PRAIRIE ISLAND NUCLEAR GENERATING PLANT EOF EMERGENCY PLAN IMPLEMENTING PROCEDURES 1.0 PURPOSE This procedure specifies the actions to be taken if the EOF must be evacuated and the EOF functions transferred to the Backup EOF.
2.0 APPLICABILITY This procedure is applicable to the Emergency Manager, RPSS, Technical Support Supervisor, and the EOF Coordinator.
3.0 PRECAUTIONS 3.1 An evacuation of the EOF may be necessary due to the existence of a conventional hazard, e.g., fire in EOF, loss of power, hazardous gases, etc.
3.2 Radiological conditions requiring an evacuation of the EOF may vary significantly based on the extent of operations in progress, the severity of the radiation levels, the estimated time that the radiation levels will be significant, and the integrated dose to personnel.
3.3 Non-essential personnel (i.e., those not directly involved in the activities of the EOF organization) should be evacuated first from any areas that exhibit elevated radiation or contamination levels. These personnel would include vendors, consultants, and public employees of the state and local agencies.
4.0 RESPONSIBILITIES The Emergency Manager has the overall responsibility to direct and coordinate an evacuation of the EOF and will be supported directly by the RPSS and the EOF Coordinator.
5.0 PREREQUISITES Radiological or conventional hazards exist in the EOF such that personnel are at risk to remain in the emergency center or the EOF has lost its functionality.
6.0 PROCEDURE 6.1 Emergency Manager SHALL:
6.1.1 Direct the EOF Coordinator and the RPSS to provide status reports of the EOF environment.
6.1.2 Refer to F8-6, Radiological Monitoring and Control at the EOF, for protective action guidelines for EOF personnel.
6.1.3 Ensure nonessential personnel (vendors, consultants, and state/local employees) are evacuated from the EOF if there is a high potential for a hazardous environment.
Page 2 of 8
PRAIRIE ISLAND NUCLEAR GENERATING PLANT EOF EMERGENCY PLAN IMPLEMENTING PROCEDURES
" The need to evacuate emergency response personnel for radiological reasons should be determined based on the following considerations:
1 The integrated dose that these personnel would receive if they remained in a radiation area.
- 2. The potential loss of the ability to utilize key technical personnel due to radiation exposure limits.
S3. The effectiveness of the emergency organization
-. :*/ operating in a condition of reduced mobility or communication due to use of protective clothing and equipment.
S 4. The potential exposure received during evacuation as compared to the potential exposure received by not evacuating.
6.1.4 If it becomes necessary to evacuate the EOF and time is available for a direct transfer to the Backup EOF, request that another Emergency Manager designee establish an EOF organization at the Backup EOF within the estimated evacuation time constraints. See Attachment A, Directions to the Backup EOF.
- -.- ~ A new EOF organization should be staffed and functional at
-- TE* *,'Jt the Backup EOF before the EOF is evacuated, if conditions permit.
6.1.5 If time is NOT available for a direct transfer to the Backup EOF (i.e., the EOF must be evacuated before the Backup EOF can be staffed by EOF personnel), transfer the EOF functions back to the TSC until the backup EOF is staffed.
A. Notify the Emergency Director of the need to quickly evacuate the EOF and the necessity of the TSC to temporarily receive the EOF offsite functions.
I/NOTE.
... ~
....,,.whenThe TSC will transfer the EOF functions to the Backup EOF facility is staffed by EOF personnel.
B. Consider the option of bussing the current EOF staff to the Backup EOF as opposed to setting up a new EOF staff.
Page 3 of 8
PRAIRIE ISLAND NUCLEAR GENERATING PLANT EOF EMERGENCY PLAN IMPLEMENTING PROCEDURES 6.1.6 Ensure the Emergency Director is informed of the EOF evacuation to the backup EOF.
6.1.7 Direct the RPSS to determine the evacuation route that would limit I exposure and provide a means of monitoring personnel evacuating the EOF.
6.1.8 Direct the EOF Coordinator to prepare for evacuation by arranging for transportation of personnel, as appropriate.
The EOF organization at the Backup EOF should be ready to assume the EOF offsite functions when:
- 1. Plant status has been determined and is being tracked.
- 2. The MIDAS and ERCS are functioning and all necessary communication equipment is functioning.
- 3. Offsite communication links to state and local government are functioning.
6.1.9 When the Backup EOF is prepared to receive the EOF offsite functions, perform an orderly turnover of the following EOF operations to the Backup EOF.
