c. Demonstrate for each of the ESF systems that a laboratory test of a sample of the charcoal adsorber, when obtained as described in Regulatory Guide 1.52, Revision 2, shows the methyl Iodide penetration less than the value specified below when tested in accordance with ASTM D3803-1989 at a temperature of s 30°C and greater than or equal to the relative humidity specified below.

ESF Ventilation System Penetration RH Annulus Ventilation <4% 95%

Control Room Area Ventilation < 0.95% 95%

Aux. Bldg. Filtered Exhaust <4% 95%

Containment Purge (non-ESF) <6% 95%

Fuel Bldg. Ventilation <4% 95%

• The Penetration bypass acceptance criteria for the charcoal adsorber for the 2B ABFVES train Is changed to 0.20%. This will remain In effect until the next Unit 2 refueling outage In the spring of 2006.
