20555 July 29, 1980 IE Information Notice No. 80-06 Supplement Page 1 of 2 NOTIFICATION OF SIGNIFICANT EVENTS AT OPERATING POWER REACTOR FACILITIES 4

Description of Circumstances:

IE Information Notice No. 80-06 (Iil 80-06) issued on February 27, 1980, forwarded a Federal Register Notice which indicated that the NRC regulations were amended j

by adding a new 6 50.72, " Notification of significant events", to 10 CFR Part i

50. The effective date of the new rule was February 29, 1980.

This Information Notice supplements IN 80-06 and provides clarification on types of events that are required to be reported in accordance with the rule.

Public comments on the rule indicate the need for more detailed clarification on what occurrences are reportable in regard to certain event types listed in the rule.

Commenters particularly stressed the need to establish more defini-tive thresholds for notifications of certain types of events.

Experience so far with notifications being made in accordance with 6 50.72 also suggest the need for clarification and more definitive guidance.

The general categoriza-tion of some of the event. types listed in the rule has resulted in notifica-tions of events of less significance than was originally intended.

As stated in the Federal Register Notice implementing 5 50.72, the rule was intended to require immediate notification of " serious events that could result in an impact on the public health and safety."

The notification requirements in f 50.72 are currently being evaluated to

~

determine actions needed in light of public comments on and experience with the rule.

Notwithstanding future actions which may include some modifications to the rule and supplementary regulatory guidance, a short term need exists for clarifying the thresholds for notifications of certain categories of events.

The following paragraphs provide clarification on what is reportable pursuant to the event categories listed in items (1), (7) and (9) of the rule.

Item (1) of S 50.72(a) requires notification of: "A y event requiring initiation n

of the licensee's emergency plan or any section of that plan." Notifications under this item refer to those initiating events or conditions that place the facility in a " Notification of Unusual "
