I. INTRODUCTION The punose of this report is to present the desip details of the Illinois Power Company Emergency Response Facilities (ERFs). These facilities include the Technical Support Center (TSC), the Operations Support Center (OSC), the Emergency @erations Facility (EOF) and the Backup Emergency Operations Facility (BEOF). This report describes the above facilities and how they meet the requirements of Supplement 1 to NUREG-0737, " Requirements for b rgency Response Capability". .

1 II. EMERGENCY RESPONSE FACILITIES (ERFs)

The purpose of the ERFs is to provide facilities from.which emergency response personnel can assist in the mitigation of the consequences of any accidents and respond to abnormal operating conditions which might occur at the Clinton Power Station. During emergencies, the ERFs will provide the following functions: l Assist the reactor operator in determining the plant safety status.

Relieve the reactor operator of peripheral duties and communications which are not directly related to the manipulation of reactor systems.

  • Prevent congestion in the Main Control Room (MCR). l Provide assistance to the operators from technical personnel who have access to comprehensive plant data.

Provide a coordinated emergency response by both technical and management personnel. ,

Provide reliable communications between onsite and offsite emergency personnel.

  • Provide a focal point for development of recommendations for offsite actions.

Provide relevant plant data to the NRC for its analysis of abnormal plant operating conditions.

A. Technical Support Center (TSC)

1. Purpose The purpose of the TSC is to provide the l following:

L

_i

a. A centralized and dedicated work area for management and technical support to station l operations personnel during emergency conditions.
b. Relief to the MCR operators of peripheral l duties and communications not directly related to reactor systems manipulations.
c. An area for designated support personnel to assemble in order to prevent congestion in the MCR. l
d. EOF functions during the ALERT Emergency Action Level Classification and initial EOF functions for SITE AREA EMERGENCY and GENERAL EMERGENCY classifications until the EOF is operational.
e. The primary station communications center during an accident or emergency condition.

The TSC is the emergency operations work area for the Station Emergency Director and designated technical, engineering, and senior licensee officials. The Station Emergency Director and his staff use the resources of the TSC to arovide guidance and technical assistance to tie Shift Supervisor. The TSC has the facilities to support station management and technical personnel assigned there during an emergency.

TSC personnel can analyze the station steady-state l and transient conditions during the course of an accident using the information available from the .

TSC data systems (see Section II.A.7). The l results of this analysis will be used to provide technical advice to the MCR operating personnel in l the handling of abnormal conditions and accident mitigation. TSC personnel will also use the environmental and radiological information available from the TSC data systems to perform offsite dose assessment calculations as well as other vital functions of the EOF until it is operational.

2. Staffing The TSC will be activated upon declaration of an ALERT, SITE AREA EMERGENCY, or GENERAL EMERGENCY.

Upon activation of the TSC, designated key personnel will report directly to the TSC and achieve full functional operation within one hour.

3. Location, Structure and Size The TSC is located on the 800' elevation of the Control Building, adjacent to the Unit 1 MCR. The location of the TSC relative to the MCR and OSC is shown in Figure 2.

'Although not a requirement, the TSC structure is seismic Category I. The TSC is supported by a 23 inch thick reinforced concrete slab and reinforced concrete beams and columns. The TSC has masonry l hollow concrete block walls with block wall column supports. All of the rooms in the TSC have an acoustical tile ceiling below the 17 inch thick reinforced concrete structural slab and a 6 inch reinforced concrete floor slab at the 825' elevation.. The slab at 825' elevation is supported by structural steel columns and beams which are coated with fireproof material. The TSC meets the same structural re uirements as the MCR to withstand earthquakes, hi h winds and floods.

Adjoining the TSC is the NRC Consultation Room and the Results Records Room (see Figure 2). These rooms support the TSC function and are included in the total floor space for the TSC. The combined area of the three rooms is approximately 1529 square feet. A description of each room is provided below,

a. Technical Support Center The TSC has an approximate area of 1,038 square feet. This is the primary work area for plant management and technical support .

Personnel when the EOF is activated, he facilitiac include communications, the Per-formance Monitoring System / Display-Control System (PMS/DCS) process computer system displays, offsite dose calculation equipment, a facsimile data transmitter (capable of transmitting information to the EOF and the NRC Operations Center in Bethesda, Maryland) and status boards,

b. NRC Consultation Room The NRC Consultation Room is approximately 233 square feet in area. This will allow l sufficient working space for three people.

Its primary function is to provide a private office space and a meeting room for NRC personnel.

l l

o

The NRC Consultation Room will normally be

- used by plant personnel for planning and l scheduling routine shift activities when the TSC is not activated.

c. . Results Records Room The area of the Results Records Room is-approximately 254 square feet. Current plant drawings and procedures used by shift personnel will be kept in this room.

The arrangement of the equipment in.the above rooms will incorporate changes as a result of human factors reviews and the experience of conducting drills.

4. Radiation Protection

^

a. Shielding The TSC is shielded by the same walls that shield the MCR. This desip meets the l requirements of General Design Critaria 19 of 10CFR50, Appendix A.
b. HVAC The TSC is within the MCR HVAC system boundary which is a safety grade system designed and constructed for highly reliable operation under emergency conditions.

During a high radiation condition the HVAC system automatically shifts to the high ,

4 radiation mode of operation. In this mode the normal outside' air intake (4000 cfn) is isolated and one of the two make-up trains and the recirculation train starts up'to remove particulates and adsorb radioactive iodines from minimum outside air (from 3000 cfm make-up train air intake). The TSC and MCR are kept at positive pressure to avoid

. radioactive air in-leakage.

c.- Local Radiation Monitoring Two safety grade radiation monitors at each primary and standby make-up air HVAC intakg l struegures detect gamma radiation from 10' to 10 mR/hr. These monitors will autamatic-ally initiate the high radiation mode of the 1
