SUMMARY

OF FEBRUARY 25,1999, MEETING WITH ABS COMBUSTION ENGINEERING REGARDING ISSUES RELATED TO  !

ABB -CE's CROSSFLOW ULTRASONIC FLOW MEASUREMENT  ;

DEVICE l

On February 25,1999, a public meeting was held at the U.S. Nuclear Regulatory Commission's l (NRC's) offic es in Rockville, Maryland, between members of ABB Combustion Engineering i Naclear Power (ABB-CE), Advanced Measurement Analysis Group (AMAG), utility, and NRC i

staff. Attachment i lists attendees at the meeting. Most portions of the meeting involved l

discussion of proprietary information. Arachment 2 is a copy of the non-proprietary material l handed out at the meeting.

l The purpose of the meeting was to provide an opportunity for ABB-CE and AMAG to brief the staff on the capabilities of the ABB-CE/AMAG CROSSFLOW flow measurement system. As proposed by the vendor, the CROSSFLOW system would be used to support a licensing / technical basis for an exemption request from the Appendix K ECCS requirement regarding the 2% core thermal power uncertainty.

During the meeting, ABB-CE discussed CROSSFLOWs historical development and operating l experience. AMAG also demonstrated how the CROSSFLOW system processed data from the l ultrasonic transducers through a proprietary computer program to determine feedwater flowrate, i

The major discussion was centered around the issues related to increasing licensed thermal power by reducing feedwater flow measurement uncertainty by using the CROSSFLOW measurement system. These discussions are summarized as follows:

'* ABB-CE indicated that the increase in licensed thermal power would be justified based on the improved feedwater measurement accuracy provided by the CROSSFLOW D measurement system. ABB-CE intends to submit to the staff a generic topical report for the CROSSFLOW system in support of licensee's individual power uprate initiatives.

F. Akstulewicz -2 March 11, 1999 e it was suggested that the topical report contain performance information for  :

CROSSFLOW including basic hardware information and other accompanying issues l including system reliability, operation, and maintenance practices. ABB-CE sed that all the necessary information is available; all it needs is to package the report in the appropriate format.

e The staff noted that the Commission has recently approved E rulemaking plan for modifying Appendix K to relax the required assumption in ECCS analyses that the plant i is operating at 1.02 times licensed power. In the interim period, the staff will entertain '

exemption requests from plants that can justify a lower assumed power level. However, without a lead plant requesting an exemption, the ABB-CE's topical report on the  !

CROSSFLOW would not receive a priority review. It was agreed that the review of the ,

topical report could occur prior to and separate from a licensee submittal for a power uprate. The staff also pointed out that each licensee still has to meet all of the non-Appendix K requirements for a power uprate even after an exemption is in hand or after Appendix K has been amended by rulemaking.

l The representatives of the NRC, ABB-CE, AMAG, and utility agreed that this meeting was  !

useful in accelersting the information exchange.
