                              July 31, 1980  

TO ALL OF OPERATING LICENSES TO ALL LICENSEES OF OPERATING PLANTS AND 
APPLICANTS FOR OPER AND HOLDERS OF CONSTRUCTION PERMITS 

SUBJECT: INTERIM CRITERIA FOR SHIFT STAFFING 

This is to provide you with the manning requirements item (1) of our letter 
of May 7, 1980. Pending completion of the long-term development of criteria 
for shift staffing and administrative controls, the NRC staff has developed 
interim criteria for licensees of operating plants and applicants for 
operating licenses. Except for senior reactor operators, described in the 
these interim criteria for shift staffing shall remain as de Standard Review
Plan, Section 13.1.2, NUREG 75/087. Special requirements regarding the 
utilization and qualifications of an on-shift technical advisor to the shift
supervisor were provided in our letter of October 30, 1979. 

We have changed the previous requirements for senior reactor operators and 
now require that there be one licensed senior reactor operator in the 
control room at all times, other than during cold shutdown conditions. This 
will therefore require that there be a minimum of two senior reactor 
operators at each site at all times, other than during cold shutdown 
conditions, to assure the availability of one senior reactor operator in the 
control room without affecting the freedom of the shift supervisor to move 
about the site as needed. The  criteria for reactor and auxiliary operators 
are stated below and the required staffing levels for selected station 
configurations and various plant operating modes are summarized in the 
enclosed table. 

At any time a licensed nuclear unit is being operated in Modes 1-4 for a PWR
(Power Operation, Startup, Hot Standby, or Hot Shutdown respectively) or in 
Modes 1-3 for a BWR (Power Operation, Startup, or Hot Shutdown 
respectively), the minimum shift crew shall include two licensed senior 
reactor operators (SRO), one of whom shall be designated as the shift 
supervisor, two licensed reactor operators (RO) and two unlicensed auxiliary 
operators (AO). For a multi-unit station, depend upon the station 
configuration, shift staffing may be adjusted to allow credit for licensed 
senior reactor operators (SRO) and licensed reactor operators (RO) to serve 
as relief operators on more than one unit; however, these individuals must 
be properly licensed on each such unit. At all other times, for a unit 
loaded with fuel, the minimum shift crew shall include one shift supervisor 
who shall be a licensed senior reactor operator (SRO), one licensed react 
operator (RO) and one unlicensed auxiliary operator. 

Adjunct requirements to the shift staffing criteria stated above are as 
follows: 

a.   A shift supervisor with a senior reactor operator's license, who is 
     also a member of the station supervisory staff, shall be onsite at all 
     times when at least one unit is loaded with fuel.

                                  - 2 -

b.   A licensed senior reactor operator (SRO) shall, at all times, be in the
     control room from which a reactor is being operated. The shift 
     supervisor may from time-to-time act as relief operator for the 
     licensed senior reactor operator assigned to the control room. 

c.   For any station with more than one reactor containing fuel, the number 
     of licensed senior reactor operators onsite shall, at all times, be at 
     least one more than the number of control rooms from which the reactors
     are being operated. 

d.   In addition to the licensed senior reactor operators specified in a., 
     b., and c. above, for each reactor containing fuel, a licensed reactor 
     operator (RO) shall be in the control room at all times. 

e.   In addition to the operators specified in a., b., c., and d. above, for
     each control room from which a reactor is being operated, an additional
     licensed reactor operator (RO) shall be onsite at all times and 
     available to serve as relief operator for that control room. As noted 
     above, this individual may serve as relief operator for each unit being
     operated from that control room, provided he holds a current license 
     for each unit. 

     Auxiliary (non-licensed) operators shall be properly qualified to 
     support the unit to which assigned. 

g.   In addition to the staffing requirements stated above, shift crew 
     assignments during periods of core alterations shall include a licensed
     senior reactor operator (SRO) to directly supervise the core 
     alterations. This licensed senior reactor operator may have fuel 
     handling duties but shall not have other concurrent operational duties.

These criteria do not relieve licensees of any special requirements for 
additional operators which may have been imposed for individual units. 

General application of revised shift staffing criteria will be the subject 
of a rulemaking proceeding. However, these interim criteria will be 
effective for plants receiving operating licenses during the interim period 
(including TMI-1). Licensees of plants already holding operating licenses 
shall examine their current staffing practices and capabilities in light of 
these interim criteria and advise this office within 90 days of receipt of 
this letter of the date by which their shift staffing could be in compliance 
with these criteria. Licensees of operating plants shall take steps to meet 
the revised criteria as soon as practical, but no later than July 1, 1982. 
In your response to this letter, you are requested to discuss your plans, 
schedules and commitments to meet these staffing criteria. Holders of 
construction permits who have not as yet applied for an operating license 
should factor these criteria into their recruitment and crew training plans.

                                  - 3 -

In addition, licensees of operating plants and applicants for operating 
licenses shall include in their administrative procedures (required by 
license conditions) provisions governing required shift staffing and 
movement of key individuals about the plant. These provisions are required 
to assure that qualified plant personnel to man the operational shifts are 
readily available in the event of an abnormal or emergency situation. 

The administrative procedures shall also set forth a policy concerning over-
time work for the senior reactor operators, reactor operators, and shift 
technical advisor required by these interim criteria. These procedures shall
stipulate that overtime shall not be routinely scheduled to compensate for 
an inadequate number of personnel to meet the shift crew staffing 
requirements. In the event that overtime must be used, due to unanticipated 
or unavoidable circumstances, the following overtime restrictions shall be 
followed: 

(1)  An individual shall not be permitted to work more than 12 hours 
     straight (not including shift turnover time).  

(2)  An individual shall not be permitted to work more than 24 hours in any 
     48 hour period. 

(3)  An individual shall not work more than 72 hours in any 7 day period. 

(4)  An individual shall not work more than 14 consecutive days without 
     having two consecutive days off. 

However, recognizing that circumstances may arise requiring deviation from 
the above restrictions, such deviation may be authorized by the plant 
manager or higher levels of management in accordance with published 
procedures and with appropriate documentation of the cause. 

The limitations on overtime follow the guidance provided in IE Circular 
80-02, except for the requirement noted above on the restriction on use of 
overtime in circumstances that are unavoidable. 

Operating license applicants shall complete these administrative procedures 
before fuel loading. Development and implementation of the administrative 
procedures at operating plants will be reviewed by the Office of Inspection 
and Enforcement beginning 90 days after the date of this letter. 

                                   Sincerely, 


                                   Darrell G. Eisenhut, Director 
                                   Division of Licensing
