March 22, 1982 DISTRIBUTION TRIP REPORT - VISIT TO NRC-NRR AND TO CALVERT CLIFFS PWR POWER PLANT, WORK ORDER 20-81-165 - RGB-3-82 On Monday, February 7,1982, C. Toole and I met with Mr. Warren Minners and Mr. Ron Emrit of NRC-NRR at the Phillips Building in Bethesda, MD to discuss generic problems which possibly could be tasks for EG&G Idaho

?

to solve. Mr. Minners gave us a list of problems which had been categorized by priorities. Thirteen high priority problems were identified.

Ron Emrit supplied task descriptions and supporting documents for six of the tasks, and promised to send additional information on the remaining ones. Minners asked that EG&G prepare draft statements of work to 1) study the problems and prepare feasible alternate solutions, 2) prepare cost estimates for alternates with recommendations for most reasonable solutions and 3) prepare and submit a summary letter report to NRC-NRR.

C. Toole and I committed to submitting a set of draft Statements of Work by the end of February.

On February 8, 9 and 10, I met with personnel of Baltimore Gas and Electric

-(BGE). Tuesday, February 8, I obtained drawings and a procurement speci-fication for a feedwater isolation valve. Wednesday, February 9, I met with instruments and controls personnel to obtain cost data on control room modifications. Thursday, February 10, I visited the Calvert Cliffs plant and obtained cost and scheduling data from plant personnel.

The results of my discussions with BGE personnel are summarized below:

1.

The two main feedwater control valves are located in the turbine building which is not designed to withstand a Category I earthquake.

2.

Main steam and feedwater isolation valves are located outside containment in the auxiliary building which is built to withstand a Category I earthquake.

I received drawings showing dimensions, lengths and elevations of piping and the locations of feedwater isolation valves.

BGE personnel agreed to take photographs and send to me which show potential installation location for an additional feedwater isolation valve in each of the two feedwater lines to the steam generators.

3.

I received a cost breakdown (attached) for the cost to install an additional isolation valve in the feedwater line. The cost estimate was based on recent BGE experience in modifying the auxiliary feedwater system.

4.

I inquired if the existing feedwater isolation status and control station on the control room panel could be utilized to status and control two isolation valves instead of one, and I was informed that the existing panel hardware and logic would not handle the additional current load.

5.

I was shown the existing control room panel where the additional feedwater isolation valve control stations would have to be installed.

The panel is already overcrowded and the whole panel would have to be redesigned and reworked to handle two additional feedwater isolation valve stations. A sir..ilar problem existed when the auxiliary feedwater systems were recently modified --

two control room panels had to be rebuilt at a labor cost of over 4,000 hours0 days <br />0 hours <br />0 weeks <br />0 months <br />.

6.

I discussed scheduled outages and durations for both PWRs with BGE personnel. The currently planned outages for refueling, etc. are as follows:

Unit 1 1985 - 1 outage (14 weeks) 1987 - 1 outage (14 weeks)

Unit 2 1984 - 1 outage (44 weeks) 1985 - 1 outage (14 weeks)

The revenue loss per day for an outage of one of the units varios with the season and ranges from $750,000 to $1,200,000 per day.

BGE personnel stated that they felt that installation of two new feedwater isolation valves would add 3-4 days to a scheduled 14-week fuel reload outage.

l 7.

All valves, pumps, etc. in the auxiliary buildings have extensive maintenance work scheduled as part of each planned outage. There are moderate (?) reactivity levels in the auxiliary building and all work will have to be done in protective clothing and under health physics control. Multiplying the estimated labor for a job by an interference factor of 2.5 is normally used by BGE to take into account work interferences and work performed with protective clothing.

Mr. K, Nietmann, BGE, agreed to obtain additional costing (details 8.

and supply them later via phone. He subsequently did so see attached telecon).

t l

Distribution March 22,1982 RGB-3-82 Page 3.

During the meetings, I was given two drawings of the feedwater system and a feedwater isolation valve specification.

I will retain the drawings and valve specification in my files. The BGE personnel were very helpful and candid during discussions.

I consider that the trip was worthwhile.
