SUMMARY
The. Reactor Bleed Tanks, field fabricated by. Pittsburgh Des Moines (PDM), are finished and set in place, and are awaiting the ASME code inspector to witness the hydrostatic test for acceptance.
The question concerning potential stresses induced by poor head fit-up remains outstanding.
An engineering evaluation by UE&C is scheduled The inspector,was informed by Met-Ed's site Quality Ass.rance Engineer, that forty (40) stainless steel floor drain castings had been rejected and returned to Zurn Manufacturing Company for re-placement.
Test coupons are being prepared in order to qualify the welding 9
procedures for the joining and cladding of the reactor coolant piping.

SCOPE An announced visit was made to the site of the Pressurized near Middletown, Water Reactor being erected on Three Mile Island, D. Ross, DRL, HQ, and Pa.
The inspector was accompanied by IW.
the purpose of the visit was to familiarize Mr. Ross with the site and the progress of the work.

PERSONS CONTACTED A.
Metrocolitan Edison Mr. George Bierman, Project Manager Mr. Vern Stuebner, Resident Engineer Mr. Gene Hraczuch, Resident GA Engineer Mr. Bud Avars, Quality Assurance Manager (GPU)

United Encineers and Constructors Mr. Gecrge Dorn, General Superintendent Mr. Milo Prisuta, Site CC Manager Mr. Karl Brooks, Welding Inspector III.
QUALITY' CONTROL ITEMS The inspector reviewed CB&I's Quality Control Plan for A.
the containment liner and found it to provide for the following essential items :
1.
Quality Assurance Policy 2.

NDT personnel to be qualified per SN-TC-1A if The inspector concluded that the procedures are adequate, implemented and properly followed.
This will be monitored on a future visit.
The inspector audited the Deficiency Reports developed by UE&C.
B.
These reports are presently filed by the defect subject.
Copies of the report are routed to GAI and Met-Ed for review and comment and for evaluation, and the final disposition is noted on the report, The inspector was informed by Mr. Hreczuch, Met-Ed that he C.
had rejected forty (40) stainless steel floor drains to be located in the containment Building.
Upon receipt of these castings from Zurn, Met-Ed requested a dye penetrant examina-tion to be made.
The penetrant ex.minations revealed linear 9
defects near the weld prep area which Met-Ed felt might prop-agate af ter the castings were welded into place.
Represent-atives from Zurn were called in and they agreed to replace these castings.
Mr. Hreczuch showed the inspector a condensate tank that had D.
been received from Youngstown Tank Company, which had a gouge in the head approximately 1/2" wide X 1 1/2" long X 1/8" to 3/16" deep. Since this tank operates under pressure and tem-Met-Ed has requested the manufacturer be brought
- perature, in to run an ultrasonic thickness check to make certain that the gouge does not encroach on the total required thickness of the head.
The results of this test will be reported on a future visit.

REACTOR BLEED TANKS Pittsburgh Des Moines has completed the fabrication of the A.
The three Reactor Bleed Tanks and has moved off the site.
Bleed Tanks have been set in their permanent location and are awaiting the arrival of the ASME code inspector to wit-9 ness their hydrostatic test for acceptance.
