INSPECTION PROCEDURE 71715

SUSTAINED CONTROL ROOM AND PLANT OBSERVATION

PROGRAM APPLICABILITY: 2515

71715-01 INSPECTION OBJECTIVES 01.01 To provide an opportunity for the resident inspector, an offsite inspector or regional management to evaluate a licensee* s control room and plant performance over a sustained period. The resident inspector should gain new insight from the sustained control room observation and the offsite inspector's independent view (if an offsite inspector is used).

01.02 This procedure has been established to permit long-term, continuous observation of control room activities. More than one inspector is generally required for this type of sustained observation. However, due to varying circumstances, it may be more appropriate for regional management to assign more inspectors is inapplicable. the task to a single inspector, in which case the direction regarding two or

with control room protocol regarding access and administrative controls prior Inspectors who are not part of the site resident staff should become familiar to the initiation of the inspection.

02.02 Ins~ection Items. For a period of time determined to be appropriate by regiona management, observe operational activities conducted by the detracts from their ability to monitor and operate the plant. The inspector licensee. The inspector should obtain the licensed operators* views on what should evaluate the following conditions or practices as appropriate.

a. Operators are attentive and responsive to plant parameters and condi-l tions. Operators are aware of the reasons for annunciators that are in the alarm condition

b. Plant evolutions and testing are planned and properly authorized. When a more complex special evolution or non-routine evolution takes place, a pre-evolution briefing of the shift crew and other personnel affected by the evolution may be appropriate.

c. Procedures are used and followed as required by plant policy.

d. Equipment status changes are appropriately documented and communicated to appropriate shift personnel, when they occur.

e. The operating conditions of plant equipment are effectively monitored, and appropriate corrective action is initiated when required.

f. Backup instrumentation, measurements, and readings are used as appropriate when normal instrumentation is found to be defective or out of tolerance. Equipment out of service controls are adequate.

g. Logkeeping is timely, accurate, and adequately reflects plant activities and status.

h. Operators follow good operating practices and maintain shift professionalism in conducting plant operations. Operators are aware of ongoing plant activities and surveillance testing. Administrative controls are adequate to ensure in-plant work activities are being performed with the knowledge of control room personnel.

i. The control room environment is adequate for conduct of duties; i.e. lighting, noise levels, traffic volume, number of alarms, ventilation, heating and cooling are acceptable.

j. Communication between workers and first line supervisors, as well as specific communications procedures. interdepartmental communications, are appropriate and follow any plant *

k. Shift turnovers are professional and provide the oncoming shift an adequate update from the last time they were on shift.

1. Blocking/tagging and valve lineups are conducted in accordance with plant procedures and are adequate to provide isolation or proper system lineup for existing plant conditions.

m. The administrative burden on the control room supervisor does not prevent adequate supervision of shift activities.

n. Manipulation of plant controls that may effect reactivity changes is performed by licensed operators, or by individuals enrolled in an approved operator licensing training program who are under the direction and in the presence of a license operator.

o. Overall material condition of the plant does not hinder the effectiveness of the operators in conducting normal plant evolutions as well as non-routine evolutions.

p. Technical satisfied. Specification limiting conditions for operation are Entry into LCO action statements are controlled and tracked. Additional surveillance activities required by action statements are performed and tracked.

q. Abnormal conditions and equipment problems are evaluated promptly to determine the impact on plant safety, equipment operability, and reportability. Plant management is informed of abnormal conditions as required by plant policies.

71715-03 INSPECTION GUIDANCE General Guidance This procedure is intended to be used when regional management determines that as a result of plant events or poor licensee performance it is necessary to conduct a continuous surveillance of licensee performance. This procedure was developed based on the assumption that the inspection would continue for approximately 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />; however, other factors may indicate that a shorter or longer surveillance period is required. Regional management can use this procedure to allow one resident to participate in the inspection of another Management participation in the implementation of this procedure is left to facility thereby enhancing the inspection techniques of both residents.

the discretion of regional management.

Specific Guidance 03.01 Inspection Requirements 02.01. If the inspection period is of short duration, both inspectors should be present during the period. If the period is greater than four hours, the inspectors should divide the observation period so that at least one inspector is observing plant activities during the entire period.

03.02 Inspection Requirement 02.02. The criteria listed in this section provides only broad guidance for evaluating operational activities. The inspectors should pay particular attention to the performance of licensed and non-licensed (auxiliary) operators. Approximately 25 percent of the obser vati9n time should be spent observing ~perator performance outside the control room. Backshift observations should be included as feasible, de pending on the duration of the inspection. The regions should modify these criteria as necessary.

03.02.a No inspection guidance.

03.02.b Inspection Requirement 02.02b. When evaluating complex or non routine evolutions, the inspector may consider the following supporting activities:

Effectiveness of written communications, such as daily orders or special orders, in directing plant operations.

Adequacy of management involvement during the evolution.

Appropriateness of any risk assessment to understand the risk associated with the activity.

03.02.c-q No inspection guidance
