When the TSC is activated by the on-shift Site Emergency Director (SED), the on-call SED will obtain a turnover from the on-shift SED using Appendix B and report to the TSC. The SED shall be responsible for implementing this procedure, coordinating TSC activities, and overseeing the operations of the Operations Support Center (OSC).

3.2 Activation Methods The SED will activate the TSC by announcing the emergency condition by one or more of the following methods:

A. Emergency Paging System (EPS).

B. Operations Duty Specialist (ODS) activate EPS from the Central Emergency Control Center (CECC).

C. Plant Public Address (PA) announcement.

D. The Shift Manager or operations clerk will contact the persons designated on the REP Duty Roster and/or Call List.

PIP 6 3.3 Call Ust The Emergency Preparedness Manager (EPM) maintains a REP Duty Roster and Call List book listing key TSC personnel by name, plant and home telephone numbers. The REP Call List and Duty Roster book will be updated at least quarterly by the EPM or designee with input by the appropriate section/group supervisors.

3.4 Response Personnel The following personnel normally report to the TSC or the assigned TSC support location upon activation of the TSC by the SED. Additional replacement personnel will be called as replacements to establish 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months operations while typically maintaining a 12 hour1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months or shorter shift (excluding turnover).

SEQUOYAH ACTIVATION AND OPERATION OF THE TECHNICAL SUPPORT CENTER I EPIP61 3.5 TSC Relocation It is highly unlikely that the TSC will be required to relocate due to the physical and radiological protection provided by its location. However, should the SED determine that relocation TSC is necessary, an alternate location will be selected based on the following guidance:

A. Location should have adequate access to the plant (preferably is within the Protected Area), have a current radiological survey, be upwind from plant, and have adequate ventilation control.

B. Location should have adequate communications capabilities (including at least three telephone circuits).

C. Location should have physical space for at least 15 persons (may be divided into two areas - one for TAT and one for Command & Control).

D. Locations for consideration include:

Co-locating with the OSC

O&PS 1 Floor

Work Coordination Center

Sequoyah Training Center 3.6 Deactivation The TSC will be deactivated when directed by the SED. All TSC personnel as a part of deactivation will:

A. Ensure all assigned tasks and assignments are completed.

B. Ensure all emergency response teams have been debriefed.

C. Ensure all emergency equipment and supplies have been returned to their specified storage locations.

D. Collect and review all records for completeness and forward all records to the Emergency Preparedness Manager.

3.7 Procedure Adherence Normal plant maintenance procedures will be followed whenever possible.

Should a situation arise where normal procedures would be inappropriate, maintenance will be performed as determined by the OSC Manager.

§ SEQOY HI ACTIVATION AND OPERATION OF THE TECHNICAL SUPPORT CENTER EPIP -6 I APPENDIX G CONTAINMENT SUMP OPERATION AND LEVEL GUIDANCE Page 1 of 2 Part I Containment Level Information

1. The 11 percent containment level set point for switch over was specified to prevent an inappropriate automatic switch over to the containment sump for steam line breaks in the yard that could damage the RWST. Switch over, as required for a LOCA, is based on change in RWST level (i.e., volume of water injected). Based upon RWST Technical Specification limits and switch over setpoints, the actual sump level will be at least 63.5 percent (el. 693) at the time of switch over.

2. During the injection phase following a LOCA, the only function of the containment sump level instrumentation is to provide a permissive input for the switch over.

3. Until the inflow into the containment sump and the leakage out of it through the crane wall reaches equilibrium, the actual transient sump level could approach 90 percent. When instrumentation errors are considered, the sump level indication could go high off scale for a short period of time.

4. Actual equilibrium level in the containment sump is expected to be 63.5 percent (i.e., crane wall penetrations are sealed up to 63.5 percent, and more than enough water will be injected to reach this level; surplus water will flow into the area outside the crane wall). However, due to instrument inaccuracies, the indicated level could vary between 50 percent and 78 percent.

5. After the sump has reached equilibrium and temperature effects on instrumentation have stabilized, the indicated sump level should remain constant. Because the sump volume is large and will tend to mask small leaks, any significant trend showing an increase or decrease in level, however slow, should be investigated.

6. The containment sump is subject to vortexing, which could damage the pumps if the sump is operated at too low level. As long as the indicated level stays above 22 percent, the sump will operate as designed with full ECCS flow.

