FERMI 2 - REQUEST FOR ADDITIONAL INFORMATION - PRR-002 (ME2548),

AND PRR-003 (ME2549) - Application dated 11/3/10 (ML093140302)

In reference to your above application, please arrange a teleconference to discuss the following information with the NRC staff.

For Relief Request PRR-002 (Parallel Testing of Core Spray Pumps):

1. Will Group A type testing be performed at nominally full flow conditions of greater than or equal to 6,600 gpm per division?
2. Why are the monitoring, analysis, and evaluation requirements of ISTB-6000 limited to Alert and Action Range low criteria only (i.e., Alert and Action Range high criteria are not included)?
3. The relief request states that when a reference curve may have been affected by repair, replacement, or routine servicing of a pump, a new reference curve will be determined, or an existing reference curve will be reconfirmed. Is relief therefore being sought from ISTB-3310?
4. Will the vibration acceptance criteria of Table ISTB-5121-1 still apply and be applied to each pump individually. Will a single value be used over the whole range of the pump curve?
5. The relief request states that the first Comprehensive Pump Test (CPT) will be performed on each of the Core Spray pumps no later than February 17, 2013. When will the second CPT be performed?

For Relief Request PRR-003 (EECW Pump Testing with Pump Curves):

1. Will testing will be done at substantial flowrates of greater than or equal to 1,550 gpm?
2. Will the vibration acceptance criteria of Table ISTB-5121-1 still apply? Will a single value be used over the whole range of the pump curve?
3. Does this relief request apply also to the Comprehensive Pump Test (CPT) required by OM Code, or just the Group A test?
