UNITED STATES
NUCLEAR REGUALTORY COMMISSION
WASHINGTON, D.C. 20555
February 18, 1981
TO ALL LICENSEES OF OPERATING PLANTS AND HOLDERS OF CONSTRUCTION PERMITS
SUBJECT: POST-TMI Requirements FOR THE EMERGENCY OPERATIONS FACILITY
(GENERIC LETTER 81-10)
Gentelmen:
On October 31, 1980, the NRC staff sent you a clarification letter (NUREG-
0737) regarding approved TMI Action Plan items which deferred clarification
of item III.A.1.2, upgrade Emergency Support Facilities. The Commission has
now finalized it's position with respect to location and habitability
requiremtns for the Emergency Operations Facility and staffing levels for
emergency situations. Clarification on these issues is enclosed. In the near
future, we expect to issue further guidance for emergency response
facilities in connection with finalization of NUREG-0696. Implementation
schedules for related items affected by the issuance of NUREG-0696 will be
set forth at that time.
It is expected that the requirements contained herin will be met.
Accordingly, you are requested to furnish, within forty-five (45) days of
this letter, confirmation that the implementation dates indicated in
Enclosure 1 will be met. For any date that cannot be met, furnish a proposed
revised date, and justification for the delay.
This request for information was approved by GAO under a blanket clearance
number R0072 which expires November 30, 1983. Comments on burden and
duplication may be directed to the U. S. General Accounting Office,
Regulatory Reports Review, Room 5106, 441 G Street, N. W., Washington,D.C.
20548.
Sincerely,

III.A.1.2 UPGRADE EMERGENCY SUPPORT FACILITIES
Position
Each operating nuclear plant shall maintain an onsite technical support
center (TSC) separate from and in close proximity to the control room that
has the capability to display and transmit plant status to those individuals
who are knowledgeable of and responsibile for engineering and management
support of reactor operations in the event of an accident. The center shall
be habitable to the same degree as the control room for postulated accident
conditions. The licensee shall revise his emergency plans as encessary to
incorporate the role and location of the TSC. Records that pertain to the
as-bulit conditions and layout of structures, systems, and components shall
be readily available to personnel in the TSC.
An operational support center (OSC) shall be established separate from the
control room and other energency response facilities as a place where
operations support personnel can assemble and report in an emergency
situation to receive instructions from the operating staff. Communications
shall be provided between the OSC, TSC, EOF, and control room.
An emergency operations facility (EOF) will be operated by the licensee for
continued evaluation and corrdination of all licensee activities related to
an emergency having or potentially having environmental consequences.
Changes to Previous Requirements and Guidance
(1) NUREG-0696, "Functional Criteria for Emergency Response Facilities," to
be issued shortly,will provide more detailed design and functional
criteria.
(2) Table III.A.1.2-1 (Table B-1 to NUREG-0654, Revision 1), establishes
staffing levels for emergency situations. The revision of NUREG-0654
establishes staging of staffing for 30 to 60 minutes rather than
requiring capability for required augmentation at 30 minutes. The
implementation schedule for licensed operators and STA on shift shall
be as specified in Task Action Item I.A.1.3. Any deficiencies must be
fully removed by July 1, 1982.
(3) Implementation schedule has been changed.
(4) Establishes a requirment to submit emergency response facilities (ERFs)
conceptual design information by June 1, 1981.
(5) Establishes guidance on ROF location and habitability
III.A.1.2-1 3-186a
.
Clarification
NUREG-0696 was issued in draft for comment. The staff has analyzed the
comments, prepared the final version for Commission review, and will issue
the final version of NUREG-0696 in the near future.
NUREG-0696, "Functional Criteria for Emergency Response Facilities," will
porvide more detail design and functional criteria than previously
prescribed. The operational date for the final emergency response facilities
has been changed to October 1, 1982. The interim TSC and EOF completed by
January 1, 1980 shall continue to be operated until the upgraded facilities
become fully operational.
An emergency operations facility (EOF) will be operated by the licensee for
continued evaluation and coordination of all licensee activities related to
an emergency having or potentially haveing environmental consequences. The
criteria regarding the location and habitability of the EOF is given in
Table III.A.1.2-2.
Applicability
This requirement applies to all operating reactors and applicants for
operating license.
Inplementation
For operating reactors, the upgraded emergency response facilities
conceptual design shall be submitted by June 1, 1981. For operating license
applications, such design information should be provided in connection with
the OL review process. The upgraded facilities shall be operational by
October 1, 1982, for all facilities licensed for operation prior to that
date. For OL expected to be issued after October 1, 1982, the upgraded
facilities shall be operational prior to receiving an operating license.
Type of Review
A pre-implementation review of the conceptual design submittals will be
performed. A post-implementation review will be performed for the October 1,
1982 requirement.
Documentation Required
Facility conceptual design description shall be provided by June 1, 1981
including:
(1) Task functions of the individuals required to report to the TSC and EOF
upon activation and for each emergency class; and
(2) Descriptions of TSC instrumentation, instrument quality, instrument
accuracy and reliability.
(3) Descriptions of TSC power supply systems, power supply quality,
reliability and availability, and consequences of power supply
interruption.
(4) Descriptions of the design of the TSC data display systems, plant
records and data available and record management systems.
(5) Descriptions of the data transmission system to be installed between
the TSC and control room.
(6) Description of data to be provided to the EOF.
