WBN Incore Instrument Room Air 2-PTI-031B-01 Unit 2 Conditioning System Rev. 0000 Page 10 of 128 3.0 PRECAUTIONS AND LIMITATIONS A. Standard precautions shall be followed for working around energized electrical equipment in accordance with TVA Safety Procedure 1021.

B. Steps may be repeated if all components cannot be tested in a step. However, if the test has been exited, prerequisite steps must be re-verified and a Chronological Test Log (CTL) entry made.

C. Component tags and labels may differ slightly (abbreviations, punctuation, letter case, etc.) from the description given in this test. If this situation occurs, it shall not be considered a test deficiency or procedure deviation. It shall be documented in the CTL and reconciled by way of a plant labeling request, drawing discrepancy, or pen and ink procedure change, as appropriate.

D. All wires removed/lifted from a terminal shall be identified, grouped together, and taped or covered with an insulator to prevent personnel or equipment hazard and possible spurious initiations. The wires should be labeled with the work implementing document number that required them to be lifted if left unattended.

E. All open problems (including non Tech Spec testing acceptance criteria) are to be tracked by a corrective action document and entered on the appropriate system punchlist.

F. Problems identified during the test shall be annotated on the Chronological Test Log (CTL) from SMP-9.0 including a description of the problem, the procedure step when/where the problem was identified, corrective action steps taken to resolve the problem, and the number of the corrective action document, if one was required.

G. Observe all Radiation Protection (RP) requirements when working, in or near contaminated areas.

H. All terminal points and connections are to be considered energized.

Instrumentation must be used to determine if the circuits are de-energized.

I. Retermination of lifted leads requires that their restored bend radius is equal to or greater than the as found condition.

WBN Incore Instrument Room Air 2-PTI-031B-01 Unit 2 Conditioning System Rev. 0000 Page 11 of 128 3.0 PRECAUTIONS AND LIMITATIONS (continued)

J. Transients include pump starts and stops, water hammers or other fluid transients. Check valves should be observed for abnormal slam during startup or shutdown of pumps. Verification that transient conditions are NOT causing excessive vibration may be accomplished by observation during the transient or verification subsequent to the transient that resultant damage has NOT occurred.

K. Steady-state conditions include verification that flow control valves and orifices do NOT produce excessive cavitation induced vibrations. Verification that excessive vibration from other flow induced phenomena does NOT occur is also required.

L. The instrument room chilled water system expansion tank water level shall be inspected periodically. Water level should be above the tank midpoint. To prevent possible overpressurization of the chilled water pump discharge piping, makeup should NOT be added to the system when the chilled water pumps are running.

M. During the performance of this procedure visual observation of piping and components is required. This includes steady-state and transient operations with visual confirmation that vibration is NOT excessive.

N. Ifvibration is determined to be excessive, the Startup Test Engineer (STE) shall initiate a Test Deficiency Notice (TDN).

0. Portions of this test will simulate a high ambient room temperature using an electric heat gun. This activity shall be performed slowly to prevent damage to the temperature switch sensing bulb.

P. During the performance of this procedure, ensure no adverse impacts to the operation of Unit 1 systems, structures, or components.

1) Subsection 6.1 shall be performed first. Subsections 6.2, 6.3, 6.4, and 6.5 may be performed in any order after completion of subsection 6.1. Subsection 6.6 may be performed after completion of subsections 6.1 and 6.5. Subsections 6.7, 6.8, and 6.9 may be performed after completion of subsections 6.1, 6.5, and 6.6. Subsections of 6-,1 this test shall be performed per the flow diagram below:

46.5 6.6

2) When manipulating Contaiment Isolation Valve Handswitches, handswitches must be held in the OPEN position until valve is fully OPEN.

Refer to the following sketch depicting the respective open and closed orientations of Containment Isolation Valves:

[1] VERIFY prerequisites listed in Section 4.0 for SubSection 6.1 have been completed.

NOTES

1) Subsections 6.1.2 thru 6.1.9 may be performed in any order. Steps within these subsections must be performed in the order written.

2) Containment Isolation Valves will be stroke timed locally at the valve, and remotely at the control switch, in the close direction. Local stroke timing begins with the initiating signal, and is concluded with the completion of limit switch actuator movement.

Remote stroke timing begins with the initiating signal, and is concluded with the position indication lights status change on 2-M-9. Stroke time acceptance criteria will be based on the movement to the safety function final position of the valve.

Background Calculations A. Water Flow Instrument Uncertainties Design Flow Rate = 21 ,OPM Flowmeter Uncertainty = + 3% of reading 21 GPM

• 1.03 - 21.63 GPM = 22 GPM B. Air Flow Instrument Uncertainties Air Flow Uncertainties are covered within GTM-05 and are not required to be calculated within this PTI.

C. Valve Stroke Timing Instrument Uncertainties Design Valve Stroke Timing = 10 sec Stopwatch Uncertainty = +/- 0.1 sec Uncertainty is negligible compared to the human error factor involved with use of a stopwatch.
