identified:

Technical Specification 7.3.4, Normal Power Operation, states that the principal functions of operators during power operation includes "the adjustment of the control rod pattern to accommodate changes in reactivity and to maintain the desired power distribution" and "the evaluation of abnormal conditions and the initiation of corrective action as required".

Technical Specification 5.2.2.f, Abnormal Behavior of the Control Rod System, requires "an immediate and thorough investigation shall be made of the occurrence of any abnormal behavior. . . of the control system to determine the cause and safety significance of the occurrence".

Consideration may be given to extending your response time for good cause shown.
