SUBJECT:
INTERPRETATIONOFPARAGRAPH50.72(b)(1)(v) of 10 CFR PART 50 (F03007984) k'ith the implenentation of the irrediate notification requirenents in 10 CFR 50.72, the regulation was modified to allow the NRC to eliminate the Unusual Event Classification. However, for events,of significance currently classifed by most licensees as Unusual Events, a new section((50.72(b)(1)) was added to the regulations.
Paragraph 50.72(b)(1)(v) of this re section states as followes:
Any event that results in a major loss of emergency assessment capability, offsite response capability, or communications capability (e.c., significant portion of control room indications, Emergency Notification System, or offsite rotification system).
In regards to this section, our office has received several telephone requests from licensees and the enclosed nenorande. from the Kewaunee Senior Resident inspector reouesting clarification of this paragraph under the followino general headings:
1.
kt.at does the tem " major loss" mean, especially as it related to the offsite notification system?
2.
Does the loss of response capability apply only to licenset personnel?
3.
What is considered a " major loss
- of offsite response capability and how does a licensee or inspector detemine that such a loss has or had occurred?
4.
What does the tenn "significant portion" of control roon indications mean?
5.
At what point does adverse weather (e.g. severe snowfall or ice stom) indicate a major loss of response. capability for licensee personnel?
We feel that headquarters guidance delineating the meaning of thes*e tems is needed, and should probably take the form of an Infomation Notice due to its generic frp11 cations.

In the interim, we have told licensees that further outdance is pending; however, we would interpret the answers to the above mentioned questions as follows:
1.
A " major less" means either creater than 50! of the paraneter indication, sirens, radios, dedicated corrnunication link, etc.: or the inability to
_ notify creater than 50% of the public in the EPZ due to pronpt notification j
system failure or inoperability.
1 2.
The loss of response capability applies only to the licensee, since the Statement of Considerations related to this paragraph begins by statino
"... covers those events that would impair a licacsee's ability to deal with an accident or emergency."
3.
A major loss of offsite response capability would mean the loss of greater j
t'han 50% of the ability of an Energency Response Facility to function, e.g.,
loss of dese assessment capability, corrunication links, ability to activate an ERF, etc.
4.
Significant portion of control room indications reans the inability to deter-r.ine any one particular EAL due to loss of instraentation needed to assess that EAL.
5.
For adverse weather conditions such as heavy sn:wfall or ice stonns to cause e major less of response capability for licensee personnel the weather con-dition would have to be of sufficient F.agnitude to prevent activation of an Eneroency Response Facility by any means: e.o., all Energency Directors listed waald be unable to reach the TSC or EOF, etc.
If our internreation is inconsistent with final cuidance, we would like an early resnonse infon-ino us of the appropriate final nuidance which we will then orovide tc licensees askina for interpretation of this caracraoh.
