1.0 INTRODUCTION

1.1 Test Objectives A. Demonstrate the proper operation of the Reactor Building Lower Compartment Cooling Units. B. Demonstrate the proper operation of the Essential Raw Cooling Water (ERCW) control valves associated with each Lower Compartment Cooler (LCC).

1.2 Scope NOTES 1) 2-PTI-030L-01, HFT Containment Temperature Survey, will demonstrate the Lower Compartment Coolers ability to maintain design temperatures. 2) ERCW flowrates are verified during performance of 2-PTI-067-02-A and 2-PTI-067-02-B, ERCW System Flow Balance Train A and Train B. 3) ERCW Temperature Control Valves logic is tested during performance of 2-PTI-067-03, ERCW Valve Logic Test. 4) System vibration testing will be performed during performance of GTM-05, HVAC Air Balance for this system.

This test demonstrates the operability of the Unit 2 Lower Compartment Coolers to ensure the following: A. The LCC Units operate correctly from their respective handswitches in the Main Control Room and on the 480V Shutdown Boards, and their indicating lights indicate correct status. B. Each LCC Unit stops on a simulated Phase B Containment Isolation Signal, and remains off when the signal is reset C. Each LCC Unit stops on a simulated Bus Undervoltage condition (Loss of Offsite Power). D. The air inlet and outlet temperatures for each LCC can be monitored on the Plant Computer System. E. LCC Units backdraft dampers open and close upon start and stop of their respective LCC.

1.2 Scope (continued)

F. The LCC Units maintain design air flows. G. The LCC Units will operate correctly during accident conditions.

H. Each ERCW control valve modulates open upon start and closes upon stop of its associated LCC. I. The following features function only when the LCC Units Transfer Switch is in AUX: 1. Each LCC Unit can be started manually while a simulated Phase B Containment Isolation Signal is present. 2. Each LCC Unit restarts after a time delay when a simulated Loss of Offsite Power (LOOP) is restored. 3. Each LCC unit starts on low flow condition from any other LCC to maintain 3 of 4 coolers in operation.

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. 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 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. IF/THEN steps may be marked N/A if stated condition does not exist.

E. 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. F. All terminal points and connections are to be considered energized.

Instrumentation must be used to determine if the circuits are de-energized. G. Retermination of lifted leads requires that their restored bend radius is equal to or greater than the as-found condition. H. LCC Circuit Breakers have Overload Trip Switch (OTS) reset coils. Placing the Handswitch to STOP will energize the OTS Reset Coil and reset the OTS. The

OTS Reset Coil should only be energized momentarily; the OTS contact in series with the coil should open to de-energize the coil. To avoid overheating

the coil, do not hold Handswitch in STOP if the coil does not de-energize. I. When installing fuses with actuators, ensure that the actuating rod is oriented correctly to provide for proper alarm initiation and visual indication. J. All open problems are to be tracked by a corrective action document and entered on the appropriate system punchlist.

Data Package: Page ____ of ____ Date ________

3.0 PRECAUTIONS AND LIMITATIONS (continued)

K. 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. L. Observe all Radiation Protection requirements when working in or near radiological areas. M. Ensure there are no adverse effects to the operation of Unit 1 structures, systems, or components. N. Vibration testing of this system is performed during the GTM-05, HVAC Air Balance for this system. O. During the performance of this procedure, visual observation of fans and ductwork is required. This includes steady-state and transient operations (fan starts and stops) with visual confirmation that vibration is not excessive. P. To verify that transient conditions are not causing excessive vibration, observe components (duct, dampers, fans, etc) during the transient, to the extent practical. If not practical to observe during the transient, verify after the

transient that no damage has occurred. Q. If the vibration is determined to be excessive, the Test Engineer shall initiate a Test Deficiency Notice. R. LCC control switches in the Main Control Room may NOT be placed in PULL A-P AUTO. Auto-start features enabled by this switch position are

disabled and are not tested in this instruction. S. The Setpoint and Scaling Documents for the Time Delay Relays that cause the LCCs to automatically start after bus voltage is restored (after a Loss of Offsite

Power) have been voided and these relays are no longer calibrated. Therefore, their response times will be described as approximately 1 minute in this

instruction. Reference EDC 50345 and EDC 50330 for further information.

Measurement uncertainties for parameters measured in this test must be incorporated into the test acceptance criteria 1.0 Motor Design Density Horsepower From Reference 2.2C.4, the Lower Compartment Cooler Fan Motors Nameplate Horsepower is 60 HP and the Motor Horsepower at Design Density conditions cannot exceed the Nameplate Horsepower.

Assuming each measured current and voltage values are within 2.4% as given in Reference 2.2C.1, then the adjusted Motor Horsepower and Design Density (HPDD) can be calculated:

1.0 Motor Design Density Horsepower (continued)

Assuming that the Barometric Pressure (B) and Temperature (T) are within 0.4% of range (27-31 inHg) and 2F, respectively, as given in Reference 2.2C.1: 0.4% of 4 inHg = 0.016 inHg The Maximum percent error for the Barometric Pressure would occur at the lower end of the scale with an indicated Barometric Pressure of 27.00 inHg and an actual

Barometric Pressure of 27.016 inHg.

00059.0 16.27 00.27 1 This equates to a maximum error of 0.059% The Maximum percent error for the Temperature would occur at the lower end of the scale with an indicated Temperature of 32F and an actual Temperature of 34F 0588.0 34 32 1 This equates to a maximum error of 5.88% Looking at the equation for Test Density (D T): Assuming that the numerator has an error equal to that of Barometric Pressure (B), and the denominator has an error equal to that of Temperature (T), the total maximum

error of Test Density will be:

%00.1%88.5%059.0 Therefore, D T may only be 99.0% of its actual value.
