Enterpy VY Action Items from June 30. 2005 NRC Meeting on GE Methods o Provide a discussion of the fuel safety parameters of interest including rationale for inclusion and phenomena covered. Include a discussion of the reason why additional restriction/margin is/is not necessary for the following:

o MCPR (SLMCPR and OLMCPR) o LHGR o MAPLHGR o SDM o Stability o Exposure o Supersede the response to Reactor Systems Branch RAI #6 o Additional information will be provided on the following:

o CASMO Simulate

• How it is used

• Data for core follow

• Validation data

• Void fraction applicability o Neutron Monitoring System Noise from void creation high in core.

o Cold Critical Data from the BWR Fleet

• Focus on cold critical data from plants with similar void fraction

• Data for mid-cycle cold startups o Isotopics - Provide relevant aspects of the GE procedure for core burn evaluation o Specific discussion on ODYN conservatism versus TRACG o VY Steady State data on LHGR performance o Accuracy of TIP system

• Progress from TIP measurements to pin power

• Monte Carlo N-Particle (MCNP) transport code runs o Conservatisms provided by SAFER (MAPLHGR) o VY reactivity anomaly Tech Spec and surveillance results, include Plant

'E' Cycle 10 discussion.

o Void reactivity effect for transients o Plant operational context (successful operation with greater than 70%

void fraction)
