UNITED STATES ATOMIC ENERGY COMMISSION WAIVER TO TECHNICAL SPECIFICATIONS LICENSE DPR-38 DOCKET NO. 60-7ZDJ OCONEE NUCLEAR STATION, UNIT 2 j
0 Introduction On November 22, 1973, Ken Canady of Duke Power Company contacted A. Schwencer j
LWR 2-3, by phone and requested that Technical Specification 3.5.2.5-e,
" Control Rod Positions," be waived temporarily (for about 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />)
]
during the Christmas holidays on Oconee, Unit 2 in order to permit calibration of x-core detectors in the range of power axial imbalance outside the administratively controlled limits established for LOCA
)
peak Kw/ft considerations.
Schwencer contacted Peltier, LWR 2-3, and Peltier reviewed the matter j
by phone with Duke (Canady) and informed the RO Duty Officer (Henderson) of the decision to grant the waiver.
Since the appropriate AD was not available, Schwencer authorized the waiver.
Evaluation Due to an oversight in the preparation of the Technical Specification 3.5.2.5-e, latitude was not provided to exceed the administrative 1y controlled power axici imbalance limits for the purpose of calibrating
)
. the x-core detectors and performing other physics tests during the power ascension program.
Since the x-core detectors are used for administrative control of the l
axial imbalance, it is necessary that they be calibrated in the range of the administrative limits.
l This Technical Specification is currently under review by Licensing and will contain such a provision in the future.
i The reactor is protected by the reactor power imbalance trip envelop provided in Technical Specification 2.1, " Safety Limits, Reactor Core".
Therefore, health and safety of the public was not endangered by this te=porary waiver.

w JAN y yy4 Conclusion e On. November: 22,' 1973, Duke. Power Company. (Canady) *.as granted a ' waiver to Technical, Specification 3.5.2.5-e by phone in accordance with the.
following understanding:
For Unit 2, the imbalance limits in' Technical Specification 3.5.2.5-e _
i Figure 3.5.2-3;. may be exceeded at 75% power for the purpose of. completing physics' tests required to calibrate'x-core detectors.
Quadrant tilt will be' held to 4% or.less while the imbalance limit is exceeded.
The.x-core detectors were to be calibrated during *he Christmas holidays'and the calibration was to require about 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.-
