June 26, 1984 l Mr. H. R. Denton, Director Office of Nuclear Reactor Regulation U. S. NUCLEAR REGULATORY COMMISSION Washington, D. C. 20555 Attention: Mr. J. R. Miller, Chief Operating Reactors Branch 3 Gentlemen:

DOCKET NOS. 50-266 AND 50-301 IMPLEMENTATION OF POST-TMI RELATED ISSUES POINT BEACH NUCLEAR PLANT, UNITS 1 AND 2 Our letter, dated March 5, 1984, discussed several equipment receipt and installation delays for the. Auxiliary Safety Instrumentation Panels (ASIPs) and the instrument bus up-

. grade which impact the schedular commitments in the NRC's " Order Confirming License Commitments on Post-TMI Related Issues" dated July 12, 1983. Since our March 5, letter, we have experienced additional delays in the final fabrication and delivery of the ASIPs.

We have therefore worked with our panel supplier to deliver the panels separately in the sequence which best enables installation I to proceed, since physical restrictions in access to the control room require the panels to be moved and installed serially, with Unit 2 first and Unit 1 to follow.

Delivery of the Unit 2 ASIP, which includes the control and switching circuitry for the instrument bus upgrade, has been delayed although the panel underwent final testing in mid-April 1984. The panel failed portions of the annunciator tests and required.some minor electrical rework. This delay was lengthened due to problems in the construction of the steel floor penetration

~ sleeves which are required to be installed before (and below) the

'ASIPs.. The panel manufacturer has now completed the Unit 2 ASIP, has resolved the steel manufacturer's problems, and has stated that the floor penetration sleeves and the. panel will be shipped during the week of June 25, 1984.

In April 1984, the Unit 1 ASIP was in its final steel fabrication phase. However, several panel welds failed the Wis-consin Electric QA inspection. Additionally, some structural members required for CRT support, as well as access to certain

terminal strips, werd not included or were improperly placed.

Following' correctio,n of these deficicipier., the pancl was later rejected by the panel' supplier, enis time due to painting inade-quacies by a sub-supplier. The panel is now undergoing painting rework. The electrical compone'nt installation is scheduled to

'begin during the last week of June. The installation and final testing are expected t o take app.roximately 6sweeks. Delivery should take place in mid to late August.J984 Even with these delay.5, we expect to complete the startup and testing of' the instrumer.ts by October 31, 1984 for both units.

Achievement of the final power supply configuration is based on the timely completion'of the, bus upgrade venti]ation and air conditioning system. As we committed in our March 30, 1984 letter,

" Upgraded Emergency OperaKing Procedures)" we will attempt to have the instruments integrated _into procedures and operator training on the procedures completed by January 31, 1985.

Completion of the instrument bus upgrade and the associated battery and equipment rooms is dependent on'the operability of the ASIPs. As stated in our March 5, 1984 letter, the delivery of our air handling units for the ventilation and air conditioning (VAC) system for the new battery and equipment rooms was delayed until early June 1984 with the VAC system expected to be operational in September 1984. The expected operational,date of the VAC system may be affected due to problems procuring _ valves which meet our specifications and schedule requirements. We are attempting to resolve these problems and meet'the current completion schedule.

We will continue to keep you informed as to the status of these items. However, if you have any questions concerning this information, please don't hesitate to contact us.

Very truly yours,
