1.0 INTRODUCTION

1.1 Test Objectives Demonstrate the Emergency Gas Treatment System (EGTS) is capable of providing pressure control and cleanup of the atmosphere in the Unit 2 Containment Annulus.

1.2 Scope NOTE All manual and automatic controls and indications were tested in 2-PTI-065-01.

A. Demonstrate proper operation of the Containment Annulus Vacuum Control Subsystem.

Annulus Vacuum Fans and pressure control dampers work to maintain a specified negative pressure in the annulus during normal operating conditions.

B. Demonstrate proper operation of the EGTS Air Cleanup Unit Subsystem.

EGTS fans and pressure control dampers work to maintain a specified negative pressure, total flow, and inleakage, during post-LOCA (Loss of Coolant Accident) conditions.

EGTS fans work to achieve a specified minimum flow within a certain time period post-LOCA.

3.0 PRECAUTIONS AND NOTES A. Standard precautions shall be followed for working around energized electrical equipment in accordance with TVA Safety Manual 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. Discrepancies between component ID tags and the description in a procedure/instruction if the UNIDs match, exclusive of place keeping zeros and train designators (e.g.; 2-HS-31-468 vs. 2-HS-031-0468) and the noun description is sufficient to identify the component. This condition does not require a TDN in accordance with SMP-14.0. If the component label needs to be changed, a Tag Request Form (TR Card) should be processed in accordance with TI-12.14. Make an entry in the CTL and continue testing.

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

E. All open problems 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 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 requirements when working in or near radiological areas.

H. Ensure there are no adverse effects to the operation of Unit 1 structures, systems, or components.

I. Test personnel will coordinate with Unit 1 Operations when manipulating Unit 1 equipment if required.

J. Unit 1/Unit 2 common duct is used for discharging to the atmosphere during operation of the Containment Annulus Vacuum Control Subsystem. U2 Annulus Vacuum Control Fan (AVF) operation may affect U1 annulus vacuum, refer to U1 Tech Spec SR 3.6.15.1.

WBN EMERGENCY GAS TREATMENT 2-PTI-065-02 Unit 2 SYSTEM PRESSURE TEST Rev. 0000 Page 11 of 59 Data Package: Page ____ of ____ Date ________

3.0 PRECAUTIONS AND NOTES (continued)

K. During the performance of this procedure visual observation of duct and components is required. This includes steady state and transient operations (fan stops and starts). Confirm by sight, sound, and touch, that vibration is NOT excessive.

L. If vibration is determined to be excessive the Startup Test Engineer (STE) shall initiate a Test Deficiency Notice (TDN).

M. Vibration testing of this system is performed during GTM-05.

N. Termination of lifted leads requires the restored bend radius to be equal to or greater than the as found condition.

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

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

P. Units of measure for differential pressure are recorded in this instruction as in WG (inches water gage). This is equivalent to in WC (inches water column) and in H2O, which are typical units that may be found on instrumentation used for verification of acceptance criteria.

Q. This procedure requires the performer to determine when system equilibrium occurs by observing various Main Control Room instrumentation. Equilibrium has been reached when the respective instrumentation indicates steady output (no cycling).
