- GE LTRs will not be used as the basis for fuel related analyses
- Fuel dependent safety analysis basis and applicability of the methods for EPU conditions provided for the analyses 23 or-~
roach for Fuel Dependent Anal ses In the Safety Analysis Report
- Several EPU, NRC and Framatome methodology meetings Limiting events for EPU conditions determined by Framatome through evaluation of FSAR events
- Evaluation of transients performed 24
Approach for Fuel Dependent Analy'es j
In the Safety Analysis Reporit Safety analysis events:
- Generator Load Rejection with Bypass Failure
- Recirculation Flow Run-up
- Loss of Feedwater Heating
- Single-Feedwater Pump Trip
- Loss of All FW flow
- Over Pressurization
- Loss of Coolant Accident
- Control Rod Drop Accident

- Current Status of LTT Exemption Justification Work in Progress/Best Estimates of Conclusions o Exemptions will be Technically Justified o Current Rationale Includes:
- Events are well documented
- EPU profiles are comparable
- Gains do not justify the risks
- Advanced analytical methods are applicable to EPU conditions
- Other Discussion Topics
- Two-step uprate o
Full complement of tests for first step o
Full complement of tests after second step o
Full Power is defined as 95% to 100%
RFP trip or condensate pump trip may cause Unit trip under some conditions o
FW flow margin about 7% after first step increase (10% today) o Parametric studies being performed by NSSS Vendor o
MELLLA+ operation makes these transients more susceptible to Unit trip o Administrative limits on low water level may result in a pre-emptive trip
- Steam Dryer Performance and Structural Testing o
Stepped approach to power ascension o Moisture carryover and acoustic loading criteria included in acceptance criteria
SUMMARY
- Testing per CLTR Test Program
- Testing Attachment will Supply Justification for LTT Exemptions
- Testing Attachment will Demonstrate Compliance with SRP 14.2.1
- Testing Exemptions will be Technically Justified
