I l 3.0 Purpose and Discussion 1
I 3.1 This procedure provides guidance and outlines required as well as recommended actions to be taken if a fire occurs in the UFTR Security Area (Building 557, Zone 1).
3.2 Definitions
3.2.1 A major fire is a fire which cannot be controlled or extinguished using equipment l permanently assigned to or installed in Zone 1 (Security Area). j 3.2.2 A minor fire is a fire which can be controlled or extinguished using equipment permanently assigned or installed in Zone 1.
3.2.3 Controlling a fire means that the fire can be inhibited to the point where it is possible to stop the source of the fire (e.g., de-energize an electrical supply or secure a source of Hammable liquids) so that the fire can be extinguished.
3.2.4 A control room fire is a fire that occurs in the control room; the significance of a control room fire is that spreadable radioactive contamination is not considered likely because the control room is not considered a radiologically restricted area for the ,
purpose of firefighting. This assumption should be verified after the reactor cell is secured from the fire.
3.2.5 A reactor cell fire is a fire in the Security Area outside of the control room, and therefore spreadable radio'etive contamination must be considered to be a significant possibility, more or less .cly depending upon where the fire is located and what is burning.
3.3 Permanently assigned or installed fire fighting equipment in the Zone 1 Security Area includes:
3.3.1 In the control room; 3.3.1.1 A CO fire 2 extinguisher placed under the control console apron, 3.3.1.2 An alarm (Pull) station on the South Wall of the control room.
3.3.2 In the reactor cell; 3.3.2.1 A CO extinguisher 2 near the airlock door.

SOP-B.2 PAGE 3 OF 12 3.3.2.2 A CO extinguisher 2 near the sink in the northwest corner of the cell.
3.4 Equipment immediately available to fire-fighting personnel but not in the Security Area (7one 1) includes:
3.4.1 A dry chemical fire extinguisher in the hose station outside the control room door I (Zone 2); '
3.4.2 A fire hydrant in the hose station outside the control room door (Zone 2);
3.4.3 Emergency breathing apparatus at the Emergency Support Center in the Counting Rooni (Room 106, NSC);
3.4.4 An alarm (pull) station on the west wallinside the lower reactor building access door (Zone 2).
4.0 Limits and Precautions 4.1 If the automatic fire alarm system actuates, the reactor shall be secured if the alarm is i
determ ned to be valid. Simple activation of the automatic fire alarm system does not require the reactor to be secured. However, status of the alarm (valid or not) must be determined immediately by the qualified second person or other responsible personnel; otherwise, the alarm shall be considered valid anc' 9e reactor secured.
4.2 The automatic fire alarm system may be actuated for tests while the reactor is operating without requiring the reactor to be tripped. The operator should be warned of the test before the test is begun.
4.3 If the stack exhaust monitor indicates a significant level as the emergency begins, subsequent trip of cell ventilation and reactor vent system may necessitate the use of emergency breathing apparatus as Argon-41 exfiltrates from the reactor into the cell.
4.4 Any time a fire is detected, it should be reported to the fire department through the University Police Department (2-1111) whether their assistance is required or not for two reasons:
4.4.1 First, even a minor fire can flare into a major fire with no warning or produce conditions that could incapacitate personnel on the scene with little or no warning; therefore, off-scene personnel should be made aware that there are people in a potentially hazardous situation (further, it is advisable to make provisions for a subsequent report that the person on the scene has extinguished the fire and is not a casualty).
4.4.2 Second, the automatic fire alarm system may trip, indicating a condition requiring fire department action at the fire and security computer console; REV 9,1/95 TCN: 8/97

I SOP-B.2 PAGE 4 OF 12 4.4.2.1 If the fire is under control by the judgement of a reactor operator or other j responsible individual, the University Police Department should be so informed, l and ,
l 4.4.2.2 If the assistance of the fire department is required, UPD should be made aware l of conditions and personnel on the scene. i 4.5 Any fire that causes ' damage to licensed material or the uncontrolled or unexpected release of radioactivity requires prompt notification to the Nuclear Regulatory Commission; damage to certain reactor systems and components also requires prompt notification to the NRC per the UFTR Technical Specifications, Security Plan and Emergency Plan. After the facility has been secured from any fire, the Reactor l Manager or a duly authorized representative shall immediately be informed so that I required followup action may be determined based upon NRC regulations, the UFTR Security Plan and the UFTR Emergency Plan.
4.6 All fires causing facility damage, personnel injury or personnel contamination or radiation exposure should also be promptly reported to the American Nuclear Insurers. l 4.7 All fires in the UFTR restricted area, regardless of classification, require that an i Emergency Action Fire Evaluation Form (UFTR SOP-B.2A) be properly completed as a record of the event.
4.8 Fire Department personnel have been instructed not to enter the Security Area (Zone 1) of the UFTR complex except under the direction of reactor personnel or radiation control pt:rsonnel. l 4.9 The use of water should be minimized for extinguishing a fire in the reactor cell because l I
of potential harm to the core, the fuel pits, graphite, or the primary equipment pit as well as potential to spread contamination. However, the primary objective must be to i extinguish the fire. ;
i 4.10 Debris should not be removed until such time as it can be verified that the material cor.tains no radioactive contamination or unless proper radiological precautions are taken.
4.11 The decision on the proper followup actions to be taken following any fire in the reactor j cell should take into account ALARA considerations.

7.2.2.3.1 Assuring the cell / control room doors are secured to limit access; 7.2.2.3.2 Make prompt notification to the Reactor Manager and the Radiation Courol I Officer or their alternates of the event and estimated consequences and current !
status; I l
7.2.2.3.3 Check of the area involved for radiation and contamination levels as well as l possible radiation / radioactivity hazards; this activity should be conducted under the direction of the Senior Reactor Operator-on-call or other SRO if the reactor has not been operating with the assistance of a Radiation Control i representative; )
NOTE: In the event no SRO is available, the Sc ior UFTR staff member will assume control as for radiological emergencies, j l
7.2.2.3.4 Making a decision on two choices for further immediate course of action:
7.2.2.3.4.1 Actuate the evacuation alarm and begin implementing UFTR SOP-B.1 (Instructicus for Radiological Emergencies);
7.2.2.3.4.2 Begin implementing recovery operations.
7.2.3 If, at any time, an evaluation indicates a minor fire requires reclassification to a major fire, then Section 7.2.4 becomes applicable.
7.2.4 For major fires; 7.2.4.1 Quickly note reactor cell and control room conditions to include:
7.2.4.1.1 APD (AIM 3BL) needle indicator position (upscale, midscale, downscale) and trend as well as APD (AMSS) indication and trend; 7.2.4.1.2 Stack exhaust count rate level and trend; 7.2.4.1.3 Neutron level trace on 2-pen recorder if operating; 7.2.4.1.4 Where (if possible) the flame or smoke is located.
7.2.4.2 Actuate evacuation alarm (air handler is automatically secured), if not previously tripped; actuate building fire alarm at the pull station in the Control room (South Wall) or on the West Wall inside the lower reactor building access door; 7.2.4.3 De-energize electrical power to affected equipment (see appendix II of this procedure for a list of the power supplies for equipment in the Security Area Zone 1 (Reactor Cell and Control Room));
