OFFICE OF NUCLEAR REACTOR REGULATION REQUEST FOR ADDITIONAL INFORMATION UNIVERSITY OF WISCONSIN FACILITY OPERTING LICENSE NO. R-74 DOCKET NO. 50-156 The U. S. Nuclear Regulatory Commission (NRC) staff is continuing the review of your application for renewal of Facility Operating License No. R-74, dated May 9, 2000, as supplemented by letters dated October 17, 2008; June 16, 2010 (two letters); July 8, 2010, and August 11, 2010. During our review of the proposed University of Wisconsin Nuclear Reactor (UWNR) technical specifications (TSs), questions have arisen for which we need additional information and clarification. Please address and provide the requested information to the following:

1. Proposed UWNR TS 3.3 contains limits on primary water conductivity but does not contain a limit on pH. NUREG-1537, Chapter 5, Reactor Coolant Systems, Section 5.2, Primary Coolant System, requests applicants to provide coolant quality requirements, including pH. Please explain why a limit on pH is not necessary to limit corrosion of fuel cladding and other materials in the reactor pool; or propose and justify a limit on pH.
2. Proposed UWNR TS 3.2.5 does not contain an interlock to prevent the withdrawal of multiple control elements at the same time. NUREG-1537, Chapter 13, Accident Analysis, Section 13.1.2, Insertion of Excess Reactivity, requests applicants to analyze ramp insertions of reactivity. Please analyze and discuss a reactivity addition event based on the withdrawal of the maximum number of control elements possible in accordance with your TSs. Please discuss the results of the analysis as compared against the safety limit for the reactor.
