Item B-36: Develop Design, Testing, and Maintenance Criteria for Atmosphere Cleanup System Air Filtration and Adsorption Units for Engineer

DESCRIPTION

This NUREG-0471[1]item involves developing revisions to current guidance and staff technical positions regarding ESF and normal ventilation system air filtration and adsorption units. This involves developing

revisions to Regulatory Guide 1.52[2]and BTP ETSB 11.2[3]to address technical advances that have shown that some current positions are unjustifiably conservative, some are unnecessary, and in some cases additional positions are necessary.

CONCLUSION

Criteria developed as a result of this issue have been documented[4]in Regulatory Guide 1.52,[5]Rev. 2,

issued in March 1978 and in Regulatory Guide 1.140,[6]Rev. 1, issued in October 1979. Thus, this item has been RESOLVED.
