This procedure addresses 2-inch anchor bolts only for both Containment interior installations which address Bostrom-Bergen Metal Products and Southern Bolt, 2-inch bolts only through elevation 860 feet only. All Bostrom-Bergen 2-inch anchor bolts and nuts will be color coded white.

A 2-inch wide band will be painted on all A540 bolts at the end of the threads on one end. The heat numbers of all 2-inch A540 bolts received are as follows:

sn 545, 969, 035, 055 inch White Band The A540 nuts from Bostrom-Bergen will have three flats on the nuts painted white. The heat numbers of all A540 nuts received are as fol-lows:

840, 260, 458, 655, 073 - Three Flats Painted White All 2-inch plates on the site that are from Bostrom-Bergen and Southern Bolt is 583 plate and are, therefore, interchangeable. These plates will not be color coded.

A540 bolts and nuts will not be tack welded as in the past.

Instead, U-bolts will be used to jam the 588 plates up to the AS40 nut. Refer to GHF-1789, dated July 15, 1977. During installation, AS40 bolts will have an A540 nut both color coded white with a 588 plate, which is not color coded (white bolt to white nut).

Southern Bolt has furnished two thousand (2000) 2-inch A320 anchor bolts with 194 nuts and 588 2-inch plates. The A320 bolts will have a 2-inch wide green band painted at the end of the threads on the long threaded

.l end. The 194 nuts will have three flats painted green. Heat numbers for i

A320 bolts are as follows:

l l

SA99GG1038, SA86GG853, SA90GG907, SA87GG910, i

194 Nuts - Heat numbers are as follows:

/

X21 and X9 - Three Flats Painted Green All A320 bolts will use the jam nut method to hold the 588 plate to the nut. On all A320 bolts only the jam nut method will be used during in-stallation.

Each assembly will consist only of A320 bolts with 194 green nuts, (the green nuts being located on the end side of the 588 plate).

A red painted jam nut will be used on the inside o.f the 588 plate. No welding or U-bolts will be used on the A320 bolts - jam nuts and 194 outside nuts only.

The control during installation will be that only white bolts with white nuts of the 540 will be used.

U-bolt securing of the 588 plate to the nut is the only method to be used.

Only the A320 bolt painted green will have a red color coded jam nut with a 588 plate and a 194 nut colored green will be used. No welding or U-bolts will be used.

The craft foreman in charge of installing these 2-inch bolts will person-ally insoect each bolt after installation to verify all bolts are install-ed per white to white, color matching, all plates are secure and the bolt orocerly secured. The foreman will verify that green bolts, red jam nuts, 588 plate and green nut are used together.

He will see and inspect the green color coded bolts to see that all plates are secure, that colors correspond and that all bolts are secure.

Brown & Root Construction will notify B&R OA/0C (by AVO) each time two complete rows of bolts, nuts and plates are completed so the QA/QC can do their mapping recuirements.

All color coding will be done in the warehouse prior to issuing to the field except those already installed in the Containment Number 1 forms and resteel. All heat numbers on all nuts will be highlighted so that QA/QC can readily identify.

All supervisors are to read and fully understand these instructions prior to beginning bolt installation.

COMANCHE PEAK STEAM ELECTRIC STATION 1980-82 2300 MW INSTALLATION ENGINEERING REVIEW AND METALLURGICAL ASPECTS OF TACK WELDING OF BOLTS REF: NCR #704 AND #722 I.

THE PROBLEM NCR M-704 and NCR M-722 address the welding of bolt, nut and anchor plate material combinations that were not in conformity with the engineering specification.

These non-conformities have been evaluated by the writers and they have concluded that the bolt asse=blies used "as-is" will perform in accordance with the engineers design re-

?

quire ents.

A.

Metallurcical Aspects NLY Tach welding has been performed on pipe whip restraint bolts to nuts of various compositions.

The nuts in turn have been tack welded to ASTM A-588 plate, a low alloy plate cuitable for welding.

The concern is that the cetallurgical combinations are compatible and have been welded using acceptable filler material and cost importantly acceptable welding procedures.

So=e com-positions were welded by a qualified procedure (Brown

& Roet WPS-10043) established before the field welding was performed.

Other compositions were field welded and later qualified (Brown & Root WPS-10050).

