By a telephone call on October 21, 1993, at 1:00 p.m., you informed the NRC that Surry Unit 1 would not be in compliance with TS 3.12.C.3 which requires the plant to be in Hot Shutdown by 5:44 p.m. on October 21, 1993.
You provided as justification for continued operation that the affected Control Bank D control rod assemblies which were immovable on demand from the Control Rod Drive System were aligned, above the insertion limits, and trippable. In addition, the faulted* condition did not affect the ability of the control rod assemblies to perform their intended safety function when a safety system setting is reached. As a compensatory action, you indicated that the power level will be maintained stable during the troubleshooting and repair activities.
Based on our review of your justification, including the compensatory measure identified above, we have concluded that this course of action involves minimum or no safety impact, and we are cl early satisfied that this exercise of enforcement discretion is warranted from a public health and safety perspective.
Therefore, we wil 1 not enforce compliance with TS 3.12. C. 3 for the period 9:44 a.m. on October 21, 1993, to 9:44 a.m. on October 24, 1993. This discretion was granted verbally by a telephone call from M.
