Dear Mr. Denton:

i This letter'esponds to Mr. J, G. Keppler's letter of August 2, 1982 which confirmed that as a result of a management meeting conducted at the PRC Region IEI office on July 7, 1982, AEP had agreed to provide the foJlowing information:

a. Formal conceptual design description of the Emergency Operations Facility (EOF) by August 1982,

b. Revision to the site Emergency Plan by August 13, 1982, and,

c. Additional information relating to the permanent TSC.

A formal conceptual design description of the EOF was submitted in our letter AEP:NRC:0531D dated August 27, 1982. The revision to the Donald C. Cook Nuclear Plant Emergency Plan was submitted by our letter AEP:NRC:0719 dated August 12, 1982. This letter and its attachments provide the additional information relative to the permanent TSC.

Attachment 1 to this'letter is a description of the Technical Support Center for the Donald C. Cook Nuclear Plant. Attachment 2 to this letter contains a revised conceptual design description of the TSC Plant Safety Status Display (PSSD) previously submitted to you in AEP:NRC:0531A. You will note that there are a few minor chang:s to provide you with a more concise description of our PSSD System and eliminate a description of TSC and EOF functions which are des ribed in the documents listed above. Changes are so indicated in the r; ght hand margin.

Mr. H. R. Denton AEP:NRC:0531E The information provided in Attachment 1 to this letter represents-the Technical Support Center as we expect it to be by October 1, 1982.

Changes may be required to accommodate unforeseen equipment problems, delivery schedules or experience gained with emergency plan drills and exercises. Revision 1 to the Emergency Plan will be tested in the Technical Support Center during our next emergency exercise planned for Octobez 21, 1982.

We look upon these exercises as an opportunity to test our concept of emergency operations. We will modify our organizational concepts and emergency response facility design as necessary based on the experience

gained, We have been informed by our supplier (Westinghouse) that despite the fact that they are making every effort to meet the October 1, 1982 date, they do not expect to be able to provide us with an operational PSSD (Plant Safety Status Display) terminal for Unit 1 in the Emergency Operations Facility until approximately 14 months after the PSSD in the TSC is operational. This is due for the most part to difficulties encountered in getting the TSC PSSD final software started up and tested. A completely operational TSC PSSD 4s needed before the EOF PSSD requizements can be incorporated into the system. We are in the process of doing preoperational tests on various EOF information and display systems. We are proceeding to expeditiously solve those start up problems that we encounter in the testing process, Testing and correction of problems will extend beyond the October 1, 1982 date indicated in ouz letters No. AEP:NRC:0715, dated July 30, 1982, and No.

AEP:NRC:0531D, dated August 27, 1982.

ATTACHMENT 1 TO AEP:NRC:0531E DONALD C. COOK NUCLEAR PLANT TECHNXCAL SUPPORT CENTER (TSC)

Desi n of the TSC This is a description of the Technical Support Center (TSC) for the Donald C. Cook Nuclear Plant, A description of the Emergency Response Organization, how that organization would be mobilized to activate and staff the Technical Support Center, and how it would interact with other response facilities is provided in Revision 1 to the Donald C. Cook Nuclear Plant Emergency Plan, dated August 13, 1982 (Section 12.3.9.4),

submitted to the NRC by our letter AEP:NRC:0719 dated August 12, 1982.

The Donald C. Cook Nuclear Plant TSC is a two story structure located in the Turbine Building ad)scent to the two control rooms. This location readily allows for face-to-face interaction between the control room personnel and the senior plant management in the TSC. Because of the proximity of the TSC to the control room it will normally take less than 2 minutes to travel from one facility to the other. The lower level of the TSC (elev. 633' is comprised primarily of the Shift Supervisor's Office, the TSC Computer room and a file room. The upper level (elev.,643') houses the Plant Evaluation Team area which contains the computer consoles described in Attachment 2 herein, the dose assessment and commmunications area, and a separate office with sufficient working space for five (5) NRC representatives that can be used for private NRC personnel consultations. The staffing and utilization of the TSC has already been tested in dxills and exercises with the result that there is sufficient space for plant emergency personnel to perform their assigned functions. Figure 1 is a layout diagram of the TSC; please note that changes to the arrangements of displays and furniture may be made to facilitate our operations.