I A. Offsite Communications B. Offsite Dose Assessment and Field Team Monitoring C. Reclassification and Offsite Protection Action Recommendation authorizations The Backup EOF should inform the NRC, TSC, state and N,0TE:6;; local governments of the change of EOF location.
Page 4 of 8
PRAIRIE ISLAND NUCLEAR GENERATING PLANT EOF EMERGENCY PLAN IMPLEMENTING PROCEDURES 6.2 EOF Coordinator SHALL:
6.2.1 When informed of the decision to evacuate the EOF, supervise the assembly of materials and equipment to be removed from the area.
Z'*
- Materials may be contaminated and thus may not be able to E :i> , 7*
.be l removed. Everything that cannot be removed should be
- secured in a locked area.
Consider assembling and transferring the following material. Don't delay if material cannot be assembled.
A. "Plant Flow Diagrams" (one set exists at Ren Square 10th floor reference library)
B. "Logic Diagrams" (one set exists at Ren Square 10th floor reference library)
C. "Controlled Drawing File Index" (drawing aperture cards are located at 414 Nicollet Mall)
D. Cellular phone for EM and/or EOF Coordinator (used for communications in transit to Backup EOF) 6.2.2 Upon evacuation of the EOF, the EOF staff may be required to go to the Backup EOF to augment the Backup EOF staff members. Direct the Asst.
EOF Coordinator to arrange for transportation of personnel and equipment.
6.2.3 Contact each Sheriff's Department and inform them of the departure to the designated offsite assembly area or monitoring and decontamination facility.
6.2.4 Transfer your offsite responsibilities to the backup EOF (or TSC if necessary) as directed by the Emergency Manager.
Page 5 of 8
PRAIRIE ISLAND NUCLEAR GENERATING PLANT EOF EMERGENCY PLAN IMPLEMENTING PROCEDURES 6.3 RPSS SHALL:
6.3.1 When informed of the decision to evacuate the EOF determine possible evacuation routes that would limit exposure of personnel while enroute to the Backup EOF or an offsite monitoring and decontamination facility.
A. Selection of the offsite assembly area or monitoring and decon center will depend on various factors such as wind direction, weather conditions, and availability of the site. The following guidelines are used to assist in the selection of an assembly area or offsite monitoring and decon center:
- 1. Selected site should be upwind from any release.
- 2. Selected site should be accessible.
- 3. Evacuation routes to the selected site should minimize the time personnel would be exposed to any offsite radioactive release.
B. Any one of the following offsite facilities may be utilized as an assembly area or offsite monitoring and decon facility.
NOTE: SEC notifies Red Wing Service Center Representative when we go to an Alert.
- 1. Red Wing Service (if used, monitoring and decon kits from the EOF will need to be transported to the facility for setup).
- 2. Goodhue County/City of Red Wing Monitoring and Decon Center at the Red Wing Fire Department.
- 3. Dakota County Monitoring and Decon Center in Hastings.
6.3.2 If a county monitoring and decon facility is chosen, contact the appropriate county to notify and coordinate the logistics of the facility's use.
6.3.3 Supervise the assembly of monitoring teams to help coordinate the monitoring and decontamination of personnel, as necessary, during the evacuation.
6.3.4 Identify a collection point for Field Team samples to be transferred to a Monticello sample courier.
Page 6 of 8
PRAIRIE ISLAND NUCLEAR GENERATING PLANT EOF EMERGENCY PLAN IMPLEMENTING PROCEDURES 6.3.5 Contact the Monticello Plant to arrange for a sample courier to pick up samples at the collection point and return them to the Monticello lab for analysis. Possibly, the helicopter service could be used for this courier service (see F8-4).
6.3.6 Transfer your offsite responsibilities to the Backup EOF (or TSC if necessary) as directed by the Emergency Manager.
6.4 The Technical Support Supervisor SHALL:
Supervise the transfer of Technical Support personnel to the Backup EOF.

PRAIRIE ISLAND NUCLEAR GENERATING PLANT EMERGENCY PLAN IMPLEMENTING PROCEDURES 5.0 PROCEDURE 5.1 Steam Release Activity 5.1.1 IF the ERCS is obtaining steam release data, THEN obtain the steam line dose rates and the steam rad'release rate from the ERCS as follows:
A. At the TOC (Turn On Code), enter "GRPDIS STM-RAD" to gain access to the STM-RAD group of parameters.
B. The display will respond with a list of the points along with the prompt: ENTER UPDATE RATE IN SEC (5-1800). Enter the desired update interval, and then press <RETURN>.
