February 1, 1980 IE Circular No. 80-02 NUCLEAR POWER PLANT STAFF MORK HOURS Description of Circunstances:
Studies indicate that with fatigue, especially because of loss of sleep, an individual's detection of visual signals deteriorates market 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 fatigued they ignore more signals.
Inspections of personnel performance and training since the accident at Three Mile Island, have shown that in certain situations facility oersonnel are either reauired or allowed to remain on duty for extended periods of time.
Also, corolaints have been received from some licensed nuclear power plant operators concerning the number of continuous hours they have been on duty.
Licensee nanagerent is responsible for providing a sufficient number ~of trained personnel who are in the proper physical condition to operate and maintain the plant. Licensee ranagement should review their administrative orocedures covering the working hours of nuclear nower plant staff. These procedures should establish a sound policy covering workinq 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.)
Subconmittee ANS-3 is currently developing criteria to address the subject of operator work hours. These guidelines will become a cart of ANSI N18.7. The NRC is also considering issuing requirements for administrative Drocedures that would control staff overtine.
Until either the ANSI Standard is issued and endorsed by NRC (via a Reculatory Guide) or separate requirements are issued by NRC, it is recommended that the following guidance be used.
The guidance should be aoplied to all personnel performing a safety related function:
1.
Scheduled work should be linited to the following naxinum work hours:
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 /> a.
straight.
IE Circular No. 83-02 February 1, 1980 Page 2 of 2 b.
There should be at least a 12-hour break bet'seen all work 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 circurstances arise that require deviation from the above, such deviations should be authorized by the Station Manager with appropriate documentation of the cause.
Plants should be staffed and schedules developed to operate such that exceptions are not reauired.
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.
No written resoonse to this Circular is required.
If you desire additional infornation regarding this natter, contact the Director of the appropriate NRC Regional Office.