The TSC has been constxucted to provide the same degree of radiological habitability as the control room under accident conditions.

Concrete shielding has been provided to significantly reduce the effects of containment building shine during an accident. Radiation monitoring has been provided to indicate radiation dose rates as well as airborne radioactivity levels including radioiodines.

The Donald C. Cook Nuclear Plant TSC has been designed to.')

Provide plant management. and technical support to plant operations personnel during emergency conditions.

2) Relieve the reactor operators of peripheral duties and communications not directly related to reactor system manipulation.

3) Prevent congestion in the control room.

4) Perform EOF functions for an Emergency "Alert", and for a "Site" Emergency and a "General" Emergency until the EOF is functional.

The following communications systems have been provided in the TSC Plant Fire and Emergency Radio to communicate with the radiation monitoring teams as well as with any in-plant teams.

Dedicated line on the NRC Health Physic network and two dedicated lines on the NRC Emergency Notification System.

Plant intercom/PA system Dedicated communication circuit to the control room and Emergency Operations Facility, Facsimile transmission capability 2 Extensions off the Visitors Center phones for the purposes of news releases/public information to the news media 2 private lines off of D. C. Cook PBX dedicated for NRC use with outside capability.

Additional telephones to be used as needed.

In general, the TSC will be operat'onal by October 1, 1982.

However, due to delays in delivery, the Heating, Ventilation and Air Conditioning system for the private NRC office, may not be operational at that tMe. Other problems do exist with the processing of signals and with the final operability of the display terminals. Ne are proceeding to remedy the problems we are encountering as expeditiously as possible, As of now, however, we do not have a date by which all problems will be resolved.

The data display terminals in the TSC will provide the capabilities described in Attachment herein.2 A description of these data display terminals in the EOF is provided in AEP:NRC:0531D dated August 27, 1982.

The schedule for the installation and operation of the different display terminals is:

1. MIDAS TERMINAL To access and fully utilize the MIDAS (Meteorological Information and Data Acquisition System) system a Tektronix Graphics Display Terminal and Hard Copy Unit will be available in the TSC. The.

equipment is scheduled to be installed by October 30, 1982. This equipment is being shipped to the Plant from the AEPSC offices in New York.

2. CPM002 TERMINAL CPM002 is accessed through 4:he Time Sharing Option (TSO). An IBM CRT is currently available in the TSC.

3. RADIATION DATA DISPLAY SYSTEM Delivery of color graphic CRTs for the TSC and EOF are expected in October. The CRTs will be connected to the Plant Radiation Monitoring System control terminals via modems and redundant communication channels, PLANT SAFETY STATUS DISPLAY (PSSD)

The purchase order for the PSSD as well as other post-accident monitoring displays in the TSC was placed with Westinghouse on May 22, 1980. It is our belief that due to difficulties our supplier (Vestinghouse) is experiencing in developing the software for the TSC computer, we will not have an operational PSSD by the expected date of October 1, 1982.

In the event that aU. the terminals described above are not operational by October 1, 1982 we will perform the functions as we have in the past (that is, by telephone communications and use of parameter data forms) . The adequacy of this mode of operation was demonstrated during our last full-scale emergency exercise of March 30, 1982.

The TSC will not contain, but will have ready access to plant records, drawings and other documentation as required. In addition the TSC will be in communication with technical support personnel in the Engineering EOF (located in the AEPSC offices in New York) during the initial phase of the event. until the EOF in Benton Township is activated. Revision 1 to the Emergency Plan provides a more detailed description of our concept of operation of our Emergency Response Facilities,
