McGuire Units I and 2 16.5,1-1 Revision 115

Inventory Control-Reduced Inventory Operation 16.5.1 TESTING REQUIREMENTS None BASES Generic Letter 88-17 and NUREG 1410 involve concerns associated with a loss of Residual Heat Removal (RHR) during RCS reduced inventory. Numerous events have occurred in the industry that resulted in a loss of RHR during reduced inventory operation. This is of great concern due to the potential for substantial core damage occurring in a relatively short time period. This SLC depicts those commitments that are extremely important to nuclear safety, however, are not presently covered by Technical Specifications.

Under the stated APPLICABILITY, when EITHER steam generator nozzle dams are in use OR the RCS cold leg side is opened with total opening of one square inch or greater, a hot leg vent path is required. The vent path may be satisfied by:

1. Hot leg nozzle dam not installed on the vented loop AND Removal of either of the following on the vented loop:
a. Hot leg diaphragm and manway OR
b. Cold leg diaphragm and manway (with associated cold leg nozzle dam installed*)

OR

2. Reactor vessel head is removed.
  • Installation of the associated cold leg nozzle dam avoids diversion of makeup flow (injected via a cold leg nozzle) intended for the core.

McGuire Units 1 and 2 16.5.1-1 Revision 115

Inventory Control-Reduced Inventory Operation 16.5.1 TESTING REQUIREMENTS None BASES Generic Letter 88-17 and NUREG 1410 involve concerns associated with a loss of Residual Heat Removal (RHR) during RCS reduced inventory. Numerous events have occurred in the industry that resulted in a loss of RHR during reduced inventory operation. This is of great concern due to the potential for substantial core damage occurring in a relatively short time period. This SLC depicts those commitments that are extremely important to nuclear safety, however, are not presently covered by Technical Specifications.

Under the stated APPLICABILITY, when EITHER steam generator nozzle dams are in use OR the RCS cold leg side is opened with total opening of one square inch or greater, a hot leg vent path is required. The vent path may be satisfied by:

1. Hot leg nozzle dam not installed on the vented loop AND Removal of either of the following on the vented loop:
a. Hot leg diaphragm and manway OR
b. Cold leg diaphragm and manway (with associated cold leg nozzle dam installed*)

OR

2. Reactor vessel head is removed.
  • Installation of the associated cold leg nozzle dam avoids diversion of makeup flow (injected via a cold leg nozzle) intended for the core.

McGuire Units 1 and 2 16.5.1-1 Revision 115

Inventory Control-Reduced Inventory Operation 16.5.1 TESTING REQUIREMENTS None BASES Generic Letter 88-17 and NUREG 1410 involve concerns associated with a loss of Residual Heat Removal (RHR) during RCS reduced inventory. Numerous events have occurred in the industry that resulted in a loss of RHR during reduced inventory operation. This is of great concern due to the potential for substantial core damage occurring in a relatively short time period. This SLC depicts those commitments that are extremely important to nuclear safety, however, are not presently covered by Technical Specifications.

Under the stated APPLICABILITY, when EITHER steam generator nozzle dams are in use OR the RCS cold leg side is opened with total opening of one square inch or greater, a hot leg vent path is required. The vent path may be satisfied by:

1. Hot leg nozzle dam not installed on the vented loop AND Removal of either of the following on the vented loop:
a. Hot leg diaphragm and manway OR
b. Cold leg diaphragm and manway (with associated cold leg nozzle dam installed*)

OR

2. Reactor vessel head is removed.
  • Installation of the associated cold leg nozzle dam avoids diversion of makeup flow (injected via a cold leg nozzle) intended for the core.

NOTE ----------------------

Activities that could perturb the RCS during reduced inventory operation shall require prior notification of the operations shift manager.

APPLICABILITY RCS level < 60 inches (wide range) with irradiated fuel in the core.

REMEDIAL ACTIONS CONDITION REQUIRED ACTION COMPLETION TIME A. RCS not properly A.1 Initiate action to provide Immediately vented. the required hot leg vent path.

AND A.2 Suspend all activities that Immediately could perturb RCS level or which may reduce the reliability of the operating ND loop.

McGuire Units 1 and 2 16.5.1-1 Revision 115

Inventory Control-Reduced Inventory Operation 16.5.1 TESTING REQUIREMENTS None BASES Generic Letter 88-17 and NUREG 1410 involve concerns associated with a loss of Residual Heat Removal (RHR) during RCS reduced inventory. Numerous events have occurred in the industry that resulted in a loss of RHR during reduced inventory operation. This is of great concern due to the potential for substantial core damage occurring in a relatively short time period. This SLC depicts those commitments that are extremely important to nuclear safety, however, are not presently covered by Technical Specifications.

Under the stated APPLICABILITY, when EITHER steam generator nozzle dams are in use OR the RCS cold leg side is opened with total opening of one square inch or greater, a hot leg vent path is required. The vent path may be satisfied by:

1. Hot leg nozzle dam not installed on the vented loop AND Removal of either of the following on the vented loop:
a. Hot leg diaphragm and manway OR
b. Cold leg diaphragm and manway (with associated cold leg nozzle dam installed*)

OR

2. Reactor vessel head is removed.
  • Installation of the associated cold leg nozzle dam avoids diversion of makeup flow (injected via a cold leg nozzle) intended for the core.
