Areas Inspected: Routine, announced inspection of mechanical equipment, piping, ana electrical systems installation; construction progress; and schedule statu :39(1':, 19(H)3(i :39(>510 PDR ADOO,: OS0(H)602 0 F'DC

Results: Within the areas inspected, no violations or deviations were identified. Finish work and punch list item correction are in progress. Core structure installation is essentially complete with beam tube alignments in progress. Some schedule slippage has been identified. After review and discussions of the water intrusion found in the beam tube, 1t was concluded that there was no further concern for the pool liner (see paragraph 3 for details).

- Denotes attendance at exit interview. Construction Progress The NRC inspectors toured the facility to view work in progress, review completion status, and observe general conditions. Finish work and correction of punch 11st items were in progress. Major construction items are complete. NETL personnel have accepted the reactor room and control room for occupancy. This will allow General Atomics (GA) personnel to proceed with mechanical and electrical installations prior to f1nal facility acceptance by the Universit During the tour, it was noted that the pool water cooling system was complete except for the installation of the supply and return tailpieces into the pool. The problems w1th the cleanliness of the heat exchanger and the epoxy chipping on the large size valves were resolved. The heat exchanger was cleaned by the manufacturer's representatives. The large size valves were returned to the supplier after the NETL personnel advised them that proper protection in shipping should solve the proble Replacement valves were received in good conditio The skid mounted pool water purification system was installed, and the supply and return line installation was in final stages of completio The GA representative was in the process of completing the core support structure installation. Work in progress and ob5erved by the NRC inspectors was the beam tube alignmen A second GA representative is expected to arrive the week of Moy l. This individual will install the control room consoles and other electrical and electronic equipmen Physical security elements have not all been received. Installation has not started pending satisfactory completion of door replacement, window lock repairs, and other deficiencie Items remaining to be received from GA are the Argon 41 rad1ation monitoring system and the detector chambers. The detector chambers are scheduled for shipment after licensing, as scheduled.
3. Water Intrusion Into Beam Tube NETL personnel discussed with the NRC inspectors their concern when water was found in the beam tube. Apparently. the only source was from a gap between the pool aluminum liner and the concrete biological shield. It was theor1zed by the licensee that the gap was generated by concrete shrinkage during the curing. The water could have come from the wetting down required during the concrete curing process and/or from the recent reactor room cleaning and washdown. The pool lip seal was installed after these events. The liner has a multinle coat sealing system on the outer surface to prevent corrosion, consisting of a primer paint, epoxy coating, and a bituminous sealing materia During the inspection, the water seep;:.ge had stopped or reduced to a rate that was less than the rate of evaporation. Subsequent to the inspection, the NRC inspector discussed the water sPepage matter with the NRR program manager for the facility. The consensus was that, with the liner coating system and permanent lip seal installation. there should be no further water intrusion or aluminum corrosion concerns.
4. Schedule Milestones The milestone schedule/completion dates, as published in NRC Inspection Report 50-602/89-01 1 have been revised and are as follows, as of April 28, 1989:
