Criterion V of Appendix B to 10 CFR Part 50 states:
" Activities affecting quality shal? be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings.
Instructions, procedures, or drawings shall include appropriate quantitative or qualitecive acceptance criteria for determining that important activities have been satisfactorily accomplished" TVA Contract No. 77K31-820427, paragraph 3.0, " Applicable Codes and Standards",
includes Regulatory Guide 1.52.
Paragraph C.3.h in Regulatory Guide 1.52, Revision 2, requires water drains to be designed in accordance with ERDA 76-21.
Section 4.5.8 in EROA 76-21 states in part, "... When fire sprinklers are installed in the filter house, the drains must be sized to carry away the maximum sprinkler flow without water backup in the housing."
Contrary to the above, the drains in the standby gas treatment system charcoal adsorbers, furnished to the Hartsville.ad Phipps Bend nuclear units, were not sized to carry away the maximum fire protection system sprinkler flow without water backup (See Details, F.4.a.).