C. Log Loop A & B Rad Level on Part I of PINGP 783.
D. Log Radiation Release Rate in pCi/sec on Part I of PINGP 783 (ERCS Rad Release Rate is already converted to pCi/sec Xe-133 Equiv.)
E. Go to Step 5.1.7.
5.1.2 If the ERCS is unable to provide steam release data, request an RPS to obtain the steam line dose rates in accordance with F3-20.1; or read R51 and R52 Rad Monitors local readout located in Train A Event Monitor Room (via 112 Bus Room). Log results on Part II of PINGP 783.
A. Using the time since reactor shutdown, obtain the Dose Rate Concentration Conversion Factor (IDE) from Figure 1, Figure 2 or Figure 3.
B. Calculate the noble gas release concentration, ItCi/cc Xe-133 equivalent, by multiplying the steam line monitor dose rate (mR/hr) times the dose rate concentration conversion factor ([tCi/cc/mR/hr).
Page 3 of 18
PRAIRIE ISLAND NUCLEAR GENERATING PLANT EMERGENCY PLAN IMPLEMENTING PROCEDURES 5.1.3 Determine if a steam release is occurring thru the Safety Relief Valves, PORV's, Dump Valves or SDAFW Pump Turbine Exhaust.
A. If the Power Operated Relief Valves (PORV's) are not closed:
- 1. Estimate the fractional opening of the PORV (0-1). Assistance from the Engineering Technical Group may be required as appropriate.
- 2. Determine each PORV flow rate as follows:
Flow Rate (CFM) = (3500)(L) where L = fractional opening B. If the dump valves are not closed:
- 1. Check the position of the MSIV's. If both closed, no release should be occurring. If open, continue.
- 2. Estimate the fractional opening of the dump valves, L, (0-1).
Assistance from the Engineering Technical Group may be required as appropriate.
- 3. Calculate each dump valve flow rate as follows:
Flow Rate (CFM) = (6400)(L) where L = fractional opening (0-1)
C. If any of the safety relief valves are not closed:
- 1. The REC should request engineering to calculate each safety relief flow rate.
- 2. If the safety is known to be full open, a default flow of 6000 cfm may be used.
D. If Steam Driven Aux Feedwater Pump is in operation on contaminated steam from faulted steam generator, use a steam exhaust flow rate of 150 cfm as a maximum flow rate.
Page 4 of 18
PRAIRIE ISLAND NUCLEAR GENERATING PLANT EMERGENCY PLAN IMPLEMENTING PROCEDURES 5.1.4 Determine the total steam release rate by summing the PORV, dump valve, safety valve, and Steam Driven Aux Feedwater Pump flow rates.
5.1.5 Ifthe SG's are flooded and water is relieving thru the PORV's, dumps or safeties, use engineering judgment to determine the flow rate., Use the estimated SG tube break flow rate. Consider using SI and Charging flow rates to be the flow rate through the SG tube break. Assume all the liquid flashes as it leaves the PORV's, dumps, or safeties.
5.1.6 Determine the noble gas release rate (Xe-1 33 Equiv [tCi/sec) by multiplying the noble gas concentration by the total steam flow per Part IV of PINGP 783.
5.1.7 Determine the iodine release rate or concentration as follows:
A. Obtain the SG wide range level (%).
- 1. If the SG level
- 85%, use 0.001 as an iodine/noble gas ratio.

Page 3 of 11.
PRAIRIE ISLAND NUCLEAR GENERATING PLANT EMERGENCY PLAN IMPLEMENTING PROCEDURE 5.2 Discussion Once a security threat (i.e., bomb threat, adversary threat, etc.) is determined to be a HIGH credible security threat, the definition of an ALERT is met and an ALERT should be declared per F3-2, Classifications of Emergencies.
Once a security threat (i.e., bomb threat, adversary threat, etc.) is determined to be a LOW credible security threat, the definition of a NUE is met and a NUE should be declared per F3-2.
The duty operations Shift Manager remains in charge of the overall plant response to the security threat with assistance from Plant Security, Operations, Local Law Enforcement Agencies (LLEA) and Nuclear Management Company (NMC) staff.
If changing security or plant conditions warrant escalation to a higher emergency classification, the Shift Manager is responsible to authorize the escalation.
Implementation of Emergency Plan procedures during a security event may need to be modified, depending on the event, in order to protect the safety of plant personnel, vital equipment, or protect the health and safety of the public.
6.0 PREREQUISITES 6.1 A credible security threat exists and; 6.2 A Notification of Unusual Event (NUE) or Alert has been declared.
Page 4 of 11
