A COMPARISON BETVEEN RETRAN-02 MOD 3 &

RETRAN-02 M004 AND ITS IMPACT ON

, , OYSTER CREEK RETRAN MODEL Revision 3 of Reference 1 identifies the changes made from MOD 3 to M004 This list is reproduced in Attachment 1. This list has been checked out against the source updates description of file #3 of RETRAN transmittal tape which was sent to the NRC 1ast November as part of the above issue. The conclusion of this comparison is that there is no modeling changes, or changes in equations used in MOD 4 except as noted below:

1. Revised Critical Flow Transition Calculation - Section IV.3.6 shown in Attachment 1:

This calculation was implemented for the iscenthalpic option (see Reference 1)'which was not activated for the Oyster Creek Model (Moody option was used).

l

2. Control Rod Model: This revision is described in detail in Reference

1. GPUN motivation for using this model is described in Attachment 2 where a comparison was made for the Oyster Creek Cycle 1 startup tests l benchmark which revealed the necessity for the new rod nr ici . It was also found that the interpolation scheme during rod ente" 4 .- :r end

, of cycle Turbine Trip Without Bypass was not adequate :c sb w a reasonable comparison against vendor's data. Based t tP M experience, it was decided to use the new red model for r- m appl ication.

3092C

3. Correction in the mass equation for the pressurizer liquid and vapor regions ;Section VI.6.2.1,2 (Attachment 1). This correction deals 3

with mass transfer between vapor and ifquid regions due to 1

condensation on vessel walls in the vapor region of a non-equilibrium vol ume. This effect takes place only when the local conditions heat transfer model is activated. For the Oyster Creek model, there are no stack conductors and th'e local conditions heat transfer model is not used.

A comparison between four sarple problems run on MOD 3 and MOD 4 and documented in Reference 1, Volume 3 show deviation of less than 0.1% on major edits p arameters . This deviation is believed to be due to the dif ferent compilers used since MOD 3 used the H Cc,mpiler where M004 uses the FORTRAN 77 Compiler.

The four problems were: ,

1. EDWARD PIPE

2. Standard Problem #4 - NRC's CASP Series (T1 TA Test 4906)

3. Sample Problem f5 - TTWOBP Using Point Kinetics 4 Suple Problem f9 - TTWOBP Using one-Dimensional Kinetics The results of problems 3 and 4 above have been reproduced in Attachment 3 where Rev. 2 on the lower right/left corner of the figures indicate MOD 3 results while Rev. 3 indicate MOD 4 output.

1 I

It is concluded that the options of the code used for the Oyster Creek model in MOD 4 are the ones already approved by the NRC (except for the Rod Model).

CHANGE PAGES FOR EPRI NP-1850-CCM VOLUE I RETRAN THEORY W UAL The pages listed below are the replacement pages for the RETRAN-02 Theory Manual which art associated with various changes resulting from the M00004 code modifica-tions. These pages are either replacement pages for those with the same page nurreer in Revision 2 of the Theory Manual distributeo by EPRI for RETRAN-02 M00003, or additional pages for those with new page nutreers. Those pages which have changes are indicated by "Revision 3' in the lower, outside corner of the page, and the change is indicated by a vertical bar along the change.

Some of the changes are associated with error corrections for the M00003 code version. All other changes are either associated with M00004 code modifications (e.g., the trultiple control sttte control rod model), minor changes to correct gearrmatical or typographical errors, or changes to clarify the original text.

As ae discussed in our meeting on Feoruary 19, 1956, I am foraarding to y u tne ,areliminary results of the testing we have done witn the new control ro:

inocel in SIMT<AN anc RdTRAN. Tne testing was performec with a mocifiec version of diTRAh02 M0003 witn tne ne. control rod model tnat was proviaec to us oy EPRI in response to tne aoove reference. A modified version of 01MTKmh aas also proviceo.

1 ine testing aas performed using cata for a turoine trip performeo curing ;

Ojster Creek (UC; startup testing. Tne control roc density at the time of :

tne test was 24.1% (See Figure i for the control rod pattern). Tne nign roc aensity makes tnis a good test for the new control rod model and hignlignts tne ceficiency in tne current control roa mocel. Some of tne easic cata for '

tne test is includea in Tacle 1.

Tne input to blMTRAN anc RETRAN was identical for the two models, except for input enanges required for the modification. Tne results for this transient using tne tao RiikAN mocels are snoan in Figures 2 and 3. Figure 2 snows l l

'/ ERROR DESCRIPTION:

r/ '

'/ HEAT TRANSFER MODE 16 CAN NOT BE COMPUTED DUE TO BAD NUMBERS FOR

'/ CP AT THE NEIGHBORHOOD OF CRITICAL PRESSURE. THE COMPUTED VALUES

'/ FOR CP FOR THESE CASES ARE THE ORDERS GF -10**4. (SEE PROBLEM

'/ REPORT NUMBER 212.)

'/

'/ MODIFICATION DESCRIPTION:

'/ )

'/ THE PROBLEM IS A RESULT OF INFLECTION POINTS IN THE "SURFACE FITS" l

'/ USED TO APPROXIMATE THE TEMPERATURE OF WATER AS A FUNCTION OF ITS

'/ PRESSURE AF0 ENTHALPY IN THE NEIGHBORHOOD OF THE CRITIAL POINT.

