SUMMARY
On January 30, 1981, representatives of the NRC staff met with Cortustion Engineering personnel and members of their owners group to discuss the technical scope and submittal schedule of emergency procedure guidelines required by TMI Action Plan I+em 1.C.1, and originally scheduled for submittal on or befom January 1981. Cortustion Engineering stated they could not meet this schedule, and requested the meeting to provide the staff with their proposed submittal schedule, as well as some details of the methodology they are using in the program. The detailed accident and transient guidelines called for in TMI action item 1.C.1 are to consider multiple and consequential failures of equipment as well as possible operator errors. CE explained that the guidelines presently being developed were derived from interim guidelines previously submitted to the staff in CEN 128 in respense to NUREG-0578 requirements. The representatives from CE began the meeting with a chronology and background on the CEN 128 work, indicating that they felt it has resulted in a significant improvement over earlier procedures, and is currently being utilized in plant training programs. Ilowever, significant uodifications to the current guidelines are still considered by CE as necessary to; enhance diagnostic capability, assist operator response, and cover contingencies. CE discussed their approach to develop the new guidelines. They are currently performing a systematic evaluation of a limited set of event initiators, in an attempt to identify limiting or bounding initiator events which can be used to generate the symptom-activated lead-in for the new guidelines. There was < concern among the staff that this limited set of events would not be comprehensive enough. Currently the only event initiators being addressed by the CE study am: loss of nomal feedwater; 8441lWVE5
.. excess feedwater loss of normal AC power steamline break, outside containment steam generator tube rupture sr.all RCS p!pe break, inside containment. The staff informed CE that they would review the selected events when submitted, and would determine if all credible initiator events had been considered. The basic methodology for conducting the event analysis was also discussed. It includes fault tree analyses, definition of sets of failures which threaten safety functions and evaluation of probability for each set. Event tree analyses are being used to evaluate probabilities of event failure combinations, and assess consequences of failure combinations that fall within probability cutoffs. Sequence of events diagrans are also being used to identify safety ' functions required, identify manual and automatic actions, and identify alternative success paths. CE indicated that workshop sessions are being held with personnel from utilities with CE designed reactors to help identify credible event sequences and potential equipment failures. Combustion presented a draft schedule for submittal of guidelines (Attachment #3). Dr. Hanauer of the staff expressed concern over this schedule, indicating that it might result in difficulties meeting the review schedule for the next CE plants coming up for operating license review. Discussien did not resolve these concerns, and the issue remains open. The staff will take the proposed CL schedule for meeting the requirements of TMI action item 1.C.1 under consideration.
t 3- ' At the conclusion of the meeting, discussions were held regarding the interim emergency procedure guidelines being reviewed in support of the San Onofre operating license review. Problems with the ICC guideline were discussed and CE indicated modifications could not be accomplished in time to accommodate the San Onofre review. It was proposed by the staff that the San Onofre plant-specific ICC procedure be reviewed by the Reactor Systems Branch in lieu of vendor guidelines. The staff and Contustion have both agreed to this approach. CE also submitted final responses to staff questions on the interim guidelines for loss of Feedwater and
- c. team generator tube rupture events. This material will be reviewed by the staff as part of the San Onofre review.
The metting was adjourned at approximately 4:00PM. , ~.,
