POINT BEACH NUCLEAR PLANT EPIP 10.3 EMERGENCY PLAN IMPLEMENTING PROCEDURES SAFETY RELATED Revision 6 POST-ACCIDENT CONTAINMENT HYDROGEN. March 26, 2003 REDUCTION 1.0. PURPOSE This procedure provides for the reduction of containment hydrogen concentrations in the post-LOCA environment.. This can be accomplished in two ways. The first method, detailed in Step 5. 1, provides guidance for the acquisition, installation, and operation of the Rockwell International Hydrogen Recombiner. The second method, which is detailed in Step 5.2, describes the. actions for directing the containment atmosphere from the containment to the Auxiliary Building ventilation system charcoal filter, F-23.
2.0 PREREOUISITES 2.1 Responsibilities 2.1.1 Operations is responsible for directing the containment atmosphere to the auxiliary building ventilation system under the direction of the OSC Coordinator and Rad/Chem Coordinator.
2.1.2 The Resource Coordinator at the EOF is responsible for making arrangements to have the hydrogen recombiner shipped to Point Beach Nuclear Plant.
2.1.3 The Maintenance and Operations group are responsible for the setup and operation of the hydrogen recombiner under the direction of the OSC Coordinator and Rad/Chem Coordinator.
l2.1.4 'Radiation Protection group is responsible for operation of Rad Monitors and operation of Isokonetic Sampling Sys.
2.2 Equipment 2.2.1 'Hydrogen Recombiner stored by the Pooled Inventory Management System (PIMS).
2.2.2 Auxiliary Building truck access.
2.2 3 Auxiliary Building Crane (both main and aux hoist).
2.2.4 MCC IB31.
2.2.5 Hydrogen Recombiner electrical and mechanical connections.
2.2.6 Training Installation Video tape #61.

POINT BEACH NUCLEAR PLANT EPIP 10.3 EMERGENCY PLAN IMPLEMENTING PROCEDURES SAFETY RELATED Revision 6 POST-ACCIDENT CONTAINMENT HYDROGEN March 26, 2003 REDUCTION 3.0 PRECAUTIONS AND LIMITATIONS 3.1 Hydrogen Recombiner 3.1.1l The hydrogen recombiner is a skid-mounted unit with a detached control cabinet. The unit has to be brought in from off-site; therefore, the Auxiliary Building truck access area must be-available.
3.1.2 The hydrogen recombiner must be placed on the El. 46' of the Auxiliary Building. This requires the use of the Auxiliary Building crane; therefore, the crane must be available. It is powered from MCC 1B3 1, which must also be available.
3.1.3 The hydrogen recombiner is stored in Memphis, Terinessee, so delivery will take 1-2 days.
3.1.4 All -electrical and mechanical connectors are on-site: No connectors come with the unit.
3.1.5 The unit may become highly radioactive (>500 R/hr) ahd ALARA considerations will need to be made.
3.1.6 The unit has an upper limit for hydrogen inlet concentration of 5%.
Reference Rockwell Component Iristruction Manual, 01398.
3.1i.7 If at any time during operation containment integrity must be established, valves H2 V-19, H2 V-20, H-V-22 and H2 V-23 must be manually shut.
Do NOT enter pipeways.
3.1.8 The recombiner and associated piping is pressure tested to 10 psig. Fission product release could occur if aligned when containment pressure is > 10 psig.
3.2 Directini The Containment Atmosphere To The Auxiliary Building Ventilation System
'3.2.1 Ensure Auxiliary Building ventilation exhaust is in operation prior to AND during venting operations.
3.2.2 Use respiratory protection as prescribed by -Radiation Protection when sampling and draining.
3.2.3 The valves in this system provide-containment integrity and must NOT be operated unless authorized by the Shift Manager (SM).
3.2.4 Containment venting must be stopped immediately should the operating Auxiliary Building ventilation exhaust fan, W30 or W21, trip.
