- The field tests for bypass leakage across ,the SGTS charcoal adsorber and 4
i HEPA filter banks are performed at a flow rate of 3000 s 105 cfa. This flow
, rate corresponds to the maximum overall three sene inleakage rate of 3264 cfa.
i . The SGT5 filter train pressure drop is a function of air flow rate and j
. . .. filter-conditions.-Surveitlance-testing is performed using either. the SGTS or ..
j drywell purge fans to provide operating, convenience. - Each reactor enclosure secondary containment zone and refueling area secondary containment zone is testad independently to verify the design leak j tightness. A design leak tightness of 1250 cfm or less for each reactor *
! enciesure and 764 cfm or less.for the refueling area at a 0.25 inch of vacuus
! water .; age will ensure that containment' integrity is maintained at an ! acceptable. level ifcall sones are connected to the SGTS at the same ties. y . " .., t u:r .. The post-LOCA offsite' dose ^ analysis assuees a reactor enclosure secondary containment post-draw down leakage rate of 1250 cfm and certain post-accident X/Q values. While the post-accident X/4 values represent a statistical inter-j pretation of historical meteorological. data, the highest ground level wind speed which can be associated with these values.is 7 aph (Pasquill-Gifford ' stan111ty Class G for a ground level release). Therefore, the surveillance-requirement assures that the reactor enclosure secondary containment is verified _ ! under meteorological conditions consistent with the assumptions utilized in the design basis analysis. Reactor Enclosure Secondary Containment leakage tests e j tnat are successfully performed at wind speeds in excess of 7 aph would also ; i satisfy the leak rate surveillance requirementsi since it shows compliance i with more conservative test conditions. e i 3/A.4.6 PRIMARY CONTAINMENT ATMOSPMERE CONTROL !,' l The OPERASILITY of the systems required for the detection and control of I hydrogen combustible sixtures of hydrogen and oxygen ensures that these systems l will be available to maintain the hydrogen concentration within the primary
- containment below the lower flammability limit during post-LOCA conditions.
The primary containment hydrogen recombiner is provided to maintain the oxygen concentration below the lower flammability limit. The combustible gas analyzer i is provided to continuously monitor, both during normal operations and post-LDCA, ! the hydrogen and oxygen concentrations in the primary containment. The primary i containment atmospheric mixing system is provided to ensure adequata sizing of the containment. atmosphere to prevent localized accumulations of hydrogen and i oxygen from exceeding the lower flammability limit. The hydrogen control 1 system is consistent with the recessendations of Regulatory Guide 1.7, " Control 1 of Combust ble Gas Concentrations in Containment Following a LOCA." March 1971.