7. The limiting set point for sump operation at full flow (22 percent level) is based upon vortex prevention requirements.

8. If recirculation from the sump is required with a low sump level (less than 22 percent) following a large break LOCA, then the operator should be aware that vortex-free sump operation is no longer assured. If operation under these conditions is required, the probability of effective ECCS operation will improve if flow from the sump is reduced. Also, other system indicators (e.g., pump amps, pressure, and flow) should be monitored for signs of vortexing.

9. For near normal conditions (i.e., containment spray is no longer required and total flow from the sump is less than 11,000 galmin) the instrument inaccuracies are less than +/- 8 percent and a minimum indicated level of 18 percent will ensure vortex free sump operation.

10. Utilize the "External Leakage Rates" notebook, in the affected unit Control Room, to anticipate areas of potentially high dose rates when sump recirculation is initiated.

Page 40of 51 REVISION 37

SEQUOYAH l ACTIVATION AND OPERATION OF THE TECHNICAL SUPPORT CENTER IEPIP I - 6 1 APPENDIX G CONTAINMENT SUMP OPERATION AND LEVEL GUIDANCE Page 2 of 2 Part II Information on Blockage of Containment Sump Screens after establishing sump recirculation

1. MONITOR for indications of sump blockage. Transport of debris to the containment sump screens during sump recirculation could result in a flow restriction on the RHR and CS pump suction. Although significant sump clogging is not expected, the potential exists for loss of adequate NPSH resulting in loss of ECCS and CS flow.

EA-63-8, "Monitoring for Containment Sump Blockage," provides guidance for the MCR staff on monitoring ECCS and CS indications to detect the onset of sump clogging. The following may indicate sump screen blockage:

ECCS flow, discharge pressure, and motor amps gradually dropping (unexplained) or erratic/dropping to zero (if adequate NPSH has been lost).

Note that RCS pressure rising will cause flow and motor amps to decrease.

CS pump flow and motor amps gradually dropping or erratic/dropping to zero (if adequate NPSH has been lost).

2. IF indications of sump clogging are observed, THEN the following actions should be evaluated:

a. Evaluate reducing containment spray flow and/or ECCS flow by stopping one train. This is expected to slow the rate of debris buildup and will reduce the differential pressure across the sump screens. If containment pressure is not excessive, reducing CS flow to single train is preferred over reducing ECCS flow. Caution should be exercised since deliberately stopping one train of ECCS or CS may violate accident analysis assumptions (a subsequent single failure will result in complete loss of flow).

b. Evaluate the need for RWST refill to allow realigning pump suction to RWST.

Caution should be exercised prior to pumping an additional large water volume into containment due to the potential for containment flooding resulting in loss of instrumentation and eventual loss of containment integrity.

c. If sump clogging results in severely degraded flow, then evaluate the need for entry into ECA-1.1, "Loss of RHR Sump Recirculation." This ECA initiates actions to refill the RWST, allows reducing or stopping CS flow, initiates RCS cooldown/depressurization, and initiates RCS makeup from alternate source (normal charging).

d. Briefly stopping and then restarting all flow across sump screens (by stopping all ECCS and CS) may allow debris to fall off. (Screens are sloped to allow gravity to assist in debris removal). This action should NOT be recommended without carefully considering the impact on core temperatures and containment pressure.

b. In case of failure of the normal RHR suction valve FCV-74-1 to open, continue cooldown using the steam generators.

>,,.. ........ N ...... . . . ... . I . ...'t. ii0fytw

.. -hammer,must I becnsidered-.-Parametrs to c.Bonsider are cotainmet

c. Within one to four hours after event initiation, place at least two lower containment coolers in service. Ensure ERCW is aligned before placing coolers in service. This action will require entry into the annulus to manually open the ERCW valve if one train of power is lost. Preferably all lower containment coolers should be placed in service.

(1) If A-train power is lost, A-train valves FCV-67-1 04, FCV-67-1 12, FCV-67-83 and FCV-67-91, located in the annulus (approx. el. 690) will have to be manually operated in order to place the B-train EROW header to the B-train lower compartment coolers in service. See Appendix W, page 3, for the specific location of these valves.

(2) If B-train power is lost, B-train valves FCV-67-88, and FCV-67-96, FCV-67-99 and FCV-67-1 07, located in the annulus (approx. el. 690) will have to be manually operated in order to place the A-train ERCW header to the A-train lower compartment coolers in service. See Appendix W, page 3, for the specific location of these valves.

