. RESTATEMENT OF VIOLATION "Technical Specification 6.8.1.1(b) requires that written procedures shall be established, implemented, and maintained which limit the amount of overtime worked by individuals performing safety-related functions.
Site Specific Procedure (SSP)-1.7, Overtime Restrictions (Regulatory),
Revision 3, is the implementing procedure for overtime controls.
SSP-1.7 states that an employee may work no more than 16 hours1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br /> in any 24-hour
- period, 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> in any, 48-hour period, or 72-hours in any 7-day time period, excluding shift turnover time, without an approved exemption.
Contrary to the above, from March 26 to March 28, 1996, written procedures were not implemented when Customer Group workers performed safety related functions in excess of the SSP-1.7 limitations without approved exemptions.
During diesel generator circuit testing, a test. performer worked approximately 31.hours out of the previous
- 48. hours without an approved exemption.
Additionally, during March 29 to April 18, several additional examples of workers exceeding limits without an approved exemption, were identified.
This is a Severity Level IV violation (Supplement I)."
1.
Reason For The Viol'ation This violation resulted from a personnel error.
The Customer Group (CG) Supervisor failed to adequately communicate the Site Standard Practice (SSP) overtime restrictions to CG workers for ensuring the SSP overtime requirements were not exceeded without an approved exemption.
Specifically, on March 28, 1996., the backshift work crew was scheduled to return to dayshift.
However, this shift change did not allow an adequate rest period and resulted in the backshift work crew, working 31 hours3.587963e-4 days <br />0.00861 hours <br />5.125661e-5 weeks <br />1.17955e-5 months <br /> in a 48-hour period without obtaining an approved exemption.
Additionally, as noted in the violation, this work crew was assigned to work on. safety-related equipment.

Corrective Actions Taken And Results Achieved To prevent recurrence of this event, BFN CG supervision and personnel were. counseled on management expectations concerning, SSP overtime restrictions.
This counseling session heightened the CG personnel's awareness of the SSP requirements, and defined their responsibility for monitoring their overtime individually to ensure that an approved exemption is obtained if the SSP overtime restrictions are to be exceeded.
- Also, TVA CG management reemphasized to the BFN CG supervisor the need for planning, scheduling, and monitoring employee work hours to avoid violations of SSP overtime restrictions and to ensure appropriate overtime exemptions are obtained when necessary.
To assess the extent of the condition described in the
- NOV, TVA performed a self-assessment of plant staff who perform safety-related functions as described in NRC Generic Letter 82-12, "Nuclear Power Plant Staff Working Hours."
TVA's review included Operations, Engineering, Maintenance, and Radcon group's compliance with SSP-1.7.
To date, TVA's assessment has identified additional examples of a failure to follow procedure in the Maintenance group.
TVA has documented this condition in accordance with the.
corrective action program.
3' Corrective Ste s That
[Have Been Or) Will Be Taken To Avoid Further violations TVA is performing a review of other sections for compliance with overtime restrictions.
Where additional examples are identified, appropriate corrective actions will be taken.
4 ~
Date When Full Co liance Will Be Achieved TVA will be in full compliance by September 18,
- 1996, upon the completion of the review and implementation of any corrective actions.
