20555 February 1,1980 IE Circular No. 80-02 NUCLEAR POWER PLANT STAFF WORK HOURS Description of Circumstances:
Studies indicate that with fatigue, especially because of loss of sleep, an (No,idual's detection of visual signals deteriorates markedly, the time it t e es for a person to make a decision increases and more errors are made, and reading retes 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 g,ersonnel performance and training since the accident at Three Mile Island, have shown that in certain situations facility personnel are either required or allowed to remain on duty for extended periods of time.
Also, complaints have been received from some licensed nuclear power plant operators concerning the number of continuous hours they have been on duty.
Licensee management 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 power plant staff.
These procedures should establish a sound policy coverin
. staff who perform safety related functions (e.g., g working hours for plant 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 become 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 Regulatory Guide) or separate requirements are issued by HRC, it is recommended that the following guidance be used.
The guidance should be applied to all personnel performing a safety related function:
1.
Scheduled work should be limited to the following maximum work hours:
An individual should not be permitted 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.
Sb YS IE Circular No. 80-02 February 1, 1980 Page 2 of 2 G
There should be at least a 12-hour break between all work periods.
s.
An individual should not work more than 72-hours in any 7-day period.
c.
d.
An individual should not work more than 14 consecutive days without having 2 consecutive days off.
2.
In the event that special circumstances 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 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 assigned any task that affects core reactivity or could possibly endanger the safe operation of the plant.
No written response to this Circular is required.
If you desire additional information regarding this matter, contact the Director of the appropriate NRC Regional Office.
