==
Description:==
The.!ollowing discussion describes the systems identified above.
The Technical Support Center Information System (TSCIS) provides data to the Technical Support Center staf f for their evaluntion.
The TSC consists of a Closed Circuit Television System (CC;V),
telephone communication equipment, access to control room recorders and-their associated'hard copy, and other. supporting equipment.
The objectives of the Technical' Support Center Information System are as follows:
A.
To provide information in the Technical Support center for analysis of the plant conditions and to alleviate the problem of control room overcrowding during an accident.
B.
To provide the basis for guidance to the control room operating personnel in the managemant of abnormal conditions and in accident mitigation.
C.
To provie'.e the basin for supporting the data needs of management personnel who will be located in the near-site Emergency Operations Facility (EOF) during recovery operations.
The design functions established for the Technical Support Center Information System (TSCIS) are as follows:
1 A.
The TSCIS shall provide to plant managemont and technical personnel the technical data which will enable them to:
7.
t Page 7 1.
Evaluate and diagnose plant conditio's.
- 2..
Provide guidance to control room personnel in management of accident conditions, accident mitigation, recovery from accident conditions, restoration of the plant into a safe condition, and resumption'of normal plant
- l-operation.
3.
Provide technical information to personnel in the Emergency Operation Facility (EOF).
B.
During the' recovery operation, the TSCIS shall aid the Technical Support Center (TSC) staff in their review of the accident sequence and the-determination of the status of operations.
C.
The TSCIS shall aid the TSC staff in their review of the plant-steady state operating conditions prior to an accident,-
the transient conditions producing-the initiating event, and the plant. systems' dynamic behavior throughout the course of the accident.
D.
The TSCIS shall also be capable of presenting the Safety Parameter Display System (SPDS) data in the TSC.
E.
Data provided in the EOF shall also be available in the TSC via the TSCIS.
F.
The TSCIS shall provide to TSC personnel the current value and time history of selected parameters available in the control room.
In order to meet these criteria a CCTV system will be installed, telephone communication will be established between the TSC, Control Room and EOF, and a procedure will be established to permit Technical Support Center personnel to have' access to hardcopy from control room recorders.
The dedicated j
communicators in the control room would be available to obtain the hard copies from the control room recorders.
The CCTV System will consist of four cameras installed in the control room.
The cameras will have remotely controlled pan / tilt and zoom. capabilities.
Each camera will be connected via video cable.to a dedicated TV monitor located in the TSC.
Individual wM-g
~
d Page 8 controls:will be provided in.the TSC for each camera to enable the cameras to be operated independently.
The camera controls will allow TSC personnel to manipulate the cameras for viewing of control room instrumentation on the TSC TV monitors.
This will provide'TSC personne1~with' current value information for selected
- plant data parameters.
The CCTV system will also provide TSC
- personnel.with an overall view of the control room and aid in communication with the. control room personnel.
A videotape recorder will be provided to permit recording of selected L
activities.
The CCTV System will be designed with an
-[
availability objective of 99%.
i TSC' personnel will utilize hardcopy from control room recorders to determine time history and trends of pre-event and post-event data.
The TSC Information System will also provide TSC personnel with meteorological and radiological data.
Monitors capable of continuously measuring the concentrations of
- airborne particulate radioactivity, radiciodine, and noble gases
- present in building air will be placed in the TSC and EOF.
Each monitor is capable of providing a local alarm when pre-set levels are exceeded.
Philadelphia Electric will, as part of a study to upgrade ti.e present process computer, investigate the possibility of adding a Safety Parameter Display System (SPDS) function to a new plant process computer.
If this approach proves feasible, a CRT-based SPDS display will be provided in the control room and the Technical Support Center.
III. Describe the TSC power supply systems, power supply quality, reliability and availability and consequences of power supply interruption.
I Svstem Description The TSC and the EOF will be normally fed from a 33 kV line l
with an onsite 1000kW, 480 volt diesel generator available for. emergency power as shown on the attached sketch.
The 33 kV line feeds a 2400 volt bus through a Westinghouse, 2000 kVA,'33 kV to 2400 volt transformer.
This 2400 volt bus L
feeds another 2400 volt bus through tie breakers.

The TSC and EOF electrical-power supply isfindependent'of the-Unit.2-3 power systems and therefore'will not degrade the capability or. reliability of any Peach Bottom Unit 2 or 3 safety-related power source..
4 Power Supoly - Offsite The_33 kV supply line originates at Susquehanna. Substation which is fed from Conowingo Hydro Generating Station.
The voltage and frequency on the 33 kV line are very stable under non fault conditions and are maintained within' limits that will not degrade the performance of any of the essential loads at-the Technical Support Center or the Emergency OperationsEFacility.
The 33 kV line has sufficient capacity i
available to' feed the Technical Support Center and the Emergency. Operations Facility.

