S&L further established g requirement of 2 x 10 rads for the Standby Gas System and 1 x 10 rads for the Control room system.
These requirements must be met by American Filter Co. and
,
Zack Co., who should submit qualification information in gaskets to be used in the above systems.
(Closed) Unresolved Item (461/78-06-01) Safety related Burady/ Husky straight cable tray resistance welds were not being touched up with a zine rich paint.
The inspector reviewed an interoffice memo (DES 35-79), dated May 1, 1979, subject:
" Cable Tray Installation Spot Weld Touch-up" which stated that "...all spot welds on Husky furnished cable trays, installed as safety related, shall be touched-up with a zine rich paint as specified in K-2999 form 1895-E."
Also, Baldwin Associate Supplier Quality Control Activity Report No. C8204.8, dated May 3, 1979, item 3.b specifies galvanized touch-up per S&L specification K-2980 Form 1895C paragraph 2.5.1 riel used by

In addition, S&L cable tray specification K2980 article 301.13 was amended to require touch-up of tray with zine rich paint at the vendor for all future orders.
(Closed) Unresolved Item (461/79-01-04) Calibration Procedure No.008 specified 150 to 350 F temperature for the weld rod hold ovens.
The inspector reviewed revision 3 dated May 10, 1979 to Procedure No. 008 that changed the minimum and maximum temperature to 250 F and 450 F per BTS-402 as required by the AWS.
(Closed) Qualification Papers for L2KDE Inspector (461/79-04-01)
During the last inspection, an inspector for Reactor Controls, Inc.
did not have his qualification record onsite. The inspector verified during this inspection, that his papers were in order and onsite.

Functional Areas Inspected 1.
Replacement Program For Recirculation Inlet Nozzle Safe Ends Fitup or welding is underway on 8 of the 10 safe ends. Eight of the 10 thermal sleeves which will attach the safe ends to the inlet pipes for the jet pumps are onsite.
Outboard end is prepped for welding but the other end is not so that the proper length can be established prior to prepping the inboard end.
The following Product Quality Certification (PQC'S) were examined.

No item of noncompliance or deviations were identified.
2.
Feed Water Safe Ends and Control Rod Return Line Cap Four feedwater safe-ends were received in PQC-EE-339. These
-
were manufactured by Chicago Bridge & Iron Nuclear (CBIN) and two deviations were identified and accepted by the customer.
These were made of carbon steel to specification SA-508 class 1 and were buttered with inconel on one end and stainless steel on the other.
No radiography of finished welds had been made.
ASME Section III, 1974 edition, summer 1976 addenda is applicable to these safe ends.
The Control Rod Drive (CRD) return line cap is an inconel forging received on PQC-BB685. This material was procured to SB-166, Grade 600 and was manufactured by Coulter Steel Co.
ASMI Code Section III, 1974 edition, winter 1975 addenda is applicable to this part.
No items of noncompliance or deviations were identified.
3.
Safety Relief Valve (SRV) quenchers Drawing No. M27-1000-OlA Rev A was examined and indicates the 16SRV quenchers will be distributed 4 per quadrant. Each quencher will have 4 cross arms which will be about 5 feet above the suppression pool floor. While bracing will be to the floor, the materials or details of the bracing was not availatie.
This area will be examined on a future inspection.
Tne inspector en a previous inspection had noted considerable water on the tuppression pool floor under the protective layer of plywood.
The licensee has taken action to inspect the stainless steel floor and sample the water on a monthly basis.
Bal(win QC and the Central Lab are responsible for this activity, which should minimize any pitting problems.
No items of noncompliance or deviations were identified.
4.
Bio Shield Steel Welds Radiography The inside horizontal ring 1 to ring 2, identification M27RS591H has a weld about 1" thick. The inspector examined-5-424 148
.
.
12 radiographs which had an unground surface. The roughness and space between passes in some cases made evaluation difficult.
Close visual inspection together with the radiographs is necessary for evaluation. This weld was radiographed 100%. Identification M27RS61 weld was required to have a magnetic particle inspection of each layer. This was done to specification, VST-MTC-1 Rev 3 using a Model Y-6, SN111 equipment with 4" to 6" prod spacing. This weld was made to the requirements of
,
ASME Section III 1974 edition, 1975 addenda, paragraph NB5000.
Two Baldwin welding procedures N588-588-BA-L Rev 0 and N588-588-F-L are used to weld this structure.
N-588-588-F-L is qualified to Section IX for groove, socket and fillet welds in 588-C steel materials, Flux cored are welding (FCAW) shall be used for all layers when using a backing ring or strip.
Base filter r2re shall be to SFA5.20 and/or 5.20-69 or E70T-1.
The protective gas shall be welding grade Argon 75% and carbon dioxide 25% at a minimum flow of 35CFH. The N588-588--BAL-L is qualified for usage of GTAW and/or SMAW.
No items of noncompliance or deviations were identified.

1.
Weld Material Control The inspector reviewed weld material control as a result of two allegations tha' were made by a former emnloyee of Baldwin Associates Technical Services. The allegations are concerned with (1) issue of weld fillter material to nonqualified welders and (2) destroying weld rod issue slips.
The inspector reviewed records and interviewed personnel as follows:
a.
Randomly selected forty two (42) welders names and I.D.
numbers from " Weld Material Field Requistions" (Form BTS 030) located in the four " Weld Material Field Control Centers" and verified that all welders were qualified.
b.
Randomly selected five travelers from the records storage area. These travelers contained the welders I.D. and the serial numbers of the weld material field requisitions that identify the welder and the weld material used for a specific weld.
Following is a list of travelers selected.
(1) F-ISX-029-0105 (2) F-ISX-03BA30-C (3) F-ISX-BA30-E (4) F-ISX-03BB30 (5) F-ISX-10AA18-B Twenty three weld material field requisition numbers were randomly selected from the above travelers. The requisi-tions ranged in dates from September 1977 through February 1979. All were on file with the exception of one, (S/N A 0000-19047). The inspector verified that the welders name and I.D. corresponded to that on the traveller and further verified that the welders were qualified at the time the welding was performed.

d.
Discussion with the Manager, Technical Services.
e.
Interview of the individual substituting in the weld material control center.
,
Comment, discussion and interviews established that in the event that a welder is absent from work or for some reason he did not pick up his assigned weld rod the weld rod was returned to the hold oven and the weld material field requisition was destroyed. Also, through discussion and reviewing welder qualification records, it was learned that many carpenters, electricians, pipe fitters and steel workers had been qualified to weld. This could pcssibly explain the allegations.

No items ofnoncompliance or deviations were noted in this area of the inspection.
