- 4. DEFINITION 4.1 Technical Support Center (TSC) - An area onsite in close proximity to the Control Room which has the capability to display and transmit plant status information to the individuals who are knowledgeable of and responsible for engineering and management support of reactor operations in the event of an emergency situation.
- 5. ACTIONS 2 5.1 The Technical Support Center is located at the Davis-Besse site, along Ohio State Route #2, in the Davis-Besse Administration Building. The primary function of the TSC
- is to house and support an organization that provides management and technical assistance to the Station opera-tions personnel during emergency conditions and to prevent i .
or mitigate the consequences of abnormal plant conditions. l The TSC provides direct voice and data communication with the Control Room and serves as a primary communications I . e w - -- + + <- e y e t , , . .w w 9 y c.- mr. ,

\ 5.4.6 The Station Operations Manager may establish the
\ following telephone communications loops as needed per the DBNPS Emergency Plan Telephone Dir-ectory:
- a. Technical Data Loop 1.
- b. Technical Management Loop
- c. Policy Management Loop .
- d. Public Relations Loop NOTE: If personnel are required as communicators, requests should be directed to the Operations Support Center.
5.4.7 The Station Operations Manager should assign an indi-vidual(s) to distribute applicable emergency equipment 3 listed in Attachment 1, (ie. log book, telephone books, and calculators). 5.4.8 Upon arrival, the Onsite Assessment Manager will assume control of the TSC from the Station Operations Manager. l 5.5 Onsite Assessment Manager 5.5.1 The primary Onsite Assessment Manager is the Nuclear Engineering Manger. I i 5.5.2 The alternate Onsite Assessment Manager is the Plant Nuclear Systems Engineer. 5.5.3 The Onsite Assessment Manager, upon being informed that an Alert level emergency exist, shall proceed to the Technical Support Center (TSC). I 5.5.4 The Onsite Assessment Manager's responsibilities and duties include, but are NOT limited to:
- a. Directing the engineering assessment activities of the TSC.
- b. Coordinating the engineering assessment activities of engineering support personnel from the NSSS vendor and the Architect Engineer.
- c. Ensuring that adequate mechanical, electrical, k instrumentation and control, and technical W * * ~ * * ' - - ,

\ 5.7.2 The alternate Radeon Operations Manager is the s'( Chemical and Radiation Protection Engineer.
5.7.3 The Radeon Operations Manager directs and coordinates the radioactive waste and radio-logical controls aspects of Emergency Operations
. and keeps the Plant Operations Manager informed of radwaste and radcon activities pursuant to
. the emergency.
5.7.4 The Radeon Operations Manager is responsible for coordinating the activities of the Health Physics Monitoring Room portion of the Opera-tions Support Center, however he may do this from his office located in the Technical Support Center. He is also responsible for relaying health physics information over the NRC Health Physics Network phone which
- is located there.
5.7.5 The Radeon Operations Manager shall supervise the onsite radiation surveys and survey results analysis.
< 5.8 Plant Staff 2 5.8.1 Plant Staff, such as the operations engineering staff, clerical support, etc., who are NOT assigned to other emergency functions, shall (if in protected area) report to the Operations Support Center and be directed to the TSC as , needed.
- 5.8.2 The Technical Engineering staff who are not l assigned other emergency functions, shall report directly to the TSC.
l , 5.8.3 The Plant Staff shall assist in accident assess-l ment, as required. t 5.9 Technical Support Center Activity 5.9.1 Communications with the Control Room, Emergency Support Center, Operations Support Center, Emerg-
. ency Control Center, and the NRC will be estab-lished as specified by the Onsite Assessment l
Manager or the Station Operations Manager.

\ 5.9.6 A record of activities of the TSC shall be
( maintained to the best ability of personnel present. Record disposition shall be in accordance with EI 1300.12, Administrative Controls. 5.9.7 The decision to deactivate the TSC shall be made by joint concurrence of the Onsite Assessment Manager, Station Operations Manager, Shift Super-visor and other key plant personnel once accident recovery has reached a point where continuous technical assessment and advisory functions are no longer necessary to mitigate the consequences of plant conditions. 5.10 Procedure for Activation of the Alternate TSC 5.10.1 The Onsite Assessment Manager will direct the activation of an alternate TSC if the normal TSC becomes uninhabitable for any reason. 5.10.2 No more than three (3) persons assigned to technical support will be dispatched to the Control Room. The balance of the technical
< support staff (including vendor, TED and NRC personnel) will be located at a suitable posi-tion as close to the Control Room as possible.
Communications will be established by telephone, messenger, telecopier, etc. between technical support personnel and the Control Room. Also, communications will be established at least by telephone or messenger between the relocated TSC and the ECC. l l . I k h