Voltage is automatically controlled by a Westinghouse Transient Voltage Regulator and speed is automatically controlled by a Woodward Industrial governor.
Voltage and frequency are maintained within. limits that will not degrade the performance of any of the essential loads at the Technical Support Cen':er or the Emergency Operations Facility.
.The Diesel Generator has sufficient capacity to feed all the essential loads at the Technical Support Center and the Emergency Operations Facility.
Ouality and Reliability If the 33 kV line and the diesel generator are both lost, the Technical Support Center and the Emergency Operations Facility would be inoperative, however, the probability of total loss of power is very remote.
The total power system has an unavailability of 5.38 X 10;y The failure rate of the total power system is 2.59 X 10:= failures per year.
The reliability can be computed for any specific period of time
~X, where R is by using the following formula:
R(t)
=e reliability, x is the failure rate of 2.59 X 10:= failures per year, and t is time.

i PEACH BOTTOM ATOMIC POWER STATION ENCLOSURE 2 Technical Support Center & Emergency Operations Facility Request for. Exception to. Location Criteria Technical Support Center Philadelphia Electric Company's response to NUREG 0578 in our letter dated October 17, 1979, committed us to establishing an interim Technical Support Center-(TSC) by January 1,11980.
In response to'a' letter from H.
R.
Denton, NRC Director, to all Operating Nuclear Power Plants dated October 30, 1979, weitook action to meet the' implementation schedule mandated by that
' document. ' Specifically we were to establish an interim TSC by January 1, 19804.and a permanent TSC by January 1, 1981.
In order to meet these NRC commitments, Philadelphia Electric decided to use.the decommissioned Peach Bottom Unit I Administration Building for the TSC and EOF facilities.
The Unit I Administration' Building' is a three story structure located approximately 700 feet from Peach Bottom Units 2 and t
3.The onsite Technical Support Center (CSC) is located on the third-floor, which was the Unit I control Room and supporting facilities.
In order to meet the design criteria established in NUREG 0578,.that "the center shall be habitable' to the same degree as the~ control. room for postulated accident conditions";
additional shielding was added to the North Wall of the Control Room and the corridor.
We installed a dedicated HVAC system which utilizes HEPA and charcoal filtration and can be isolable from outsil air by dampers.
The total habJtable area dedicated to'the Technical Support Center is 4900 fr.
Thi: area includes a plant status display area, NRC office, PECO office, storage area, kitchen, lunch and conference area, records room, rest area and men and women's toilet facilities.
The Technical Support Center lies outside, but adjacent to, the main security boundary of Units 2 and 3.
A cyclone fence around the perimeter of Unit I and an entrance guard posted 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> per day affords security for the TSC.
NUREG 0696, Functional Criteria for Emergency Response Facilities, recommends a TSC location of 2 minutes walking time to the control room which exceeds the walking time at :4ach Bottom.1 We hereby request exception to this criteria for reacons discussed below.
1.
The close proximity of the TSC to the control room was recommended according to NUREG 0696 to facilitata face-to-face interaction between control room personnel and the' senior plant manager working in the TSC.-
The Peach Bottom-TSC will have dedicated telephone communications

~
=Page 2 i
4 with Lthe control ~ room, personnel dedicated to
- communications. assigned to the control room, and' a closed circuit TV system for monitoring plant' status.-
Additionally, the presence of'the Shift Technical Advisor in the control' room should enhance communications between the control room and. the technical staff located in.the TSC.
These provisions will provide satisfactory compensation for the planned location of the Peach Bottom TSC.
2.
Procedures will be developed to ensure that a motor vehicle will.be available for transporting personnel
-l
_between the'TSC building and the-Unit 2-3 structure.
This should reduce the transportation ' time between locatiens to approximately'3 minutes, including the time to walk from the motor vehicle to the control room.
3.
The location of the TSC is ideally situated by being l
~
readily' accessible from both Unit 2-3 and a public road.
The latter enhances TSC accessibility to offsite support _
i personnel such as (1) offsite engineering and management t
personnel, (2) vendors, architect engineers, and consultants, and (3) representatives from the Federal, State, and Local agencies.'
4.
The recommendation for face-to-face interaction contradicts the TSC function of preventing congestion in 1
the control room as stated in NUREG 0696.
Even if face-l to-face interaction capabilities are given a.high
,9 priority, it would be possible to address this concern i
by the mechanism of assigning a member of the plant's l
technical staff to the control room during the period that the TSC is activated.
J Emergency Ooerations Facility
^
The Emergency 0ferations Facility is located on the first and second floors of the Unit I Administration Building.
. published July 1980 states "mhe location of the EOF shall be i
balanced between close prc nuity to the plant to facilitate i
}
emergency response and rec 6very operations and sufficient distance from the plant to enhance habitability."
In order to i
meet this criteria a dedicated HVAC system comprised of HEPA and j
charcoal filtration was installed for the EOF.
The existing shielding was suf ficient for meeting the personnel dose criteria identified in NUREG 0578.
The total habitab i
the Emergency Operations Facility is 3100 fd.le area dedicated to 1
This crea includes a ' displ ay' area, NRC office, PECO office, conference area, i
i
' records area,. toilet: facilities, telephone equipment room, and l
four-undesignated office areas for support personnel.

'l
. t
.c Page 3 The location of the Peach Bottom TSC and EOF in the same building.has the distinct advantage of enhancing the interface between personnel. assigned to these facilities,.and promotes greater flexibility in the availability and utilization of personnel in responding to an emergency.
NUREG.0696 and Generic Letter 81-10 recommends that Emergency Operations Facilities located within 10 miles of the plant meet the following criteria:
Habitability consisting of ventilation isolation a.
with HEPA (no charcoal).
b.-
Provide a backup EOF between 10 - 20 miles.
We have designed the habitability control system for the EOF so as to have the same radiological habitability as the control room under accident conditions.
Thic includes a ventilation system with both high-efficiency particulate air (HEPA) and charcoal filters.
Based on the habitability design for the Peach Bottom EOF that exceeds-the criteria of Generic letter 81-10 and NUREG 0696, we hereby request exception to the requirement to provide a backup EOF.
