NUCLEAR REGULATORY COMMISSION

[NRC-2022-0036]


Water Sources for Long-Term Recirculation Cooling Following a 
Loss-of-Coolant Accident

AGENCY: Nuclear Regulatory Commission.

ACTION: Draft regulatory guide; extension of comment period.

-----------------------------------------------------------------------

SUMMARY: On February 8, 2022, the U.S. Nuclear Regulatory Commission 
(NRC) solicited comments on draft regulatory guide (DG), DG-1385, 
``Water Sources for Long-Term Cooling Following a Loss-of-Coolant 
Accident.'' The public comment period was originally scheduled to close 
on March 10, 2022. The NRC has decided to extend the public comment 
period to allow more time for members of the public to develop and 
submit their comments.

DATES: The due date for comments requested in the document published on 
February 8, 2022 (87 FR 7209) has been extended. Comments should be 
filed no later than April 8, 2022. Comments received after this date 
will be considered, if it is practical to do so, but the Commission is 
able to ensure consideration only for comments received on or before 
this date.

II. Discussion

    On February 8, 2022, the NRC published a document in the Federal 
Register (87 FR 7209) soliciting comments on DG-1385, ``Water Sources 
for Long-Term Cooling Following a Loss-of-Coolant Accident.'' This DG 
is proposed Revision 5 to Regulatory Guide 1.82, which describes an 
approach that may be used to determine quality standards acceptable to 
the NRC staff, to meet the regulatory requirements for sumps and 
suppression pools that provide water sources for emergency core 
cooling, containment heat removal, or containment atmosphere cleanup 
systems. It also provides guidelines for evaluating the adequacy and 
the availability of the sump or suppression pool for long-term 
recirculation cooling following a loss-of-coolant-accident, and the use 
of containment accident pressure in determining the net positive 
suction head for the emergency core cooling and containment heat 
removal pumps. This proposed revision guidance applies to both the 
pressurized-water reactor and boiling-water reactor types of light-
water reactors. The comment period was originally scheduled to close on 
March 10, 2022. Upon the request of the Nuclear Energy Institute, the 
NRC has decided to extend the public comment period on this document 
until April 8, 2022, to allow more time for members of the public to 
submit their comments.

    Dated: March 2, 2022.
