SUBJECT: MEETING SUMMARY - JULY 28, 1994 MANAGEMENT MEETING(TAC M72494)

REFERENCE: Meeting notice by P. S. Tam, July 19, 1994

On July 28, 1994, NRC and TVA representatives met at the Watts Bar site todiscuss the problems, concerns and needed actions associated with constructionand licensing of Watts Bar Nuclear Plant, Unit 1. Enclosure 1 is a list ofmeeting participants and observers. Enclosures 2 and 3 are TVA's handoutmaterials.

The staff stated that the ongoing action regarding assessment of the 1978Final Environmental Assessment (NUREG-0498) and Watts Bar's EnvironmentalImpact Statement would not be discussed in the meeting, but would be thesubject of a separate, future meeting.

The staff also stated that the issue concerning a recent NRC Inspector Generalreport (regarding allegers' identities), which received media interest, wouldnot be discussed in this meeting.

TVA's presentation followed the slides in Enclosure 2. The staff and TVA madethe following comments and commitments:

o Regarding Watts Bar milestones (shown on Pages 17 and 19 of Enclosure2), the staff expressed concern that closure packages prepared by TVAfor certain corrective action programs and special programscharacterized as "complete" or "75% complete" did not meet thecharacterization. The staff (Region II) will set up a meeting within amonth to discuss the results of TVA's assessment of closure status.

o Regarding lessons learned from the hot functional testing (HFT), TVAstated that within two weeks, it would be ready to discuss with thestaff, in a technical meeting, various problems encountered and followupactions. In particular, the staff would like to discuss theimplications of the lessons for future activities, such as the HFTretests, the performance of the operators and their readiness to operatethe plant safely.

o The staff will meet with TVA to discuss TVA's proposal to change severaltests under Preoperational Test Instructions (PTIs) to Acceptance TestInstructions (ATIs). TVA's proposal had been discussed with the staffin a technical meeting on July 6, 1994, and described in TVA submittalsdated July 14 and 20, 1994.

the nature of the changes, especially justification for any decreasedefforts from those previously approved in Watts Bar Safety EvaluationReport, Supplement 12.

o The staff will have discussions with TVA regarding updating the FSAR toinclude a description, by reference if appropriate, of the variousspecial and plant-specific processes (e.g., corrective action programs,special programs, reliefs to ASME codes) associated with Watts Barlicensing, but not specifically described in the FSAR.

o The staff stated that future management meetings should de-emphasizestatus summaries, and emphasize discussion of specific issues thatwarrant senior management attention.

Facts AteWWatts Bar Nuclear Power Plant

OwnerTennessee Valley Authority

CapacityTwo 1,270 megawatt units (2,540 million watts total)

Site1,700 acres including the hydro station and coal plant on the Tennessee River in SpringCity, Tennessee.

FuelSlightly enriched uranium dioxide pellets in fuel rods clad with Zircaloy metal. 264 fuel rodsper fuel assembly, 193 fuel assemblies per reactor.

Reactor InformationWestinghouse pressurized water reactors fabricated of carbon steel with an internalstainless steel cladding.

Inside diameter - 14.4 feet (4.39 meters)Inside height - 43.8 feet (13.35 meters)Side thickness - 9.4 inches (23.86 centimeters)

Holds fuel assemblies. This is where heat is produced through the fission process.

Nuclear ProcessWater in the reactor is heated by uranium fuel being split or fissioned. Heat is releasedfrom the fission process. The heat is used to make the water in the reactor vessel very hot.This heated water then goes to the steam generator. The steam generators use the heatedwater to boil a secondary source of water, creating steam. The steam is used to turnturbines which spin a generator producing electricity.

Steam Generator4 per reactorHeight - 67.6 feet (20.60 meters)

Heated water from the reactor passes through tubes inside the steam generatorswhere heat is given up to a secondary source of water. This secondary watersource boils and turns to steam. A

E- - - - m - m uIurbines W1 high pressure3 low pressureTurbines rotate at 1,800 rpm (revolutions per minute)Steam inlet temperature to high pressure turbine: 541.50 F (2830 C).Steam inlet temperature to low pressure turbine: 5140 F (267.80 C).

GeneratorProduces 24,000 volts. Power leaves the generator and is directed to transformers in theswitchyard where it is stepped up to 500,000 volts.

CondenserA large box with hollow tubes running through it.

Steam from the steam generator passes through the condenser to be turned back intowater.

Water from the Tennessee River passes inside the tubes in the condenser as the steampasses around the outside of the tubes. The steam, as it is cooled, turns back into water.The water in the tubes picks up the heat from the steam. This heated water then goes tothe cooling towers to be cooled. The cooled steam, or water, is sent back to the steamgenerators to be boiled again.

Cooling TowersTwo cooling towers; one per unit.

Height - 504 feet tall (153.62 meters)Width at base - 405 feet (123.4 meters)Each tower basin holds 4,800,000 gallons of water (18,168,000 liters).The water in the condenser tubes that cooled the steam goes to the cooling towers.410,000 gallons per minute (1,551,850 liters) of water passes through the condenser andthen to the cooling towers. The towers remove heat from the water. What goes out thetop of the tower is evaporated water and warm air. The cooled water which falls to thebottom of the tower is collected in the basin and pumped back into the condenser. This isa closed loop system with no water being directed back to the river.