B.

Structural Asoects The essential purpose of the nut to Solt and nut to anchor plate tack welds is to hold the assembled parts firmly in place until they have been cast in concrete.

In addition, the nut to bolt tack welds serve to pre-vent accidental turning of the bolt with respect to the nut during installation of the pipe whip restraints that are to be attached after the bolts have been set in concrete.

II.

DETAILS OF WELDED PAIRS The bolt and nut combinations involved are listed below r.isa,o a

Low-hydrogen electrodes, such as E7018, are recoc= ended for use with these steels in shielded metal arc (SMA) welding.

The use of pre-heating and an elevated interpass temperature are essential to minimize hardening of these compositions on cooling.

IV.

WELD PROCEDURE SPECIFICATIONS 10043 AMD 10050 - BROWN & ROOT These procedures demonstrate that the compositions used for bolts and nuts were welded with E7018 weld rod with 200 F pre-heat and 200-500 F interpass temperature and passed the macroetch test require =ents of AUS Dl.l.

V.

EXAMINATION OF FIELD WELDS i

Brown & Root c:<aminations of the field welds indicated sat-isfactory welds as examined visually.

Furthur, on 8/2/77, R. E. McGrane and G.

-q p x g - 7 w w' ff y O Y ATTACKMENT TO DC/DDA-57 PAGE 4 OF 5 I

Stern, accompanied by R. C. Barber examined approximately 70 random nut to bolt welds and saw no evidence of cracks.

VI.

CONCLUSIONS A.

The metallurgical co= positions involved in the nuts and bolts that were tack welded are amenable to welding by the procedures followed.

The qualifications WPS-10043 and 10050, establish the weldability of these compositions under the conditions used.* Visual examinations of the field welds reveal no significant defects.

The procedures used eliminate the possibility of excessive hardening on cooling from weld metal temperatures and heat affected zone temperatures.

These welds are considered satisfac-tory.

B.

The nut to bolt tack weld is made at the top of the nut.

The heat affected zone is in an area not subject to s tres sing.

The nut to anchor plate tack weld is in a location that will not impair the ability of the nut to bear against the plate and transfer by bearing the design force from the nut to the anchor plate.

Thus, the tack welds in question could not impair the functional capacity of the bolt assembly.

e It has been noted that ASTM h k h C.

d ASTM A-540 and ASTM A-320 bolts utilizing a procedure that had not been qualified for welding these materials t: cach other.

It is further recognized that this activity was in violation of AWS-Dl.1 code requirements.

However, upon discovery of the non-confor=ance, the pro-cedure that had been utilized was qualified in accordance with AWS requirement 3.

It is the engineers position that although the sequence of qualification and production i

welding was not as prescribed by the code, the post quali-fication has confirmed that the welding procedure utilized will produce acceptable welds.

The engineer is satisfied that the welds involved in the above described procedure will gerform their required design function and should be

.used as-is",

This position is further supported by the opinion of M.

Davis of the AWS as recorded in a telephone conversation with R. C. Barber of G&H on July 29, 1977.

j The procedure for welding ASTM A-540 to ASTM A-540 has been qualified (phone conversation R. C. Barber with M. Davis of AWS, August 3, 1977).

Both ASTM A-540 and ASTM A-320 y

are AISI 4340.

Therefore, the welding of A-320 bolts to 6

A-540 nuts is qualified.

COMANCHE PEAK STEAM ELECTRIC STATION 1980-82 2300 MW INSTALLATION SPECIFICATION 2323-SS-17 MISCELLANEOUS STEEL ANCHOR BOLT DETAILS REF. TUF-3286 FILE 05217 Regarding the referenced letter which inposed a hold on welding to anchor bolts, we are transmitting the attached sketch which shows an alternate mechanical connection.

g This detail was reviewed by the Design Engineer on Tuesday, July 12, 1977.

At that time, he confirmed that this configuration would satisfy the basic concern that the plate washer be held securely in place prior to and during concrete placement activi -

ties.

Based on the Design Engineer's comments, this change will have no detrimental effect on plant safety.

Therefore, in accordance with the G6H policy as of July 13, 1977, this change is autho-rized by the undersigned in advance of formal changes to the de-sign documents.

Construction may proceed subject to your approval.
