Figure 13.5-1 shows the organizational structure of these various procedures.
It is the appropriate responsible manager's responsibility to ensure that required reviews and approvals are completed before authorizing the use of any site procedure.
In addition to planned changes in the plant and its procedures, accidental or gradual changes in plant equipment, characteristics, or conditions can occur. Each supervisor and employee has the responsibility to be continually alert for such changes and to initiate procedure changes which may then be required. The periodic inspection of plant equipment and the continuing review and analysis of operating data from plant logs, instruments, and tests provide regular sources of information on plant conditions.
Temporary instructions are generated when conditions exist such that normal operation or normal administrative control cannot be followed. They are canceled or assigned expiration dates based on when the situation is returned to normal and are periodically reviewed. The administrative procedure system prescribes the methods whereby site procedures can be temporarily changed without delay when the need arises. Temporarily approved changes to procedures may be made provided:
(a) The intent of the existing procedure is not altered; (b) The change is approved by two members of the plant management staff, at least one of whom holds a Senior Reactor Operator license on the unit affected; and SITE PROCEDURES 13.5-1
WATTS BAR WBNP-112 (c) The change is documented and reviewed by PORC and approved by the Plant Manager or his designee in accordance with approved administrative procedures within 14 days of implementation.
13.5.1.3 Administrative Procedures Administrative procedures address basic programs and organizational interfaces.
They are used to define the authority and responsibility of the reactor operators and senior reactor operators for the general conduct of operation and the programs necessary to support activities affecting safety.
The administrative procedures that prescribe the general conduct of operation satisfy the requirements of 10 CFR 50.54(i-m) and ensure the proper manipulation of controls by licensed reactor operators or senior reactor operators. These procedures also provide for assignment of the duties and responsibilities of shift personnel, shift relief and turnover, limitations on working hours, independent verification of the correct performance of operating activities, feedback of operating experience, plant housekeeping, communications techniques, and control room access. Figure 13.5-2 provides the layout of control boards within the Main Control Room to which access is controlled, and it shows typical operator surveillance areas.

13.7.2 Personnel and Program Evaluation TVA's Nuclear Power organization is responsible for protection of power properties with functional responsibility delegated as shown in the Nuclear Power Organization Description.[7]
The Watts Bar Security Program is evaluated by individual(s) who are knowledgeable of security requirements and independent of both security management and supervision. The review is conducted to determine the effectiveness of security procedures and personnel practices as they relate to the implementation of licensed security documents. Based on the review, a detailed report is submitted to appropriate management recommending corrective action and improvements, if any, to ensure the successful implementation of the security program[8].
13.7.3 Physical Security of TPBARs Watts Bar Nuclear Plant Unit 1 has been approved by the Nuclear Regulatory Commission (NRC) for tritium production. Physical Security for tritium production is identified within a Department of Energy (DOE) approved security plan for WBN that is a separate plan from the NRC Physical Security Plan required by 10 CFR 50. DOE will continue to be the cognizant security agency for physical security concerning protection of the tritium producing burnable absorber rod (TPBARs). NRCs security oversight and responsibilities will remain the same.
