Seal injection flow of 32 gpm is sufficient to satisfy the mimmum flow requirement.

The two-hour value is a very conservative assumption, based on a letter from the pump manufacturer, who states that the pumps can operate at flows as low as the design seal injection flow for days or weeks without senous effects (Gordom Parks of Bingham-Willamette to D H Stevens of Gilbert/Commonwealth, August 25, 1986)

Sheet 27 FOOTNOTES The initiation of the decay heat cooling system (DH) can occur anytime between 3 to 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> after an Appendix R fire For fires that require equipment repair before the DH system can be used, the 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> time limit applies. DH can be Initiated any time the reactor coolant system temperature and pressure are suitable, which can occur any time after approximately 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> The 3 to 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> manual actions required for DH system operation are not required for hot shutdown

2. Study results show that only one motor-driven EF pump and one OTSG are required for cooling No corrective action is therefore required ifthe valve Is not open. Therefore, "No Limit" entries are used In the table See GPUN Memo 5520-85-0520, 10-01-85 released via DRF 038078, and the attached study by R W Moore, Babcock and Wilcox, 'Evaluation of Effects of Reduced or Delayed EFW Flow for Appendix R Requirements - TMI' 3 Main feedwater flow to the OTSGs must be stopped to prevent overcooling or overfeeding the OTSGs Ifeither the flow control valves or their stop valves cannot be closed quickly, the main feedwater pumps or the condensate pumps must be tripped to stop MF flow Therefore, "No Limit" entnes have been used In the Action Required table, since valve action cannot be taken 4 The letdown function will be used to ease reactor coolant system inventory and pressure control The letdown function is only absolutely necessary when the pressurizer heaters are not available and feed and bleed Is used for solid plant pressure control and when required, to reestablish pressurizer pressure control at the termination of HPI cooling All "Action Required" table entries relative to the letdown function show "4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />" for the time required to establish and maintain a letdown flow path While components are listed for various letdown flow paths and supporting equipment, only one path will be established, depending on available components.

5 The "2 Hr." values for MU-V-14 and MU-V-t6's are based on events for which emergency feedwater Is available, seal injection Is not required, and pressure control Is available, so that normal makeup Is not Immediately required Makeup can be delayed with the reactor In hot shutdown, for two hours Correction of spurious operation of MU-V-16A, B,C, or D, or 17. or 217 Is,however, required within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> during which the RCS enters Into "feed and bleed" condition An alternative means of correcting spurious opening of these valves Is to trip the makeup pump This Is acceptable so long as thermal barrier cooling Is available, so that RCP seal Injection Is not required

6. The Action Achievable column should be regarded as a conservative estimate, for all manual actions Implemented In the fire emergency procedures The Action Required column Is also a conservative estimate In most cases, an adequate margin can be shown without detailed analysis of the system and component operating sequences and times Action required times are supported by analysis as required

7. The Redundant Valves column refers, in most cases, to those valves which serve an equivalent function In a redundant train, and does not, In all cases, Identify valves which provide the required shutdown function for all Appendix R fire events 8 The "2 Hrs"'limit applies for the IB-FZ-3 and IB-FZ-8 fires for which HPI cooling is used, and Is a minimum figure based on the desirability of re-establishing EFW as soon as reasonably achievable, taking into account the time required to extlinguish the fire and gain manual control HPI can safely be used for a considerably longer period, and the reactor can, in fact, be cooled down on HPI and DHR-LPI alone See the following TMI-1 Abnormal Transient Procedures (ATPes)

ATP-1210-4 Rev 7 (06-13-86) "Lack of Primary to Secondary Heat Transfer" ATP-1210-6 Rev 6 (06-13-86) "Small Break LOCA Cooldown" ATP-1210-Rev 8 (06-13-86) "HPI Cooling - Recovery from Solid Operations" At least one of the EF-V-30 valves Is required immediately (I e , within 20 minutes) for EFW cooling (all zones except IB-FZ-3 and IB-FZ-8). The "20 Min "Action Required values are based on small-break LOCA analyses which show acceptable primary system response with neither high pressure Injection nor emergency feedwater available for 20 minutes after reactor trip. This situation occurs In two fire areas, FH-FZ-5 and CB-FA-2g, where the valve circuits can be promptly Isolated at the Remote Shutdown Transfer Switch Panel, and manually controlled using handwheels under direction of control room operators Also, loss of backup air supply due to a fire in IB-FZ-2 and DG-FA-2 leads to a similar situation (Ie, 20 Min Action Required) for the EF-V-30 valves In these fire areas they will be normally controlled using handwheels under direction of control room operators For the small-break LOCA analyses, see the reference under note 2, and GPUN-SDD-TI-211A, Rev 3, System Design Description, Div I, "High Pressure Injection System Cross Connect and High Capacity Makeup Valve, TMI Restart Task RM-14, B/A 412072" 9 The IC and NR valves are required to support thermal barrier cooling and letdown cooling Westinghouse has stated that reactor coolant pump seals will survive for 30 minutes with acceptable leakage, without thermal barrier cooling or seal injection (with the reactor coolant pumps tripped) For a running RC pump, this time limit is lowered to 10 minutes The 30 minutes manual operating time is based on events which requires thermal bamer cooling, the reactor coolant pumps are assumed to be tripped The next limit for operation of these valves would be 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />, for establishing letdown cooling Seal Injection is available In these cases

10. "No Limir applies to spurious opening of MS-V-3A, 3B, 3C, 3D, 3E, and 3F since it can always be corrected by closing MS-V-8A and MS-V-8B from the Control Room.

11. A combination of two Atmospheric Dump Valves (MS-V-4A/B) and three Turbine Bypass Valves (any three of MS-V-3B/CID/EIF) may be used to achieve cold shutdown conditions within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> for fires that require the evacuation of the Control Room. These combinations are identified In Calculation C-1i101-91 1-E6120-001, 'Appendix R 72 Hour Cold Shutdown Analysis'. Implementation Is addressed under guidance provided to the Technical Support Center (TSC) In "TSC Engineering Calculation Guide 15 0" This guidance will be used for Implementation ifthe plant requires an accelerated cool down to protect the reactor core from damage (cool down path reliability Issue) and with the understanding that condenser damage Is expected and acceptable Implementation also effects the habitability of the Turbine Building Valves MS-V-3A (Turbine Bypass Valve) may also be used but Is not relied on for achieving cold shutdown conditions based due to a different design than the other MS-V-3 valves Main Steam Safety Valves MS-V-17A/B/C/D, MS-V 18A/B/CID MS-V-19A/BICID MS-V-20A/BIC/D and MS-V-21AB (MS-V-2IA/B are a smaller size and would not make any significant contribution to cool down) are addressed in the calculation but are not used for this function since they are not designed for manual operation Rev 19 0031002 T3-2 27
