- a. Letdown Rupture in the line The remote air-operated valve located near the main coolant loop is Line inside the reactor closed on low pressurizer level to prevent supplementary loss of containment coolant through the letdown line rupture. The containment isolation valves in the letdown line are automatically closed by the containment isolation signal initiated by the concurrent loss-of-coolant accident.
The closure of these valves prevents any leakage of the reactor containment atmosphere outside the reactor containment.
- b. Normal and See above The check valves located near the main coolant loops prevent alternate supplementary loss of coolant through the line rupture. The check Charging valve located at the boundary of the reactor containment prevents any Line leakage of the reactor containment atmosphere outside the reactor containment.
- c. Seal Water See above The motor-operated isolation valves located inside and outside the Return Line containment are manually closed or are automatically closed by the containment isolation signal initiated by the concurrent loss-of-coolant accident. The closure of that valve prevents any leakage of the reactor containment atmosphere outside the reactor containment.
- d. Letdown Rupture in the line Line outside the Any break between containment and the letdown heat exchanger containment would potentially result in flashing hot letdown fluid and would be identified by lo flow in the letdown line and other system indications.
The increase in letdown flow caused by a break downstream of the letdown flow indicator would be matched by an automatic increase in the charging flow and a HI Letdown Flow Alarm. An operational level in the pressurizer would, therefore, be maintained. Ultimately, the operator would be alerted by a Lo Lo level alarm in the volume control tanks. (Other indications would be an increased charging flow and falling volume control tank level. Also, the area monitors in the auxiliary building would detect any increase in activity). By observing the flow meter on the letdown line, the operator could detect the increase in flow, depending on the location of the break. The break could then be isolated by closing the redundant isolation valves in the letdown lines. Any spillage would be drained and collected in the Radioactive Waste Disposal System, while residual gases from any flashed coolant would be circulated through particulate filters before being discharged to the atmosphere through the plant vent.

- 1. Residual heat Rupture of a pump The casing and shell are designed for 600 psig and 400°F. The removal pumps casing pump is protected from overpressurization by two normally closed valves in the pump suction line and by a relief line, containing a relief valve, back to the pressurizer relief tank.
The pump is inspectable and is located in the auxiliary building protected against credible missiles. Rupture is considered unlikely but in any event the pump can be isolated.
- 2. Residual heat Pump fails to start One operating pump furnishes removal pump half of the flow Removal pump required to meet design cooldown rate. Failure of the other pump to start increases the time necessary for plant cooldown.

- 5. Remote Valve fails to open In the improbable event that one of the remote operated valves operated valves on the suction line to the residual heat removal pumps is inside inoperable, an attempt will be made to open it manually. If this containment in is impossible, the plant will be cooled to about 280 °F with pump suction steam dump from the team generators, and kept at that line temperature for several weeks until decay heat could be matched by the letdown heat exchangers and by feed and bleed.
Feed and bleed through the CVCS will done intermittently to prevent heat transfer through the regenerative heat exchanger.
The pressurizer level will be to minimum during the bleed operation and to maximum during the feed operation. It is estimated that plant cooldown be accomplished within a month.
- 6. Remote Valve fails to open Pump discharge pressure gage shows pump shut-off head operated valves indicating no flow. An alternate return line may be opened inside and utilized to direct flow to the RCS.

The values in this table are for the operating point described. Plant procedures may consider uncertainty as appropriate. See Section 9.5.
2 Cooldown refers to the operation that takes the reactor plant from hot shutdown (350 °F) and pressure to cold (140 °F) conditions. Once below 200 °F, which will preclude boiling, the CCW flow to the RHR heat exchanger may be reduced to accommodate the reduced RHR heat load.
3 The flows shown reflect the use of one safeguard's train. The second safeguard train may be placed in service provided the necessary equipment is operable. Single train operation results in minimum safeguard's requirements and a minimum cooldown.
4 This path is normally valved off with no flow through the path.
5 The flow through this path satisfies the miniflow requirements for the CCW Pump; there is no RHR heat load on CCW during LOCA injection.
6 UFSAR Chapter 14.3.4, Containment Peak Pressure Transient, input assumption #21, provides the explanation of this input to the containment accident analysis of record.
7 Flow to the SI PP Hx and CTS PP Hx is not specified during the Normal or Cooldown mode since the SI PP and CTS PP are not required to operate during these modes of operation. However, the flow paths to the SI PP Hx and CTS PP Hx are open to permit flow.
8 Flow to the SI PP Hx and CTS PP Hx is not specified during the Normal or Cooldown mode since the SI PP and CTS PP are not required to operate during these modes of operation. However, the flow paths to the SI PP Hx and CTS PP Hx are open to permit flow.

- 1. Component cooling water pump Rupture of a pump Isolate pump and start redundant pump. Minimum safeguards requirements only casing one out of two pumps.
- 2. Component cooling water pump Pump fails to start One operating pump will supply sufficient flow. Redundancy is sufficient to provide ample flow for any condition.
- 3. Component cooling water pump Manual valve on a pump This will be prevented by pre-startup and operational checks. Further, during suction line closed normal operation, each pump will be checked on a periodic basis, which would show that a valve was closed.
- 4. Component cooling water pump Stop valve on discharge Stop valve will be checked open by pre-startup and operational checks. The stop line closed or check valve and the check valve will be checked by periodic operation of the standby valve sticks closed pump during normal operation.
- 5. Component cooling heat exchanger Tube or shell rupture Isolate and valve in standby train.
- 6. Component cooling heat exchanger vent or Left open This will be prevented by pre-startup and operational checks. On the in service drain valve heat exchangers such a situation would be readily assessed by makeup requirements to system. On the out-of-service heat exchangers such a situation would be assessed during periodic inspection of general area.
- 7. Thermal Barrier Heat Exchanger Tube Leak or Rupture See Section 9.5.4 Detection by CCW Radiation Monitor or Surge Tank level.
Redundant containment isolation valves provide means to isolate if a leak is detected (isolation would require plant shutdown).

The flows shown reflect the use of one ESW train in service corresponding to one CCW safeguard's train. The second ESW train may be placed in service provided the necessary equipment is operable or the second CCW safeguard train is operating. Single train operation results in minimum safeguard's requirements and a minimum cooldown rate.

- 1. Normal Intake Dampers Failure to close Two dampers in series ensure isolation of outside air normal intake.
- 2. Pressurization/Cleanup Failure to open Parallel dampers ensure outside air intake Intake Dampers opens.
Fully open or One damper partially open is correct multiple dampers alignment. A single failure may result in open one damper fully open or 2 dampers partially open. Other failures are not considered credible.
- 3. Pressurization/Cleanup Failed to closed All air flowing through the filter is from Recirculation Damper position the intake and air cleanup is limited to a single pass. Control Room dose consequences may increase. The position of the recirculation damper is administratively controlled so it does not need to change position in response to a radiological accident.
