Revision to Administrative Controls Technical Specification 6.9.1.6.
By letter dated August 14, 2014 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML14260A432, STP Nuclear Operating Company (STPNOC, the licensee) submitted a license amendment request (LAR) for South Texas Project (STP), Units 1 and 2, for revision to Technical Specification (TS) 6.9.1.6, "Core Operating Limit Report (COLR)," with respect to the analytical methods used to determine core operating limits.
Specifically, the licensee plans to replace the existing Crossflow Ultrasonic Flow Measurement (UFM) System with a Cameron/Caldon Leading Edge Flow Meter (LEFM) CheckPlus System for measuring feedwater flow.
The NRC staff has reviewed the information provided in this application and determined that additional information is required in order to complete its review. The staff's request for the following additional information:
Test Fidelity and Test Range
- Please provide summary of planned tests representative of the STP configuration.
- Please provide summary of planned test variations to address configuration differences.
NRC Request - RAI I Please provide summary of planned tests representative of the STP configuration.
STPNOC Response:
Attached is the calibration plan for Unit 2 (Attachment 2). The calibration plan calibrates four (4)
LEFM flow measurement spool pieces in piping configurations representative of STP Unit 2, containing Feedwater Piping Loops A, B, C and D. The plan configurations model an upstream portion of the piping as outlined in the attached configuration sketches (Attachment 3).
The STP Unit 2 calibration plan is provided with this RAI response. Unit 2 is being calibrated first to support a spring 2015 installation. A similar calibration plan will be prepared to support the fall 2015 installation in Unit 1.
NRC Request - RAI 2 Please provide summary of planned test variations to address configuration differences.
STPNOC Response:
Attached is the calibration plan for Unit 2 (Attachment 2). The calibration that will be performed for STP Unit 2 regarding the LEFM units is representative of the site configuration. Due to laboratory space constraints STP Feedwater Piping Loops A and D will be calibrated in two phases.

Don Augenstein 1 of 7 1 STP UNIT 2 CALIBRATION PLAN: 18" LEFM METERS AND 18" ASME NOZZLE METERS 1.0 PURPOSE This plan calibrates four (4) LEFM flow meters and (4) ASME nozzles in piping representative of their installation sites at the South Texas Project (STP) Nuclear Power Plant (NPP) Unit 2. The test plan models an upstream portion of the installation piping (refer to SKDTM-24). The final results are calibration coefficients'.
2.0 SCOPE This calibration plan applies to the four (4) 18" LEFMV/+ spool pieces manufactured by Cameron for the STP Unit 2 NPP. In addition the following plan incorporates the pipe models that will be employed during collection of the nozzle calibration data (in accordance with PTC-6 recommendations). The LEFM meters and nozzles shall be installed into the calibration facility in accordance with the referenced documents.
3.0 RESPONSIBILITIES 3.1 Test Facility Responsibilities An independent laboratory, Alden Research Laboratories (ARL), shall be responsible for providing calibrated equipment and test facilities for this test. In addition ARL will be responsible for the Nozzle meter calibration. The nozzles will be calibrated using a 20 point calibration in accordance with PTC-6 recommendations. In order to achieve maximum flow rates and maximum Reynolds numbers, ARL will run their flow loop at their maximum conditions allowable with respect to the model. These test conditions are expected to be in the range as noted in Table 1.
Table 1: Calibration Parameters Parameter Range Fluid Temperature 85°F to 1 10°F (varies with time)
(29°C to 43°C)
Fluid Pressure Less than 65 psig (46,000k g/m2)
Flow Rate 2000 to 16,000 gpm (450 to 3650 cubic meters/hr)
Reynolds Number 0.5 x 106 to 4.2 x 106 3.2 Cameron Responsibilities The Cameron Engineering Department shall be responsible for completing the calibration plan and documenting the results of the test. Only the latest revision of all procedures shall be used for this calibration.
3.3 Prerequisites Prior to the start of the test plan, the applicable sections of the referenced procedures shall be completed.

Don Augenstein 3 of 7 1 5.0 CALIBRATION PROCEDURE OVERVIEW The tests require that the LEFM'/+ spool piece section be set-up in accordance with the appropriate referenced procedures (non-fluid tau only and SNRc). A single 8-path LEFM transmitter will be required to support these tests. Table 2 (following) summarizes the tests performed with a commentary as to the test purpose.
Cameron performs tests to demonstrate hydraulic insensitivity. These parametric tests perturb the model to explore the possibility of sensitivities. Cameron's approach is to radically perturb both the inlet conditions and the model components.
It is noted that if the Cameron engineer determines an alteration to the test sequence is required - then he/she reserves the right to make modifications based upon sound engineering judgment. In addition the test sequence may be altered in an effort to more efficiently perform the noted tests.
Table 2: Test Overview ASME Nozzle Calibration Overview Description Test Commentary Straight Pipe Tests A-3, D-2 (D-3) Purpose is to collect data in order to compute the sensitivity between straight pipe calibration (per ASME PTC 6) and the model calibration.
Plant Model Calibration A-1 Baseline for parametric tests (including B-i(B-3) straight pipe and changes to the inlet C-l(C-2 & C-3) conditions).

Don Augenstein 4 of 7 1 Table 3 provides an estimate of the test plan schedule. The plan attempts to optimize the model sequence to minimize setup time.
6.0 CALIBRATION PROCEDURE Testing will be performed on the spool pieces in the piping configurations outlined below. Testing will be done with a variety of piping configurations including a model of the system. Both pumps shall be used for all the piping configurations and all the flow rates (Note: One pump is an option for the lowest flow rates).
The laboratory shall match the model's pipe length dimensions as specified in this procedure and reference sketches within +/-2 inches (+50 mm). The pipe size and schedule of the upstream pipe that the laboratory uses shall be those specified in the attached drawings. Alternate pipe size and schedules may be used if they agree with the pipe inside diameter (for example 16 inch standard schedule has comparable inside diameters to 18 inch heavy schedule).
Note 1: For all tests, confirm flow rates at maximum flow that the lab can provide without cavitation. The laboratory may have inadequate line pressure such that the fluid might cavitate at the higher flows.
Therefore - some testing is required to determine the maximum test flow rate.
Note 2: The flows to be tested will extend from the maximum flow ARL can provide using the standard Cameron 25-point calibration method from the meter's 10:1 turndown up to the maximum available. For parametric tests - the lowest flow rates are optional or may be substituted for intermediate flow rates.
Note 3: Reference the attached sketch of the models.
