Dear Sir or Madam:
Luminant Generation Company LLC (Luminant Power) requested relief from ASME OM Code 1998 Edition, through 2000 Addenda, for the testing of the Safeguards Building Sump Pumps (SBSPs) at Comanche Peak Nuclear Power Plant (CPNPP) via Reference 1 pursuant to 10 CFR 50.55a(3)(i).
Reference 2 granted relief on an interim period of up to two refueling cycles but not to exceed 4 years.
This interim relief will end in September 2009.
Luminant Power has provided the information requested per Reference 3 in the Attachment to this letter.

(TAC NOS. MD9722 AND MD9723)
NRC QUESTION The RR states a test can be performed that demonstrates the SBSP can meet its intended safety functions. Please provide a copy of the test procedure that will be used, including acceptance criteria to be utilized, to determine acceptable pump performance.
LUMINANT POWER RESPONSE Procedures OPT-518A/B, "Safeguards Building Sump Pumps and Check Valve Test" are enclosed. Acceptance criteria are included in the procedures.
- 2. NRC QUESTION The RR states the SBSP test will require pumping the same quantity of fluid along a repeatable system path, while measuring flow and vibration. Please describe how the flow rate is measured or determined. Also, discuss any system parameters associated with the flow path that will affect the results of the test and how those parameters will be controlled such that repeatability is achieved.
LUMINANT POWER RESPONSE The flow rate is measured using an ultrasonic portable flow measurement instrument.
This instrument straps on the outside of the SBSP discharge pipe. System configuration is established in OPT-518A/B assuring that a repeatable system flow path will be utilized each time.
The factors that could potentially affect the repeatability of the test are:
- a. any changes in system resistance, and
- b. degradation in the in-line check valve.
These factors are addressed as discussed below:
- a. The system resistance changes can be due to different valve line-ups, throttling of flow, or additional flow sources. This is being addressed by ensuring that the valve line-ups are verified and other sump pumps are
.turned off during the performance of the test using procedure OPT-518A/B "Safeguards Building Sump Pumps and Check Valve Test."

(TAC NOS. MD9722 AND MD9723)
- b. Degradation in the pump discharge check valve could result in a change in flowrate and affect the repeatability of the test. However, this specific test and flow path are also used to perform open and closed tests of the pump discharge check valves. Therefore, failure to meet the flow requirement or trends of degradation in flow will result in evaluating or repairing the pumps and discharge check valves.
- 3. NRC QUESTION The RR states the required SBSP head to pump to the Waste Holdup Tank is greater than the required head to discharge to the Floor Drain Tank, which is the normal lineup. Please discuss the safety-related lineup of the sump pumps and how the discharge head required during testing and normal operation differs from the discharge head required during emergency conditions.
LUMINANT POWER RESPONSE The design flow for the SBSPs is 50 gpm at no specific head requirement. The' SBSPs are designed with a capacity of 50 gpm due to a flange or mechanical seal passive failure to the ECCS pumps. The SBSPs are designed to deliver to both the waste holdup tank and the floor drain tank. The normal lineup is also the same as the emergency line-up which is discharging to the floor drain tank. However, it is permissible to be aligned to the waste holdup tank during normal operations and realignment is not required during an accident. The path to the waste holdup tank (which is our proposed test path) has a greater system resistance due to the piping configuration. Therefore, testing to the waste holdup tank is a more stringent test to verify the design flowrate of 50 gpm.

9/0 all This revision'adds steps to sections 8.1 and 8.2 to align the Safeguard Building Sumps to the Waste Holdup Tank during flow testing. Step added to section 9.0, Restoration to restore the Safeguard Building Sumps to the Floor Drain Tank.
9/1 3, 4, 5, 6, 7, 8 Remove reference to a pressure gauge in the Prerequisite section. The pressure gauge is longer required for this test procedure. Only two operators are required for this test since maintenance will read the portable flowmeter. Change step 5.1.1 to not allow floor drains to overflow instead of the sump. Change step 8.1.4, 8.1. 9, 8.2.4 and 8.2.9 to ensure the flow equipment has also been installed.
9/2 6, 8 This PCN changes the label for all Safeguards Building Sump Pumps vibration points from MOH to MH. This change is a result of EVAL-2006-003019-01. These are small motors with only one location for MH, MV and MA, therefore, MIH and MOH are the same point (MH).

Added step 9.1 to verify that the Safeguards Building Sumps are aligned to the Floor Drain Tank.
12/1 1 This PCN changes the label for all Safeguards Building Sump Pumps vibration points from MOH to MH. This changeis a result of EVAL-2006-003019-01. These are small motors with only one location for MH, MV and MA, therefore, MIH and MOH are the same point (MH).
13/0 Added sump X-06 and X-08 breakers to 9.2 to reflect parent procedure changes.

5.1.2 The sump is a potentially contaminated area.
5.2 Limitations None 5.3 Notes 5.3.1 This procedure can be used to satisfy Post Work Testing requirements as long as applicable Precautions, Limitations and Prerequisites are satisfied. IF any section is NOT performed in its entirety, THEN fill in the appropriate spaces on the data sheet and N/A all spaces NOT performed.
5.3.2 Approximately 30 feet of hose will be required for this'test (sump fill options are available).
5.3.3 Filling the sumps can cause water to backup and possibly overflow from floor drains. The sump Hi-Hi level alarm should be approached carefully to avoid overfilling the sumps.
Previous test performance observations have indicated that the Hi-Hi level alarm actuates at approximately one (1") inch below the grating in the floor drains.
5.3.4 On September 27, 2006, the NRC granted interim relief for testing the Safeguard Building Sump Pumps. The interim relief is granted for up to two cycles on each Unit and no more than four years. The purpose of this relief is for CPSES to determine a final solution to this problem. Refer to EVAL-2006-002428-01.

(For Information Only) Record of Changes Page 1 Rev/PCN Affected Pages Description of Change 10/0 ALL Form revised to be consistent with OPT-518B revision. Requirement to place a clearance for pump coupling guard removal (the guards are bolted outside the pump and not near the rotating equipment) has been deleted, hl value is now a fixed value of 15.167 feet, added final position check and IV of for all valves and breakers to the forms.
11/0 ALL New testing limits for the 2-04 pump per EVAL-2005-000556-01-00.
12/0 ALL A revision to OPT-518B changes the procedure purpose. The sump pumps are no longer required to be tested as part of the IST Plan. This procedure only verifies stroke, of the check valves. As a result of this change the title of the procedure has also changed.'
13/0 ALL This revision adds steps to take vibration readings on the Safeguard Building Sump Pumps as part of the interim relief as granted by the NRC per EVAL-2006-002428-01.
14/0 all This revision removes the pump vibration requirements and add a requirement for MOH.
15/0 ALL This revision renumbers sections 8.1 and 8.2 because steps were added to the procedure to align the Safeguard Building Sumps to the Waste Holdup Tank for flow testing. Added step 9.1 to verify that the Safeguards Building Sumps are aligned to the Floor Drain Tank.
16/0 ALL This revision incorporates Safeguards Sump Pump 2-03 and 2-04 vibration data as supplied by EVAL-2007-000058-01.
16/1 1 This PCN changes the label for all Safeguards Building Sump Pumps vibration points from MOH to MH. This change is a result of EVAL-2006-003019-01. These are small motors with' only one location for MH, MV and MA, therefore, MIH and MOH are the same point (MH).
16/2 1 Updates Safeguards Sump Pump 2-03 vibration data as supplied by EVAL-2008-002402-02.
17/0 Added sump X-06 and X-08 breakers to 9.2 to reflect parent procedure changes.
