Beaver Valley Power Station, Unit No. 1 Docket No. 50-334 NUREG 0578 Item 2.2.2.b, Technical Support Center

Dear Mr. Denton:

On March 7, 1980, members of my staff made a presentation before members of your staff on the conceptual design of the Technical Support Center planned for use in support of Beaver Valley Power Station. We have fully considered the comments of your staff given at that meeting and the subsequent Staff Position on Emergency Response Facilities issued by the Division of Operating Reactors on April 25, 1980, and have compared these requirements with our plans for the Beaver Valley Technical Support Center (TSC). We believe that our planned TSC meets the intent of NRC requirements in every important area thus far identified. We must take exception to the staff requirements in certain areas due to unique features of our facility and its site, but we believe that in these areas we have added compensatory features which fully meet the intent of the requirements.

We have thoroughly investigated a variety of locations for the TSC. This investigation has resulted in our selection of the recommended site for several compelling reasons. We have determined that it is impractical, because of structural considerations, to add shielding to existing facilities to meet shielding requirements for the TSC. Further, suitable sites for construction of a new building of the proper size immediately adjacent to the control room, or within the existing security boundary are totally impractical. Among the sites further from the control room, the recommended site h u the best combina-tion of desirable features.

We have also considered the establishment of primary and secondary TSC facilities in order to meet the letter of the requirements for this facility, and in our unique case, believe such a solution to be unsatisfactory. Any emergency that increased radiation levels onsite would likely require the evacuation of the primary TSC with resultant lost time and unnecessary con-fusion. Further, arriving offsite personnel would be uninformed of any change in TSC location, thus adding confusion, extending response time, and possibly increasing radiation exposure. Further, the transfer of personnel between centers would be mandated just at the time when their technical assistance would be most needed by operating and emergency personnel, .

B :v:r Vellcy Pow:r Station, Unit No. 1 Docket No. 50-334 NUREG 0578 ltem 2.2.2.b, Technical Support Center Page 2 Our concept of proper Emergency Response Facilities (ERF) is to establish at one location all of the facilities required to assure coordinated manage-ment of the total emergency situation, both in-plant and offsite. This planned ERF will be sufficiently protected from postulated env1ronmental conditions resulting from an accident so as to make ERF evacuation a remote possibility.

Our planned ERF will combine the TSC, the Emergency Control Center and the Near-Site Operations Center, all activities which should be coordinated by a single Emergency Director. This coordinated approach to emergency response is enhanced by providing good communications facilities, data acquisition and data display and sufficient working space to assemble the proper expert personnel representing equipment suppliers, the architect-engineer, emergency management agencies and other qualified personnel. This arrangement allows the Emergency Director and NRC, federal and state agencies to be immediately aware of any change in plant condition which has the potential for offsite consequences. Data acquisition and communication facilities will be immediately available at the TSC to permit monitoring of the offsite environmental con-ditions and to control offsite emergency teams. Close communications between the control room and the TSC will be provided by installing direct telephone communications and a " picture phone" type communications link. This will allow personalized contact between TSC personnel and NRC, NSSS and licensee personnel in the control room. In addition to allowing personal observation of control room activities by key NRC and licensee personnel, these communications links will provide a sense of " management presence" within the control room without causing unnecessary distraction to operations personnel. The plant security boundary will be extended to the TSC by using security vehicles to shuttle from the TSC to the control room, thus allowing authorized personnel rapid access to the control room after having initially met security requirements at the TSC.

We are convinced that our proposed Emergency Response Facility represent.

the most practical and logistically appropriate approach for our particular site.

Forwarded herewith are three (3) signed originals and 37 copies of a sum-mary review.description of the planned Beaver Valley Technical Support Center for your Because of the stringent schedule placed upon us to have an operable TSC by Janaury 1, 1981, we have and will continue to vigorously pursue the design and construction of this facility. Ground boring and subsurface soil analysis of the proposed location is now complete and the facility structural design has reached the stage where the start of construction is imminent. Even with this aggressive schedule, we do not expect to complete basic construction of the facility until January 1, 1982. Because of this timing, we will install sufficient closed circuit TV equipment of high resolution in the interim TSC to provide remote indication of approximately 85% of the control room instrumentation and virtually all instrumentation important to the control of accident conditions.
