• TIME: January 13, 1994, 12:00 Noon SUBJECT OF DISCUSSION:

University Tests and GIRAFFE tests. The attached agenda was faxed to GE l by F. Hasselberg prior to the call.

HIGHLIGHTS:

1. NEDC-32301, " Single Tube Condensation Test Program" is the final-UCB test report we are seeking although it also includes results of earlier MIT tests. The version submitted to the NRC on December 2, 1993 is the preliminary draft that is undergoing the final review at GE. GE expects to complete its final review by the end of January 1994 and advise the NRC should there be significant changes.

2. GE does plan to issue another report later in the year that will include additional data from recent MIT tests and results of their assessment of the university tests. However this report is only 4 in the planning stage and GE is unable to predict when it may '

become available. It is not expected within 6 months.

3. To the best of their knowledge, GE does not anticipate that the new test data from UCB and MIT would result in any modification to the condensation heat transfer model (the Schrock correlation) currently used in the TRACG analyses, although that possibility ,

cannot be ruled out completely. T. Lee did mention to GE that results of our preliminary assessment at INEL, using RELAP5, appear to show that the Schrock correlation over-predicts the heat flux in high pressure, high shear flow conditions typical of SBWR isolation condensers.

4. Regarding our RAI for the GIRAFFE facility data (geometric descriptions), GE advised that the best approach is to visit the site as suggested by Mr. Arai of Toshiba to collect necessary data there. Although GE is doing its best, there appears to be some difficulty obtaining the information we need. GE will coordinate

s with Toshiba to arrange our visit and asked when we would like to make the trip. T. Lee indicated that it will take about one month to process our foreign travel papers. GE will attempt to arrange our visit to Toshiba sometimes between February 20 and March 11, 1994. When asked how long we need to be there, T. Lee ~ indicated that it depends on how well the records are kept by Toshiba. If as-built drawings and related documents are complete, it-probably

.will take only a couple of days to copy down all necessary. .

information, but it is more likely that we will not be able.to get all necessary data from the records. Therefore, on-site . .

measurements of the facility is a distinct possibility. To be on the safe side, T. Lee requested that we are allowed four to five days' stay. BNL is requested to submit the foreign travel papers to the NRC immediately. Because the possibility of on-site measurements of a full height facility, BNL requested to send two individuals on the trip.

5. A concern was raised about the possibility of similar delays-in obtaining information we may need from other SBWR test programs.

GE commented that they do not expect to encounter the same i difficulty with the PANTHERS the and PANDA programs. GE will try.

its best to accommodate our information need in a timely manner.

PROPOSED AGENDA FOR CONFERENCE CALL WITH GE UNIVERSITY TESTS

1. When the final UCB test report will be available to us ? How are these test data to be used in SBWR design certification ? Does GE plan a modification of the Schrock correlation ?

2. In NEDC-32301, Single Tube Condensation Test Program, GE indicated that another report will be issued later this year on the university tests (See the last sentence on page 1-3 of NEDC-32301). What is the objective of this report ? When the report will be available to us ?

3. It appears that the new report will include additional data from the current work at MIT that were not mhde available to us before. Is this work funded by GE ? How these data will be used in the design certification ? Will it affect the condensation heat transfer correlation used in TRACG ?

GIRAFFE TESTS Backaround of RAI: i RAI for GIRAFFE tests was first raised with Dr. A. Rao in December 1992 during a meeting with GE in 0WFN. A conference call was arranged among ,

NRR, INEL, and GE on January 27, 1993 in which GE suggested to provide a tape containing a TRACG input deck used for analyses of the GIRAFFE tests. It was hoped that the input deck would contain enough data for the NRC/RES contractor to develop a RELAPS input deck for independent evaluation of GIRAFFE test results. The TRACG tape was not received until April 14, 1993 because GE had to clear with Toshiba on the proprietary consideration. It was not accompanied by related documents (such as noding diagram, calculational sheets, etc.) that are necessary to decipher numbers in the tape.

