3 P00R BRIGINAL Roger S. Boyd, Assistant Director, Raactor Projects Divisica of Reactor Licensing Original Signed by THRU: Charles G. Long, Raaetor Projeit Bmch 3 Charles G. Lorg Division of Reactor Licensing TRIP TO THREE MILE ISLAND NUCLEAR STATION (DOCKET $0-289)
This writer (D. F. Ross) and D. E. Whitasell (CO:I) visited the Three Mile Island nuclear site on May 16, 1969. The trip was primarily for orientation and observation of the construction. Personnel contacted included:
George Bierman, Mat-Ed Gene Brecauch, UE&C QC George Dorn, UE&C Project Supt.
Some blasting had just been completed to enable insem11stion of a bypass line in the cooling tower recirculation' system. Mat-Ed hopes to get permission from the State of Pennsylvania to use the cooling tower bypass, i.e. use river wetar for condensing, in winter periods of high-fog.
(This option was not discussed in our CP review, and neither we nor F&WL have considered this in our evaluation.)
We visited a portable shop, owned by Mat-Ed but operated by Pittsburgh Testing Laboratory, for concrete and steel tasting. Many concrete speci-mens were in the curing room. Rabar and Cadwald splices had been tasted in the puller.
Tendon ducts were on sita, in a permanent warehouse, Some were galvanized sheet metal; others (curved sections) were thicker tubes.
Se=4nta=s-steel welding was being done in another permanent warehouse.
Drain lines for the reactor building were being assembled. Also, train-ing on primary system welding technique was in process. This building was nest, orderly, and well-lit.
The containment liner was up to the spring-lina. The outer concrete rstaining wall was in. The lower secttons of the vertical tendon ducts vers installed. The base mat was being finished. Concrete pour for the cylinder walls was scheduled to start the week of May 19. Welding was being performed in the reactor building sump area, on the 14-inch samp lines as they attach to the sump wall.

2-MY 2 31963 Kogar S. Boyd The auxiliary building foundation:. was in place, and three reactor coolant bleed tanks were in place.
The turbina pedestal concrete was essentia.11y complete. Staal framework for the turbine building was going up.
The two croling towers ware started, with concrete pour now 40 feet above grade.
Nota: The construction drawing for the reactor building sump lines to the ECCS system calls for 14-inch lines. In the PSAR the following information is found a.
Volume 4, Suppiament 1, Q 5.7 Says suction lines are two 12-inch diameter.
b.
Volume 1, Chapter 5, Table 5-3 (page 5-20)
Penetration Numbers 352, 353 show a line size of 14-inch diametar.
c.
Volume 1, Chapter G. Figure 6-1 Nota en drawing says RB sump suction lines changed front 14 inches to 18 inches.
Presumably the final design calenistions showed why 14 inches, instead of 12 inches or 18 inches, was selected. We should request Compliance to make a routina inspection of the A/E, Gilbert Associates, focussing on the procedures for implamenting FSAR commitments in the final design.
