Information Notice No. 80-06
NOTIFICATION OF SIGNIFiCANT EVENTS
Description of Circumstances:
On February 29, 1980, an immediately effective amendment to the Nuclear
Regulatory Commission (NRC) regulations is to be published in the Federal
Register that sets forth requirements for the reporting of significant
events at operating reactors. A copy of the NRC Notice of Rulemaking is
enclosed. The reporting requirement in the new section 50.72, "Notification
of significant events," to 10 CFR Part 50 will be effective immediately
under the authority of GAO clearance R0072 (Emergency Generic Clearance
-Expires 7/31/80), and is being submitted to the General Accounting Office
for review under the Federal Reports Act for permanent approval under NRC's
existing GAO clearance for 10 CFR Part 50 (#R0071).
Paragraph (a) of SS 50.72 requires, in part, that the licensee notify the
NRC Operations Center as soon as possible and in all cases within one hour
by telephone of the occurrence of any significant event listed in the
paragraph. Reports of events pursuant to SS 50.72 that are similarly
required by Technical Specifications to be reported by telephone within 24
hours are considered to satisfy the Technical Specification requirement for
prompt telephone notification. Technical Specification requirements for
confirmation reports by telegraph, mailgram, or facsimile transmission still
The primary channel for telephone notification of significant events should
be through the dedicated telephone line established between the licensee and
the NRC Operations Center. An NRC Duty Officer is available, 24 hours a day,
in the NRC Operations Center. In case the licensee is unable to report a
significant event over the dedicated telephone line, the licensee should
contact the NRC Operations Center directly by commercial line.
Notice of Rulemaking
U.S. NUCLEAR REGULATORY COMMISSION
10 CFR Parts 20 and 50
Immediate Reporting of Significant
Events at Operating Nuclear Power Reactors
AGENCY: U. S. Nuclear Regulatory Commission
ACTION: Final Rule
SUMMARY: The Nuclear Regulator Commission (NRC) is amending its
regulations, effective immediately, to require timely and accurate
information from licensees to NRC following significant events at operating
nuclear power reactors.
EFFECTIVE DATE: February 29, 1980
FOR FURTHER INFORMATION CONTACT: Dudley Thompson, Office of Inspection and
Enforcement, U. S. Nuclear Regulatory Commission, Washington, D.C. 20555,
SUPPLEMENTARY INFORMATION: The capability of the NRC to make timely
decisions and to provide adequate assurance regarding actual or potential
threats to public health and safety, depends heavily on the rapidity with
which significant events are communicated by nuclear power reactor licensees
to NRC. The majority of events occurring throughout the nuclear industry
pose little or no serious or immediate threats to the public health and
safety: however, certain events do pose such threats or generate fear of
NRC has an important obligation to collect facts quickly and accurately
about significant events, assess the facts, take necessary action, and
inform the public about the extent of the threat, if any, to public health
and safety. Not only must NRC act promptly to prevent or minimize possible
injury to the public, it must also take appropriate action to alleviate fear
or concern created as a result of such events.
After the accident at Three Mile Island on March 28, 1979, the NRC staff
acted to ensure the timely and accurate flow of information from licensees
of operating nuclear power reactors following significant events. Dedicated
telephone lines have been installed from all operating power plants to the
NRC Operations Center and the Regional Offices. Aline is located in each
control room with provisions made for extensions to be located at other
specified locations at the facility. When these phones are picked up to
report significant events, they automatically ring at the NRC Operations
Center and can be held open as long as needed.
NRC's Office of Inspection and Enforcement (OIE) issued Bulletins and sent
letters requesting each licensee to review its prompt reporting procedures
to NRC. These were intended to make certain that each licensee notifies NRC
within one hour of the time the reactor is not in a controlled or expected
condition of operation. Once the licensee has notified NRC, an open,
continuous communication channel is established and maintained between the
licensee and NRC.

The NRC staff has continued to evaluate licensees' responses to OIE's
Bulletins and letters and to analyze the kinds of significant events that
should be reported immediately. By their very nature, OIE's Bulletins and
letters did not impose requirements on licensees, and in several instances
licensees have not immediately reported significant events to NRC. Moreover,
the Bulletins and letters did not describe in sufficient detail the specific
types of significant events NRC determined had to be reported immediately.
The Commission has found that in order to take necessary action to protect
the health and safety of the public, twelve types of significant events
should be reported immediately (within one hour) to it. Consequently, NRC
has decided to publish a rule requiring the immediate reporting by telephone
of these events that could result in an impact on the public health and
safety such as those leading to initiation of the licensee's emergency plan
or any section of the plan, the causing of the nuclear power plant to be in
an uncontrolled condition, the exceeding of a safety limit, an act of
sabotage, or an uncontrolled release of radioactivity. With regard to
initiation of the licensee's emergency plan, the Commission is presently in
the process of promulgating a rule concerning requirements for emergency
plans for nuclear power plants in NUREG-0610. This guidance has been sent to
all affected licensees.
In view of (1) the significance of these twelve types of event with respect
to their ability to jeopardize the health and safety of the public, (2) the
fact that most of these event are not required presently to be reported
immediately to NRC, (3) the problem of licensees not having reported such
events to NRC after receipt of OIE's Bulletins and letters, and (4) NRC's
immediate need to know in order to act quickly, NRC has determined that
there is good cause to waive the opportunity for the public to comment on
this rule before its effective date, and has determined, therefore, that it
is in the public to interest to make this rule effective immediately.
Although this rule is being published ineffective form without a prior
public comment period, the public is invited to submit its views and
comments. If possible, these comments should be submitted by April 29, 1980.
After reviewing any views and comments submitted, the Commission may
reconsider or modify the rule as it deems necessary.
Pursuant to the Atomic Energy Act of 1954, as amended, the Energy
Reorganization Act of 1974,as amended, and sections 552 and 553 of title 5
of the United States Code, the following amendments to 10 CFR Part 20 and 10
