The U.S. Nuclear Regulatory Commission (NRC) is issuing for public
comment a draft guide in the agency's ``Regulatory Guide'' series. This
series was developed to describe and make available to the public such
information as methods that are acceptable to the NRC staff for
implementing specific parts of the NRC's regulations, techniques that
the staff uses in evaluating specific problems or postulated accidents,
and data that the staff needs in its review of applications for permits
The draft regulatory guide (DG), entitled, ``Preoperational Testing
of Emergency Core Cooling Systems for Pressurized-Water Reactors,'' is
temporarily identified by its task number, DG-1253, which should be
mentioned in all related correspondence. DG-1253 is proposed Revision 2
of Regulatory Guide 1.79, dated September 1975.
This guide describes methods that the NRC's staff considers
acceptable to implement Title 10, of the Code of Federal Regulations,
part 50, ``Domestic Licensing of Production and Utilization
Facilities'' (10 CFR part 50), Appendix A, ``General Design Criteria
for Nuclear Power Plants,'' with regard to preoperational testing
features of emergency core cooling systems (ECCSs) for pressurized-
water reactors (PWRs). This regulatory guide also describes methods
that the NRC staff finds acceptable for preoperational testing of ECCS
structures, systems, and components (SSCs), in accordance with the
regulations in 10 CFR part 52, ``Licenses, Certifications, and
Approvals for Nuclear Power Plants,'' Subpart B, ``Standard Design
Certifications,'' and Subpart C,'' Combined Licenses.''
