Beaver Valley Power Station, Unit No. 1 Docket No. 50-334, License No. DPR-66 Control Room Wall Removal Gentlemen:

This letter provides a

description of our plans to remove the temporary wall separating the Unit 1 and Unit 2 Control room areas.

The temporary wall was installed between the two control room areas in order to operate Unit 1 prior to Unit 2's completion.

The wall served as an interim pressure boundary as well as a fire and security barrier.

As a result of the temporary wall removal, the capacity of the Unit 1 Control Room Emergency Ventilation System (CREVS) must be increased.

The current design of the Unit 1 CREVS only provides for pressurization of the Unit 1 control room envelope (CRE).

During the period when the Unit 1 CREVS is out of service for the necessary modifications, control room habitability will be ensured by maintaining the Unit 2 CREVS operable.

The Unit 2 CREVS is sized to service both Unit 1

and Unit 2

control room areas.

A Technical Specification Amendment will be proposed to allow continued operation of Unit 1 while the Unit 1 Control Room Emergency Ventilation Systems (CREVS) is out of service for equipment design modification.

The proposed Technical Specification Change consists of a note to be added to Specification 3.7.7.1.

Technical Specification Page 3/4 7-16 with the proposed note is presented, for information only, in Attachment 1.

A formal submittal of the proposed Technical Specification will be forwarded following onsite review and approval.

When Unit 1

CREVS modifications are complete and the system is verified operable, the temporary technical specification presented in Attachment 1 will expire.

At this time, we will request NRC approval of technical specification change request No. 126.

Technical specification change request No. 126 implements revised control room habitability specifications which reflect the Unit 1 CREVS equipment modifications.

Control Room Habitability Implementation Program (CHIP) has been developed to ensure operability of the Unit 2 equipment and support systems required to provide a safe and habitable environment in the combined control room while the Unit 1

CREVS is being modified.

The CHIP (provided as Attachment 2) includes a summary of planned

actions, Unit 2

equipment operability requirements, fire protection requirements and security measures.

Specific tasks involved with the removal of the temporary wall include the following.

Prior to removal of the wall separating the two control rooms and modification of the Unit 1 CREVS, a repairable test penetration will be made through the gypsum portion of the temporary wall.

Testing will then be performed to verify Unit 2 CREVS operability.

This testing will ensure that Unit 2 CREVS can perform the required functions necessary to maintain combined Unit 1-Unit 2

control room area habitability under postulated accident conditions.

It has been determined that the integrity of the Unit 1 control room pressure envelope will be degraded for a period of up to 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months when the test penetration is created in the temporary wall and subsequent Unit 2

CREVS operability testing is performed.

However, i

in the unlikely event that pressurization of the Unit 1 control room becomes necessary, the repairable penetration through the wall separating the two control rooms will be isolated.

After the Unit 2

CREVS is verified operable, removal of the temporary wall and modification of the Unit 1 CREVS may begin.

Temporary wall removal work is expected to begin as early as the last week of March, 1987.

If you have any questions regarding this matter, please contact Mr. Steve Sovick.

Very truly yours, A

SUMMARY

OF PLANNED ACTIONS A.

Diagrams and Description of Temporary Control Room Wall The temporary control room wall is located in the main control room area for Unit 1 and Unit 2.

Unit 1 control boards are on one side of the wall and Unit 2 control boards are on the other side as shown in Figure 1.

The wall is composed of 3/8" steel plate and several layers of gypsum board as shown in Figure 2.

The largest steel plate is 4'

x 10' and weighs approximately 612 pounds.

There are ten plates of this size and sixteen smaller plates.

Gypsum board thickness ranges from 5/8 inch to 2 inches.

Unit 1 systems expected to be out of service.

.The Unit 1 Control Room-Emergency Ventilation System will be removed from service to increase the fan size, increase the size of supply and discharge ducting for the fans and filter, and provide larger duct heaters and dampers.

It has been determined that the integrity of the Unit 1 control room pressure envelope will be degraded for a period of up to 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months when the test penetration is created in the temporary wall and subsequent Unit 2

CREVS operability testing is performed.

However, in the unlikely event that pressurization of the Unit 1 control room becomes necessary, the repairable penetration. through the wall separating the two control room will be isolated.

Therefore, specification i

3.0.3 will not be applied during this period of time.

Unit 1

Control Room Emergency Bottled Air Pressurization System (CREBAPS) will be modified by replacing the existing restricting orifices with larger restricting orifices to allow an increased flow rate of 200 cfm through each orifice.

(1,000 cfm total).

One orifice will be replaced at a time, thus allowing continued CREBAPS operability.

The average electrolyte temperature of every tenth cell of connected cells is above 60*F.

c.

At least once per 18 months by verifying that:

1.

The

cells, cell

plates, and battery racks show no visual indication of physical damage or abnormal deterioration, 2.

The cell-to-cell and terminal connections are clean, tight, and coated with anti-corrosion material, 3.
