition of the ASMI Code.
Those with no experience are given the opportunity to practice until supervision is satisfied that the required level of expertise for qualification has been attained; DCC stated tbat this usually takes between six to eight weeks.
Those candidates without experi,ence receive oral and practical welder training at the training facilities located outside the gate where no testing is performed.
All perf ormance qualification tests are conducted inside the gate at the test shop.
Qualified project welders who demonstrate good ability and

In order to upgrade for X-Ray pipe welding, a qualified welder must weld 3 acceptable thin wall sockups conse-cutively and 2 acceptable heavy wall mockups consecutively for each material to be upgraded.
In addition,. welders who have upgraded to, but have not worked on X-Ray quality welds for a period of two weeks or more, are required to practice on a mock-up in the test shop prior to welding in the field.
This program has been in existence, although not documented, for approximately one Fresently there are about 33 to 35 welders qualified and year.

The inspectors reviewed the personnel and performance qualifica-tion records of approximately 20 X-Ray qualified welders; observed welders practicing and upgrading in the test shop; audited the welder training presentation designed to familiarize new personnel with weld material control, QA practices, wel test shop rules and regulations, shop safety and welder testing procedures; and reviewed welder performance (rejection rate) records.
b.
Observation of Field Welding Activities Fabrication, inspection and testing of field welds, within the reactor coolant pressure boundary and safety related systems, is controlled by Section III,1971 Edition through the summer 1973 addenda of the ASME Cote.