(3) The Temperature Control Valves (TCV's) for each Lower Compartment Cooler must be opened to obtain ERCW flow. The TCV's are operated from panel M-9 for Units 1 & 2 or can also be failed open from the Auxiliary Control Room via transfer switches.

d. Evaluate containment heat loads. If a reactor coolant pump is running, then at least three lower containment coolers should be in service.

Page 42 of 1 REVISION 37

ACTIVATION AND OPERATION OF THE IlEQUOYAH I TECHNICAL SUPPORT CENTER lP -6 APPENDIX H ERCW CONCERNS FOR TECHNICAL ASSESSMENT TEAM Page 2 of 2

e. ERCW gages are located in the 669 Penetration Room. Expect that each string of ERCW entering containment would require >400 gpm if all coolers in that string are receiving flow. Evaluate the ERCW flow to the lower compartment coolers and consider reducing flow to other equipment such as the containment spray heat exchangers if the required flow is not available.

(The system flow balance assumes that containment spray flow will be removed if the lower compartment coolers are used.)

f. In case of failure of both the CVCS letdown and excess letdown flow paths, then evaluate use of the reactor vessel head vent system or pressurizer PORV.

2. Monitor ERCW screens and strainers. Within 3 hours3.472222e-5 days 8.333333e-4 hours 4.960317e-6 weeks 1.1415e-6 months after an operating basis earthquake (1/2 SSE), a loss of downstream dam, a stage I flood, a tornado warning or within 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months following a LOCA, then perform the following actions

a. Isolate chlorination to ERCW.

b. Inspect ERCW traveling screens and place screens into continuous backwash.

c. Inspect ERCW strainers differential pressure and place into continuous backwash.

3. For events other than those listed in previous step, then maintain the normal monitoring and cleaning frequency of the ERCW screens and strainers per O-SO-67-3.

Air leakage results in an uncontrolled increase in containment pressure following a LOCA. Water leakage results in sump boron concentration dilution and a water level in containment above the design limit.

A HELB induced failure of an ERCW line in containment could result in loss of the LCCs which are needed to maintain acceptable long-term containment temperatures post-HELB. An alternate method of cooling containment under this scenario is to use the containment sprays to cool the air in the upper compartment and the air return fans (ARFs) to circulate this air from the upper compartment to the lower compartment. The fans/ductwork from the LCCs should be used to circulate this air throughout the lower compartment.

SEQUOYAH ACTIVATION AND OPERATION OF THE I e TECHNICAL SUPPORT CENTER I APPENDIX J CONTINGENCIES FOR CONTROL AND PROCESSING LARGE VOLUMES OF SECONDARY SIDE CONTAMINATED WATER Page 1 of 1 The method of processing large amounts of contaminated water in the secondary side of the plant due to a steam generator tube rupture will be determined by the Chemistry Lab, based on condensate samples for activity.

The preferred method is to process the water through the condensate D.l. Waste Regeneration System to the High Crud Tanks (HCT). The water can then be released to the release header using 0-SI-CEM-077-400.1 or O-SI-CEM-077-400.2. Reference flow diagrams 1,2-47W838-1 and 4.

If the contamination levels of the condensate are almost within limits for release, consideration should be given to using one of the condensate D.l. beds to reduce the activity level to a point that release using method one is possible. This will depend on the age and condition of the resins. Contact the WWPG manager or Technical Support Engineer for guidance.

If the contamination levels are high enough to prevent release, consider processing the water through a Demineralizer System similar to the Rad Waste D.I. being supplied by Chem Nuclear, under agreement contract #93N7B-79294A-000.

Two methods of D.l. operation are discussed here. The first being the best method.

METHOD 1 (PREFERRED)

Process the water through the condensate D.l. Waste Regeneration System. This will provide a flow path from the condensate system through a vendor supplied demineralizer system back to the unit hotwell through an open manway (vacuum will have to be broken).

This will allow recirculation of water from the condensate system of up to 200 gpm back to the hotwell until the activity levels are at a point that the water can be released to the HCrs, or after Chem Lab analysis indicates that it can be saved as condensate.

