4 NRC COMMENTS ON GENERAL PROJECT DESIGN CRITERIA REVISIONS 2 and 3 Section Comment 2.5 Safety-related should not be limited to permanent plant features. The Mini-Decay Heat Removal System has operability requirements in the Proposed Tech Specs and should be it.terpreted as being safety related. Also,

future systems may be installed that are not permanent but are safety related. Delete the word permanent.

2.6 Items that assure the integrity of the reactor coolant pressure boundary but are not required to maintain the plant in a safe shutdown condition should be item "d."

Examples would be the Standby Pressure Control System and SDS when in the RCS processing mode.

3.2.7 It was agreed per your Documentation of Verbal Communication Form dated August 31,1982 (Byrne to Lynch) that words should be added to this section stating that the river flow rate for assessing actual releases from TMI-2 should be obtained exclusively from the USGS gaging station at Harrisburg, PA.

This requirement should be added as paragraph 3.2.8.

3.4.1 (L)

The Appendix R criteria should be retained.

Exemption has not to date been granted and even when approved, it will apply only to certain requirements of Appendix R.

Table 1 Item 3 Justify the deletion of. Reg. Guide 1.26 (Quality Group Classifications).

Item 4 Justify the deletion of Reg. Guide 1.29 (Seismic Design Classification).

Item 7 Justify the deletion of Reg. Guide 1.63 (Electrical Pene-tration Assemblies in Containment.....).
