MURR 45-Day and 120-Day Relicensing RAIs Mr. Geoffrey Wertz, This email is a follow up to our telephone conversation that occurred on Monday, January 23rd, regarding our efforts towards completing the remaining relicensing RAIs. We are formally requesting an extension of three months, to April 13, 2012.

After our January 6th submittal, which provided responses to four (4) RAIs and an updated version of the Technical Specifications, the following six (6) 45-Day Response and Complex questions still remain unanswered: 4.7, 6.2, 13.4.b, 13.7, C.1 and C.3. We are currently working with the College of Engineering to answer question 4.7. The remainder of the listed questions involve RELAP work, which includes benchmarking the model and revalidating our valve timing assumptions in the loss of low and coolant accidents. The individual that has been working on the RELAP questions just recently retired, but has been rehired part-time at 20 hours2.314815e-4 days <br />0.00556 hours <br />3.306878e-5 weeks <br />7.61e-6 months <br /> per week. His primary focus in the next few months will be the RELAP-related questions.

Additionally, based on the Safety Limit Amendment that was submitted to the NRC on August 24, 2011, a significant portion of Chapter 4, specifically Sections 4.5 and 4.6, still need to be revised and resubmitted.

Thank you in advance for your consideration and please let me know if you have any questions.
