Resolution of Generic Safety Issues: Item B-36: Develop Design, Testing, and Maintenance Criteria for Atmosphere Cleanup System Air Filtration and Adsorption Units for Engineered Safety Features Systems and for Normal Ventilation Systems ( NUREG-0933, Main Report with Supplements 1–34 )
This NUREG-04713 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 1.52208 and BTP ETSB 11.211 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.
Criteria developed as a result of this issue have been documented412 in Regulatory Guide 1.52,208 Rev. 2, issued in March 1978 and in Regulatory Guide 1.140,209 Rev. 1, issued in October 1979. Thus, this item has been RESOLVED.