/ SPECIFICALLY, FOR PRESSURES RANGING FROM APROXIMATELY 3208.0

'/ (0.2 PSI BELOW THE CRITICAL PRESSURE) TO APPROXIMATELY 3700 PSI,

'/

AND FOR ENTHALPIES RANGING FROM APPROXIMATF.LY 850. TO 906. BTU /LB,

/ THE TEMPERATURE FUNCTIONS GO THROUGH A RELATIVE MINIMUM, SLIGHTLY

'/ TO THE LEFT OF THE CRITICAL POINT (H=906). AS A RESULT THE HEAT (;

'/ CAPACITY (1/DTDH) BECOMES NEGATIVE NEAR THE CRITICAL POINT. TO

/ ELIMINATE THE PROBLEM, SUBPROGRAM WATER WAS MODIFIED TO CUT OUT THE l

/ "BAD" PORTION OF THE LIQUID TEMPERATURE "SURFACE FIT" (H<906.) AND '

l

/ REPLACE IT WITH A RULED SURFACE "PATCH" BETWEEN BOUNDING AREAS OF

/ THE ORIGINAL SURFACE. THE RESULT HAS THE EFFECT OF KEEPING THE

/ TEMPERATURE FUNCTION (STRICTI Y) MONOTONICALLY INCREASING WITH l

/ ENTHALPY FOR FIXED PRESSURE. THE HEAT CAPACITY IN THIS REGION IS )

/ CONSTANT AND THE DERIVATIVE OF THE TEMPERATURE WITH RESPECT TO PRES-

/ SURE FOR A FIXED ENTHALPY IS LINF4LY WEIGHTED SIMILARLY TO THE TEM-

/ PERATURE FUNCTION. THE RULED SUrbACE IS USED BETWEEN 800. AND 906.

/ BTU /LBM FOR 4LL PRESSURES GREATER THAN 3208.2 AND PRODUCES TEM-6/ PERATURES IF BETTER AGREEMENT WITH THE ASME VALUES THAN THE

/ ORIGINAL SU7 FACE IN SOME AREAS. THE DISCREPANCIES BETWEEN THE

/ MODIFIED FUNCTION VALUES AND THE ASME VALUES ARE WITHIN THE SAME

/ ERROR BOUND AS THE ORIGINAL FIT. IN THE SMALL WINDOW BETWEEN 3208.0

/ AND 3208.2 PSI, AND 903. AND 906. PSI NEGATIVE HEAT CAPACITIES ARE

/ ALSO COMPUTED (DIFFERENT SURFACE FIT THAN THE ONE DISCUSSED ABOVE).

/ TO AVOID CODE FAILURES RESULTING FROM THESE NEGATIVE VALUES, THE

/ ABSOLUTE VALUE OF THE COMPUTED HEAT CAPACITY IS RETURNED. IN THE

/ ORIGINAL WATER PROPERTIES, THERI WAS A DISCONTINUITY IN THE TEM-

/ PERATURE AT 906. BTU /LB FOR PRESSURES EXCEEDING THE CRITICAL POINT.

/ THIS CORRECTION ELIMINATES THIS DISCONTINUITY BUT INTRODUCES A

/ DISCONTINUITY AT THE CRITICAL PRESSURE FOR ENTHALPIES BETWEEN

/ 800. AND 906. BTU /LB.

/

/ THE MODIFICATION REQUIRES NO INPUT MANUAL CHANGES AND DOES

/ NOT ALTER DATA TAPE STRUCTURE, BUT THE THEORY MANUAL NEEDS

/ TO BE MODIFIED TO REFLECT THE USE OF THE RULED SURFACE l

/ BETWEEN 800 AND 906 BTU /LB FOR PRESSURES EXCEEDING THE CRITICAL (

/ POINT.

/ THE ORIG 7NAL ERROR COULD NOT BE RE-CR ATED BECAUSE IT HAD OCCURED

/ AFTER SEVERAL RESTARTS WITH CODE UPDATES AND THE HISTORY UAS NOT

/ RECORDED. THE INITIAL PORTION OF THE RUN WAS EXECUTED TO SHOW THAT

/ THE MODIFICATIONS DON'T CAUSE ANY IKEDIATED PROBLEMS.

/

/ VERIFICATION:

/

/ THE ORIGINAL CODE MODIFICATION CONTAINED AN ERROR IN THAT THE HEAT

/ CAPACITY WAS NOT CONSTANT IN THE REGION WHERE THE TEMPERATURE WAS

/ COMPUTED AS A LINEAR FUNCTION OF THE ENTHALPY FOR A GIVEN PRESSURE.

/ THE COMPUTATION OF THE PARTIAL DERIVATIVE OF THE TEMPERATURE WITH

/ RESPECT TO THE ENTHALPY WAS ALSO MODIFIED TO BE CONSISTENT WITH THE LINEAR WEIGHTING. THE LOWER ENTHALPY BOUND FOR THE RULED SURFACE

~

/

/ WAS MODIFIED FROM A FUNCTION OF PRESSURE TO A FIXED ENTHALPY OF

/ 800 BTU /LBM AND THE RULED SURFACE IS APPLIED FOR ALL PRESSURES ABOVE

/ THE CRITICAL POINT. A DRIVER SUBROUTINE WAS WRITTEN TO EXERCISE

/ THE WATER PROPERTY FUNCTIONS FROM 3150 PSI TO 6000 PSI FOR ENTRALPIES

/ RAN3ING FROM 800 TO 906 BTU /LB. THE RULED SURFACE INTERPOLATION

/ ELIMINATED THE PROBLEMS OBERVED WITH THE ORIGINAL FITS (NEGATIVE

/ HEAT CAPACITIES). THE MODIFIED CODE WAS ALSO VISUALLY VERIFIED TO

/ TO BE CORRECT.
