Subject:

Revised Responses to RAIs 430.67 and 430.69; (Power Systems Branch)

Dear Sir:

In FSAR Section 7.4.2 (as revised in Amendment 49), we eliminated two areas f rom those that we consider necessary to be manned during Remote Safe Shutdown. The two locations are RHR Vault A and RHR Vault B.

As a result of the elimination of the two locations, emergency lighting and communications for these areas are no longer necessary.

Enclosed are annotated responses to RAIs 430.67 and 430.69, which reflect these emergency lighting and communication changes.

These will be included in a future OL Application Amendment.

Very truly yours, YANKEE ATOMIC ELECTRIC COMPANY 8312140100 831205

('t The information regarding the On-Site Communication System 430.67 (9 5.2)

(Section 9 5.2) does not adequately cover the system capabilities during transients and accidents. Provide the following infonnation:

(a) Identify all working stations on the plant site where it may be necessary for plant personnel to communicate with the Control Room or the emergency shutdown panel during and/or following transients and/or accidents (including fires) in order to mitigate the consequences of the event and to attain a safe cold plant shutdown.

(b) Indicate the maximum sound levels that could exist at each of the above identified working stations for all transients and accident conditions.

(c) Indicate the types of Communication Systems available at each of the above identified working stations.

p?- Tabulation of Communication Equipment, identifies by building elevation the communications available throughout the nuclear island buildings. This extensive f

communication network assures that communications are in close proximity to other areas where it may be desirable to monitor, operate or maintain equipment. Additionally, the radio system with the repeater and radiax (Note 1) is designed to provide communication between all areas of the station (except the Containment Building) via hand-held portable radios. Even without the radiax the hand-held portable radios will assure that communications are available at the locations that are required to be manned to bring the station to hot and cold shutdown for all design basis events.

(e) The telephone is designed to provide satisfactory performance under the following conditions:

Up to 60 dba - Standard Handset Up to 70 dba - Volume Control Handset Over 70 dba - Sound Absorbent Booths The paging stations are designed to provide satisfactory performance under the following conditions:

{

r.-

- a Up to 100 dba - Standard Handset Over 100 dba - Sound Absorbent Booths Headphones will be provided as necessary to assure effective communication via the sound powered system.

Mobility and individual volume control on hand-held portable radios assure that this system will provide ef fective communications under the maximum expected noise levels.

Functional tests will be conducted under conditions that simulate the maximum plant noise levels being generated during the various operating conditions and accident conditions to demonstrate system capabilities.

(f) The telephone system PABX is located in the construction office building and is powered by an off-site construction power source. Following completion of Unit 2, power will be supplied from a Unit 2 non-safety power system. Back-up power to the telephone system PABX is provided by a dedicated engine generator unit that supplies power to the telephone system and its HVAC System only.

The Public Address (PA) System for Unit 1 is powered from a Unit 1 Train "A" UPS bus. The' PA System for Unit 2 is powered from a Unit 2. Train "A" UPS bus.

(-s)

The hand-held portable radios are powered by rechargeable batteries. The repeaters for the station radio system are powered from a non-safety power system.

Back-up power is provided by dedicated batteries rated for 8-hour use.

F v,

The sound powered telephone system requires no external power supply to maintain its function.

7 (g) The following protective measures have been taken to assure a functional 3y operabic oa-site Communication rystem:

I The power supplies for the various communication systems are diverse (see Response (f)).

The Communication Systems are physically separated. The telephone PABX is located in the construction office building. The paging control cabinet for Unit 1 is located in the Unit 1 Turbine Building Relay Room. The paging control cabinet for Unit 2 is located in the Unit 2 Turbine Building Relay Room. The radio system repeater stations are located on Elevation 50'-0" of Unit 1 and Unit 2 Turbine Buildings.

Cables for the PA System are run in Train A raceways that are differest from those used for the telephone system.

The jacks for the dedicated sound-powered loop which provide communications between the remote shutdown

~

'1dcations"are mounted in deismically' qualified equipment or are mounted in individual junction boxes which are

}

seismically supported. Many of the jacks on the other sound-powered loops are also mounted in equipment which is seis'mically qualified. The switching panel for the sound-powered Communication System is located in the Cor. trol Room and is seismically supported.
