Subject:

Duke Energy Carolinas, LLC Oconee Nuclear Site, Units 1, 2, and 3 Docket Numbers 50-269, 50-270, and 50-287 Request for Additional Information for License Amendment Request for Low Temperature Overpressure Protection System Technical Specification 3.4.12, Surveillance Requirement 3.4.12.7 License Amendment Request (LAR) No. 2008-04 In accordance with 10 CFR 50.90, Duke Energy Carolinas, LLC (Duke Energy) proposes to amend Appendix A, Technical Specifications, for Renewed Facility Operating Licenses Nos.

DPR-38, DPR-47, and DPR-55 for Oconee Nuclear Station (ONS), Units 1, 2, and 3. This LAR requests the Nuclear Regulatory Commission (NRC) to review and approve a change to the technical specification (TS) 3.4.12, Low Temperature Overpressure Protection (LTOP) System, surveillance requirement (SR) frequency, specifically TS SR 3.4.12.7. TS SR 3.4.12.7 currently' requires a channel calibration to be performed every 6 months. The proposed LAR changes the TS SR frequency from 6 months to 18 months. The LAR was submitted August 6, 2009.

On February 12, 2010, a request for additional information (RAI) was received from the NRC concerning documentation of the total loop uncertainty and drift for the new instrumentation.

Enclosure 1 contains the RAI responses. Attachments 1 and 2, respectively, contain applicable sections of the calculations for the LTOP pressure instrument total loop uncertainty.

Attachment 3 contains the requested vendor information.

In accordance with Duke Energy administrative procedures and the Quality Assurance Program Topical Report, this response is still bounded by the initial review and approval of the Plant Operations Review Committee. Additionally, a copy of this response is being sent to the State of South Carolina in accordance with 10 CFR 50.91 requirements.

Duke Energy requests that this proposed license amendment be reviewed and approved in support of the Spring, 2010 refueling outage. Duke Energy will also update applicable sections of the Oconee UFSAR, as necessary, and submit these changes per 10 CFR 50.71(e). There are no new commitments being made as a result of this proposed change.

Device/Loop Uncertainty Term Identification Rosemount Model I 154SH9RB Differential Pressure Transmitters All uncertainties given in this section are for the Rosemount Model 11 54SH9RB Pressure Transmitter installed in the reactor coolant system (Reference 45). The output range for the pressure transmitters is 4 - 20 mAdc corresponding to a calibrated range of 0 - 600 psi.

All uncertainties given below are.random-independent terms unless stated otherwise.

PT3CA - Transmitter Accuracy Per Reference 45, reference accuracy is specified as b- 0.25 % of calibrated span. Includes the combined effects of linearity, hysteresis and repeatability.

PT3CA := 0.25%span PT3D -Transmitter Drift Per Reference 45 the drift is specified as 0.2 % URIJ30 months. The URL for the the Rosemount 1154SH9RB transmitter is 3000 psig while the calibrated span is 0 - 600 psig.

Per Table EP-1 of Reference 46, the normal reactor building temperature varies between 60 - 130 OF. It is assumed that a nominal average temperature at the time of channel calibration is 80 *F. Allowing a potential temperature variation ofk 50 'F about this nominal temperature will cover the expected reactor building temeprature range. Therefore, the transmitter temperature effect is:

Therefore, the transmitter qualifications are bounding with respect to the qualification temperature profile given in Reference 45. This term will be conservatively treated as a two-sided bias.

Reference 45, gives a power supply effect of 0.005 % span/volt. Therefore, a conservative transmitter power supply effect using the 36 Vdc model is:

PT3SP -Transmitter Static Pressure Effect Per Reference 45 the transmitter static pressure effect is systematic and can be calibrated out for a particular pressure before installation. The correction uncertainty is 0.5% of input reading/l,000 psi. Assuming a reading of 600 psi:

Also, a Heise PTE-l with HQS-2 module Pressure Gauge with a range of 0 to 1000 psig is used. The uncertainty, as given in Reference 48 for the Heise pressure gauge, is - 1.7942 psig. Both allowances above assume transmitter calibration occurs at containment temperatures between 55 'F and 92 °F.

Per Table EP- I of Reference 46, the design basis accident reactor building peak radiation following a design basis accident is 61 megarads. Per Reference 45 the accident radiation effect is (0.5 % URL + 1.0 % span) up to 55 megarads and (0.75 % URL + 1.0 % span) after a 110 megarads. Since the peak radiation effect is above 55 megarads and is not expected to be above I 10 megarads the accuracy for 110 megarads will conservatively be used. This term will be conservatively treated as a two-sided bias. The transmitter radiation effect is:

Conclusions The normal condition Low Range Pressure uncertainty results calculated above are within the results calculated previously for this channel (15.7 psi vs. 18.8 psi). An uncertainty allowance of+/- 25.0 psi was used previously to develop the OAC subcooled margin monitor curves in Tables 16, 18 and 20.

Therefore, the curves in Tables 16, 18 and 20 and their associated polynomials will not need to be revised.

The accident condition Low Range Pressure uncertainties presented above are for possible future use as it may be desirable to use the new instrumentation under degraded reactor building conditions for post accident monitoring.

The results for the new instrumentation is also within the low pressure indication uncertainty sensitivity case results presented in Tables C-2 and C-3 (13.2 psi vs. 13.86 and 15.43 psi). Therefore, the sensitivity cases will not be reanaylzed for the new instrumentation in this appendix.

The accident condition Low Range Pressure indication uncertainties presented above are for possible future use as it may be desirable to use the new instrumentation under degraded reactor building conditions.

These transmitters were qualified per IEEE Std 323-1974 and IEEE Std 344-1975 at radiation levels of 110 megarads TID gamma radiation, seismic levels of 8.5 g, and fbr steam-pressure performance. Stringent quality control during the manufacturing process includes traceability of pressure-retaining parts, special OPERATION nuclear cleaning, and hydrostatic testing.

The completely sealed &Cell capacitance sensing element is the key to the unequalled performance and reliability of the Model 1154 Series H Pres.sure TRANSMITTER DESCRIPTION Transmitter. Process pressure is transmitted Model 1154 Series H Transmitters are uniquely through an isolating diaphragm and silicone oil fill built for Class 1E nuclear service, while retaining fluid to a sensing diaphragm in the center of the the basic design of the Model 1151 Series that has 8-Cell (see Figure 1). A reference pressure is become a standard of reliable service. Units are transmitted in the same manner to the other side of available in sealed reference (S), differential (D), and the sensing diaphragm. Displacement of the sensing high-line differential (H) configurations, with a total diaphragm, a maximum motion of 0.004 in. (0.1 of six pressure range options. mm), is proportional to the pressure differential across it- The position of the sensing diaphragm is Direct electronic sensing with the completely detected by capacitor plates on both sides.