METHOD 2 (ALTERNATE)

Process water through a vendor supplied D.l. System to the HCTs and then release the HCT's to the release header, using O-SI-CEM-077-400.1 or 0-SI-CEM-077-400.2, as clean D.l. water. As this water is being removed additional make-up water will be required to maintain inventory in the unit hotwell.

1.0 PURPOSE This procedure gives guidance on terminating an emergency classification by the Site Emergency Director (SED) following staffing of the Emergency Response Facilities (ERFs), and the development of recovery procedures to efficiently utilize resources and keep radiation doses ALARA.

This procedure also provides a minimum list, in the form of a checklist, of the plant system parameters to be considered prior to termination of an emergency. A checklist of guidelines for development of a recovery strategy are also included.

These checklist should not be considered as all inclusive. They should be used only as a minimum basis, excluding the specifics of the event, for termination and recovery.

3.0 INSTRUCTIONS 3.1 Termination A. The decision to terminate an event where the ERFs are not staffed is the responsibility of the SM /SED.

B. The decision to terminate an event following staffing of the ERFs will be made by the SED after consultation with the plant technical and operations staffs and coordinated with the CECC Director. This decision will be based upon a comprehensive review of plant system parameters and completion of Appendix A, Termination Guidelines.

C. Should an emergency situation occur following the termination, the SED shall reactivate the Emergency Response Organization.

PAGE 4 OF 11 REVISION 5

3.2 Recovery A. The overall goal of the recovery effort is to assess the plant condition resulting from the emergency, perform clean-up and repair operations to restore the plant to a predetermined status.

B. The decision to enter the recovery phase will be made by the SED with concurrence from the CECC Director and the Senior Vice President, Nuclear Operations. Following the decision to enter into the recovery phase, the Senior Vice President, Nuclear Operations or his designee will direct the overall recovery effort.

C. If the recovery phase is expected to be a long-term process, he may form a team to be responsible for continuous control of the recovery operation. The organizational structure of such a team would be contingent upon the emergency situation and procedures required for recovery. The Local Recovery Center (LRC) is available to provide additional office space near the site for the recovery team at the discretion of the Senior Vice President, Nuclear Operations. See section 3.3 for information concerning the Local Recovery Center.

D. All major post accident onsite recovery measures shall be performed in accordance with written procedures.

E. Personnel protective measures shall be taken on initial entries and throughout the assessment and recovery operation to limit exposures As Low As Reasonable Achievable (ALARA) in accordance to SQN EPIP-1 5, Emergency Exposure Guidelines.

F. The State of Tennessee has the authority for actions taken offsite however, TVA will serve as an important source of technical and analytical assistance for the State in offsite monitoring and sampling. The Senior Vice President, Nuclear Operations, or his designee will serve as the State's contact for coordination of TVA's efforts in offsite monitoring, sampling and recovery.

SEQUOYAH TERMINATION AND RECOVERY EPIP-1 6 3.3 Local Recovery Center (LRC)

A. The purpose of the LRC, located at the Sequoyah Training Center (STC), is to provide a nearsite facility for TVA recovery management as well as NRC emergency response personnel and other emergency and/or recovery personnel.

B. The LRC provides adequate space for TVA and others who may locate there to support the site should additional office space near the site become necessary during the recovery phase.

C. The LRC will provide dedicated space for NRC personnel containing adequate supplies, communication, and data necessary for them to carry out appropriate functions.

See NP-REP, Appendix B for description.

3.4 Radiation Dose Management A. Radiological Control (RADCON) personnel will provide monitoring services and dosimetry and prescribe the protective equipment to be used during the recovery of personnel or equipment.

B. Before entry to the affected area is attempted, RADCON will estimate airborne and direct radiation levels in the recovery area. From the information obtained, respiratory protection and occupancy times will be established.

C. RADCON personnel will accompany the recovery personnel on the initial entry to confirm that the airborne radioactivity and radiation levels are as expected.

D. Dose for recovery personnel will be kept within the limits described in EPIP-15, and NP-REP. Respiratory protection factors given in EPIP-15 may be used in determining appropriate respiratory protection for the entry team.

E. TLD badges worn by recovery personnel will be processed by TVA. Process time for a badge would be approximately 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months .

F. Although an emergency situation transcends the normal requirements of limiting exposure, there are suggested levels in NP-REP and EPIP-1 5 for exposure to be accepted in emergencies. However, every reasonable effort to minimize exposure to ALARA would be made, even in emergencies.
