Dick ras vivised t hat it appcated that Section 53.2.8.2 of the F"AR has L ca violated.

It was pointed out that this cection requicas 'that j

the r..unured elongatio ns of the tendons be check nd cgainst the c al-dated values and the cause of any discicpancy execoding plus or r

l

.inus five pc2 cent be corrected.

Contra ry to this re quir cnent, of the 105 tendous stressed as of May 28, 1970, 49 had exceeded the calculated l

value by as r.uch as 607..

(Subsequent to the inspection, the inspector was advised by telephone tLit of the next 30 stressed, only 6 had I

excceded the specified f he percent.) The inspector pointed out that the stressing oper tions ucre continuing even though the cause of the d isc repancy had r.ot been detenained and no specific corrective action had been t aken.

Dick stated that the licensee and Bechtel were studying the problem and that they expected to detetuine a course of action within th e next few days.

The possibility of modifying t he stiessing procedure to ensure that the slack had been taken out of the tendons prior to measuring the elongations was discussed.

Dick assured the inspectors i

that the cause would be determined and corrective action would be taken.

Dick stated that the drawings would be revioced and the ucazie diens'ous checked to ensure that the nezzles trould.atch beftre the valves were selded to the stcan line.

The inspcctor noted that the svallable naterial cert ificat ions for the niin steam piping had been revicued.

The inspector reviewed the records relating to the strecsing i

These cards, one for each tendon, ate preprinted with the tendon location utr.ber, the stressing force, and the calculated clongation.

of the jacks used and the date. Each card aust be signed by the QC inspector. The inspector pointed out to Wells and Hunnicutt that some of the' cards wre io m plete and that the Inspector had not sigand the cads in every case.

stated that these cards were for the fIrst few tendons stressed and heat number informatica and si oatuces had beca inadvertently C

In order to crpolice the st resses on the bu!1 ting, three tendons are st re ssed s imultaneo nly.

Since each done tendon is jacked f rca both ends, six crcus are required. The stressing is cont tolled by a coordirator who is in telephone contect with all six etcws.

The inspectors noted that the crews vere follcuing the establ1shed procedurcs.md that the QC Inspr ctor was observing t.f.e operations.

In a telecca on June 1, l970, the Region II innpectors na e info.

to ascertain that the critical crotch areas had been successfully j
