Remote Tool Calibration JThe-(W) remote inspection tool is calibrated at the (W) plant in Watts Mill, Pennsylvania, using calibration biccks of the same material and heat treatment process as the. reactor vessel.

Prior to this examination'the licensee purchased.new calibration blocks . ' that were used -for this calibration.'. These -blocks are maintained

at (W) for the' licensee. Tool calibration for examinations scheduled

for-this outage were witnessed by the licensee and theLauthorized

inspector. The' calibration record; packages--listed below were L

licensee reviewed the radiographs of weld No.1 11 and 18.

No rejectable-indication's were.noted_.in the radiographs.

Some , acceptable. slag-and porosity.was present in the general area of -~ the weld root.- ~ ' ' s 'In order:to' evaluate.the questionable ~ reflectors, Westinghouse suggested using techniques previously~ utilized at other sites.

'During ultrasonic examination of the Ginna Station' reactor vessel, by Southwest.Research-Institute (SWRI) in March 1979, similar reflectors . were identified in the "B" inlet nozzle, and at Point Beach Unit 1,

. Lin February 1984,-(Licensee Event Report No. 84-02-00) similar reflections'were identified in the A and C outlet-nozzles of the reactor vessel.

, For!both: sites SWRI used a technique they developed in accordance _ with ASME Code Section XI, Paragraph IWA-2240 for measuring transducer ' beam sprea'd toJevaluate ultrasonic reflectors in vessels examined in accordance~with Regulatory Guide 1.150 by drilling a 3/8" flat bottom ~ . hole in the. calibration block at an; angle so that the-search unit produces a beam perpendicular to the flat bottom hole.at a metal path Jwithin 110 of the flaw indication metal path.

Using information contained in the SWRI report for the Ginna Station and at Point Beach, the Westinghouse' examiners determined the beam spread of the - ~ search units bei_ng used at Zion Station.

Fol' lowing instrument recalibratiion, weld No. '18
indication No._1, was freexamined without the' correction _ factors using the 10 longitudinal wave from the bore and the outside diameter.

Indication No. 2 was ' examined using 0 _ longitudinal __ wave from the: bore and outside. diameter.

.Both indications were mapped and sized in accordance with Regulatory

Guide 1.150, evaluated by the-Level III examiner and accepted in n

accordance with ASME. Code Section XI, Paragraph IWB 3512.1. Weld 'No._11, indication.No.;2 and 4,.were reexamined without the correction . factors'from the bore and outside diameter'using the 10* longitudinal ~ n
