AUG 211980 Docket No. 50-317
-318 MEMORANDUM FOR:
E. L. Jordan, Assistant Director for Technical Pr.ograms, Division of Reactor Operations Inspection, IE FROM:
R. V. Woodruff, Sr. Reactor Inspection Specialist, Technical Programs, Division of Reactor Operations Inspection, IE
SUBJECT:
TRIP REPORT /CALVERT CLIFFS 1&2 In our. note of June 3,1980, Don Kirkpatrick and I expressed the notion that a generic program for a portable calculator could be developed for calculati.ng RCS leak rates for most PWRs. Based on that notion, we visited a Westin plant (Farley) and a CE plant (Calvert Cliffs) to obtain plant specific' ghouse data needad for the calculations and -to test the program. Don had previously visited a B&W plant.(Three Mile Island). Our visit to Farley was documented in our memorandum of August 14 and Don's visit to Three Mile Island was made in conjunction with the post-accident followup work.. The visit to Calvert Cliffs completed our effort on demonstrating the usefulnoss of this sort of calculation.
We have written a general program for the HP41C which is enclosed and will calculate RCS lea ~k rates for most reactors from any of the PWR vendors.
To use the program for a specific reactor, magnetic cards must first be written which store the needed design data for that unit. The content of these data cards for Calvert Cliffs 1&2, Farley 1, and Three Mile Island 2 are printed on page 7 of the enclosure. Eacn set of cards identifies the plant and unit and states:
o whether or not separate pressurizer relief and RCS drain tanks have been installed the. units of measurement for expressi.ng tank levels o
o whether or not the pressurizer relief tank level instrumentation is temperature compensated o the ranges of applicability for input variables coefficients for conversion of liquid levels to liquid volumes.

l E. L. Jordan 2
AUG 211980' During the calculation, the user reads these cards into the. calculator when it prompts the user for them. Likewise, the user keys in leak rate test input data when prompted.. The input data and results are printed as shown in the qualification test calculations for the program shown on page 6 of the enclosure.
Running the test calculation before running an ~ actual case assures the user th'at the program is functioni.ng properly.
~
Calculations for'each of these reactors have also been run on the TI 59..
Although the TI 59 program has not yet been, generalized to make it applicable j
i to any PWR, we believe that it can be done.
IE has available the following portable prograrunable calculators with printers:
RI 2
TI 59s RII.
1 TI 59 RIII 1 TI 59 l.
RIV 1
TI 59 RV 1
' HP 97 HQ None The HP. 97 has roughly half the program capacity.of the TI 59, and the HP 41C has six times th'e capacity of the HP 97.
In addition, the HP 41C has keyboard accessible alpha capability. Using that capability, all of the enclosure was written with the HP 41C.. Through a local supplier, seven TI 59s could
~
be obtained for $2,786 or seven HP 41Cs could be obtained for $5,544..
During the trips Don looked into the accuracy of the licensee's calculations and concluded' that the expected error, for each licensee's technique. is:
TMI 2 1.9.gpm Farley 1 2.3.gpm Calvert Cliffs 1&2 0.1 gpm These results are strongly dependent on licensee practice with regard to test duration and round-off input data. Further, readout oscillation was a problem at Three Mile Island. Since the limit on unidentified leak. age is 1. gpm, the results for Three Mile Island and Farley are clearly not acceptable.
For Calvert Cliffs, we ran our program for one of the licensee's test runs picked at random. The licensee's result was 0.71 spm wMic curs was 0.83. gpm.
The difference may be due to the accuracy to which tank calibration curves were read.
In our view, the results of the survey of the three plants indicate that periodic independent calculation of RCS leak rates by inspectors is warranted.
Further, licensee's should be required to sharpen their technique so that the accuracy of the unidentified leak rate determination is 10". or better.
