Attention: Ms. E. G. Adensam, Chief Licensing Branch No. 4 Re: Catawba Nuclear Station Docket Nos. 50-413 and 50-414

Dear Mr. Denton:

Ms. Elinor G. Adensam's letter of April 10, 1984 transmitted three questions (as Enclosure 4) which were related to Open Item 5 in the Catawba SER, Thermal Design Procedures and Flow Measurement Techniques. A response to each of these questions is attached.

As the response to question 1 contains information proprietary to Westinghouse Electric Corporation, it is supported by an affidavit signed by Westinghouse, the owner of the information. The affidavit sets forth the basis on which the information may be withheld from public disclosure by the Commission and addresses with specificity the considerations listed in paragraph (b)(4) of Section 2.790 of the Commission's regulations.

Accordingly, it is respectfully requested that the information which is proprietary to Westinghouse be withheld from public disclosure in accordance with 10 CFR Section 2.790 of the Commission's regulations. Correspondence with respect to the proprietary aspects of the Application for Withholding or the supporting Westinghouse affidavit should reference CAW-84-33 and should be addressed to R. A. Wiesemann, Manager, Regulatory and Legislative Affairs, Westinghouse Electric Corporation, P. O. Box 355, Pittsburgh, Pennsylvania 15230.

DW Accuracy = [0.00007)(4500)+ 2 (.010)] = 0.05150-The ncminal output for the hot leg RrDs is 450 n.

The sensitivity to a change of the Rr0 or in resistance is AT the change in temperature with respect Frcm the Westinghouse design .

The other measured parameters that are required in the' Westinghouse analysis to be calibrated within a specified (7) day period are:

Primary RTD Digital Voltmeter Feedwater Temperature Process Components AP Cell for Feedwater Flow The Digital Voltmeter used to measure the primary RTDs will be calibrated within seven (7) days prior to the perfomance of the precision heat balance.

The feedwater temperature is measured by precision test Type - J themocouples which are of higher quality than the process temperature sensors referenced in the generic submittal. These themocouples are regularly calibrated and equipment histories indicate the 0.25F calibration accuracy, providing-the ther-moccuple is not physically abused is The accuracy quoted for the Digital Themogood couplefor the annual includes Themometer calibration an cycle.

annual drift alkwance.

The feedwater flow AP is read by the Ruska DDR-6000. The accuracy previously quoted in question 1 was a 90-day specification that included an allowance for instrument stability (drift). A calibration check on the Ruska DDR-6000 will be perfomed within 90 days of perfoming the precision heat balance.

Provisions will be included in the procedure for insuring the calibration of.

these instruments within the specified period.

flou, should be measured and treated as a bias, i.e., the error due to venturi .

fouling should be added to the statistical sumnation of the rest of the measure-ment errors".

a) ^ Hou do you assure that the venturi is clean at' the beginning of a cycle?  ;

. Is the venturi cleaned at the beginning of every cycle? l b) Hou do you detect the venturi fouling and to what extent [of-uncertainty can you detect fouling? - _.

c) ~ Describe the design provisions 'and procedures to clean the venturi if _ -

d) Hou do you determine the error on feeduater flou measurement due to the

e) If the venturi is not cleaned prior to the calorimetric flou measurement because no fouling is detected, an error component should be added. The magnitude of the error component should depend on the minimi.m detectable value of fouling.

Response '

(a and c) The feedwater venturis will be assured to be clean by benchmarking trended parameters at the beginning of the first fuel. cycle. Presently, no provisions cycle. exist for cleaning the feedwater venturi at the beginning of every (b, d, and e) The Catawba Perfomance Monitoring Program includes a monthly review of trended data conducted for the purpose of detecting potential venturi fouling. The undetected development of venturi fouling during a power cycle would introduce a non-conservative bias into any subsequent efforts to nomalize the RCS elbow tap flow indications. The monthly review includes analyzing trended data of electrical output, feedwater flow and 1st stage pressure.

The ratios of electrical output and 1st stage pressure to feedwater flow would shift in the event of venturi fouling and are, therefore, monitored to detect fouling. Indicated reactor themal power is directly porportional to indicated feedwater flow. Venturi fouling would result in an increase in indi-cated feedwaer flow which would increase indicated reactor themal power. Since the reactor themal power is limited to the 100% licensed value, indicated feed-water flow is also limited and actual feedwater flow would be reduced. By reducing actual feedwater flow, electrical output and 1st stage pressure are reduced;by the same degree. Therefore, by trending electrical output and 1st stage pressure with indicated feedwater flow, venturi fouling can be detected.

The nomal relationship between electrical output,1st stage pressure and indicated feedwater flow will be established during the first fuel cycle when the venturi is presumed to be clean. To avoid any significant effect of measure-ment uncertainties on the results, the monthly review will include analyzing data that is trended on a daily basis. The mean electrical output and mean 1st stage pressure will be compared to the mean feedwater flow. If the trend of the monthly reviews indicate that this ratio has deviated by 0.1%, corrective action will be taken before performing the next precision heat balance for RCS flow measurement.

Corrective action will involve either (1) inspecting and cleaning the venturi or (2) quantifing the bias effect of the fouling and making an allowance for it in the RCS flow measurement.

The taken. 0.1% value serves as an " alarm level" at which corrective action must be This value was chosen because it is believed to be high enough to avoid fouling. "alams" yet low enough to avoid an unnecessarily excessive penalty for spurious t
