February 1, 1980 IE Circular No. 80-02 NUCLEAR P0'.-lER PLANT STAFF MORK H0fJRS Description of Circunstances:
Studies indicate that with fatigue, especially because of loss of sleep, an individual's detection of visual signals deteriorates markedly, the tine it takes for a person to make a decision increases and more errors are made, and reading rates decrease.
Other studies show that fatigue results in personnel ignoring some signals because they develop their own subjective standards as to what is important, and as they become more fatiqued they ignore more signals.
Inspections of personnel perfornance and training since the accident at Three Mile Island, have shown that in certain situations facility personnel are either reouired or allowed to remain on duty for extended periods of time.
Also, complaints have been received fron some licensed nuclear power plant operators concerning the number of continuous hours they have been on duty.
Licensee nanagenent is responsible for providing a sufficient number of trained personnel who are in the proper physical condition to operate and maintain the plant. Licensee management should review their administrative procedures covering the working hours of nuclear nower plant staff. These procedures should establish a sound policy covering workina hours for plant staff who perform safety related functions (e.g., senior reactor operators, reactor operators, health physicists, auxiliary operators, I&C technicians, key maintenance personnel, etc.)
Subcommittee ANS-3 is currently developing criteria to address the subject of operator work hours. These guidelines will becone a part of ANSI N18.7. The NRC is also considering issuing requirements for administrative procedures that would control staff overtime.
Until either the ANSI Standard is issued and endorsed by NRC (via a Reculatory Guide) or separate requirements are issued by NRC, it is recomnended that the following guidance 'e used. The c
guidance should be aoplied to all personnel performing a safety related function:
1.
Scheduled work should be linited to the following naxinum work hours:
a.
An individual should not be oermitted to work more than 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> straight.
IE Circular ?!n. 80-02 February 1, 1980 Page 2 of 2 b.
There should be at least a 12-hour break between all v>ork periods.
c.
An individual should not work nore than 72-hours in any 7-day period.
d.
An individual should not work nore than 14 consecutive days without having 2 consecutive days off.
2.
In the event that soecial circunstances arise that require deviation from the above, such deviatSns should be authorized by the Station tianager with approoriate documentation of the cause.
Plants should be staffed and schedules developed to operate such that exceptions are not required.
3.
If an operator is required to work in excess of 12 continuous hours, his duties should be carefully selected.
It is preferable that he not be assioned any task that affects core reactivity or could possibly endanger the safe operation of the plant, flo written resoonse to this Circular is required.
If you desire additional infornation reqarding this natter, contact the Director of the aopropriate flRC Regional Office.