BNL reviewed the tape and identified the needs for additional information in RAls 950.17 through 950.21 that were transmitted to GE by the letter to Mr. P. W. Harriott on August 20, 1993. Our request for the facility data was explicit in RAls 950.17 and 950.18. During our visit to GE in San Jose at the end of October 1993, we were shown GE's ,

responses to these RAls that were sent to the NRC while we were l travelling to GE. We felt the responses did not address our RAIs completely and so advised Ms. K. Vierow in a meeting in her office.

Information gaps were identified to her in a hand-written list that was later typed and included in our and BNL's trip reports. At our request ,

BNL has updated the list in a fax dated January 4, 1994. A copy of the fax is attached. We indicated to Ms. Vierow that the facility data are needed by January 1994 when RELAPS analyses of GIRAFFE tests were projected to start. Ms. Vierow indicated that she will take up

with her management and talked to Toshiba. However, in an earlier meeting, Mr. Aral from Toshiba did indicate that it would be difficult to give out the facility design drawings that thy consider to be their property, but he does not expect it to be a problem if we are willing to visit Toshiba to copy relevant data from drawings or documents in their file.

Questions:

1. Will the GIRAFFE facility data be made available to us, and when ? The TRACG tape we received contains only an input deck for the Phase I tests t' at, we were told, has not been QAed; it does not contain information on the Phase II tests. Therefore, we need relevant facility drawings and/or documents so that we can develop RELAPS input decks for both phases of the tests using data that can be referenced.

2. Delays in obtaining necessary information are really cutting into our schedules. We are prepared to go out to Toshiba to expedite the process. Can GE arrange with Toshiba to accommodate us ?

3. We are concerned about delays in obtaining information we need to evaluate SBWR experiments. It appears to us that GE's foreign partners can block or delay dissemination of information concerning these cooperative experimental programs using a proprietary claim. What is GE doing to improve the situation ? We need a firm commitment on GIRAFFE as well as PANTHERS and PANDA.

. Request for Additional Information (RAI) for GIRAFFE January 4,1994 The following information on GIRAFFE is needed to have a sufficient geometrical description to model the facility. The August 5,1993 RAI from BNL to NRC had 6 questions that were partially answered in the October 19,1993 letter to NRC (directed to Mr. Jerry N.

Wilson, letter MFN NO 166-93, Docket STN $2004). After examining the response from GE, ., _

the following information is needed to finalize the facility description and acquire missing -

information in RAI 950.17, 950.18, 950.19, ...J 950.20. . Addendums to the four previous questions are below along with one additional question.

A. The following quantities were not in the response to RAI number 950.17, but are needed:

1. Pining Diagrams - It was requested that GE provide piping diagrams to determine the lengths, elevations, diameters, and any corresponding losses within the piping. In a previous RAI GE provided a TRACG deck that has the Phase I configuration, but the deck was not QAed and cannot be considered the final source. The piping diagrams for Phase 1 and Phase 2 experiments are both requested.

2. Phase 1. Steo 1 Tests - The tests have a vent line from the RPV to the Wetwell/ Suppression Pool to equalize pressure in the system. This line is not described in the GIRAFFE Report. Please provide the length and diameter of this line. Furthermore, a valve was used to sent the Wetwell to keep pressure in the -

RPV at a constant value. Please provide a geometrical description of the valve ,

and the settings that opened and closed the valve during the tests.  ;

3. Phase 1. Steo 2 Tests - In this test, the condensate and N2 was sent to the RPV, The U-bend in the return line was removed. Please provide the piping diagram for the lengths, elevations, diameters, and any orifice plates that are present within this pine.

5. Phase 2 - Please provide a geometrical description of the test. The exact configuration of the facility is not present in the GIRAFFE report.

3. A response to RAI number 950.19 is missing from the document received.

C. In RAI number 950.20 we are requesting that the information used to make the plots in the report be supplied to us since the resolution of the plots in the GIRAFFE Report are impossible to read. Furthermore, it would help us with our comparisons to RELAPS if the plots in the report were provided in a digital form.

D. Mav-WntJ)mav Heat Curve - A description of this decay heat curve should be provided and how it was applied during the tests.

E. Please provide a better description of the surface heaters used during the experiments to control heat loss to the envirenment. A discussion of the procedures used to establish the method would be essential to understanding the data collected and its impact on the results.
