3ackereunc Regulatory Guide i.39, Mcusekeeping Recuirements for '..'ater-C aled Nuclear P wer Plants", is being revised to res; nd to ;ublic cc::ents received on the guide. Copies of the c : ents and a discussion of these commencs is attached.

Sienificant Chance and its Value/~.:act Endorsement of Subdivision 3.2.3 of ANS~.415.2.3-1973 Public 'ce==ents were received that expressed c:nfusica cver the position in Revision 1 of Regulatory Guide 1.39 that endorsed both the guidelines and the require:2nts ir. Subdivision 3.2.3,.cire Prctection and Preventien, of ANSI "15.2.3-1973, "Heusekeeping During :he Cor.structica Phase of.'!uclear :: war ?! ants". One c::: enter questioned GC's endorsement of Subdivision 3.2.3 because it lacked specificity and provided li:tle useful guidance. Another cc = enter disagreed with iRC's endorsement of -he guideline en fire watches because he was concerned that this position would rec.uire fire watches during and i ediately folicwing all welding operations.

.Also, it was identified that the reference to the :'ational.:f re Codes in Subdivision 3.2.3 was incorrect.

. 'Je are in agreement witn tha c:mmen that Subdivisien 3.2.3 lacks specificity and rec gnize : hat other NR3 ;ublication:

present : re detailed guidance on fire protecticn and preven:icn..rurther, if the guideline on fire watches in Subdivision 3.2..? esere interpretad is requiring a fire watch for all welding operations, this position would conflict with the MRC staff's,cosition en fire watches.

To avoid c:nfusion and possible c:nflicMng ;uidance, Regulat:ry Position C.2 has been revised so that Subdivision 3.2.3 of ANSI N45.2.3-1973 is not considered part of the guide.

The deficiencies in ANSI Ma5.2.3-1973 identified abcve have been brought to the attention of the respons-ible standard's committee and revisisn to the standard to correct these deficiencies is presently in progress.

Value/: cact The value of this change is that it will elimina:a any c:nfusien or potantial conflict concerning guicance on fire protecti:n and prevention.

There should be no impact, because the NRC's staff position and guidance concerning fire pr0tectica and preventica activities, including -he stationing of fire wc t:hes, is set forth =cre clearly and in much greater detail in other docum nts. -
