OFFICE OF NUCLEAR REACTOR REGULATION REQUEST FOR ADDITIONAL INFORMATION REGARDING LICENSE RENEWAL REQUEST FOR THE UNIVERSITY OF TEXAS AT AUSTIN TRIGA MARK II NUCLEAR REACTOR LICENSE NO. R-129; DOCKET NO. 50-602 The U.S. Nuclear Regulatory Commission (NRC) is continuing its review of your application for renewal of Facility Operating License No. R-129, for the Nuclear Engineering Teaching Laboratory (NETL) TRIGA Mark II Nuclear Research Reactor (the facility) owned by the University of Texas at Austin (UT, the licensee), dated December 12, 2011, as most recently supplemented on July 15, 2015 (available on the NRCs public website, www.nrc.gov, in the Agencywide Documents Access and Management System (ADAMS), Accession Nos.
ML12156A097 and ML15211A638).
During the review of your recent submittal for license renewal of the NETL TRIGA Mark II Nuclear Research Reactor (herein referred to as UT TRIGA), the following question has arisen for which we require additional information.
The guidance in NUREG-1537 Section 4.5.2, Reactor Core Physics Parameters, requests the applicant provide calculations of certain core physics parameters and compare them with applicable measurements. A request for additional information was sent to you in a letter dated July 25, 2012 (ADAMS Accession No. ML15211A638), regarding a comparison of calculated and measured values for reactivity parameters. In response, your submittal dated July 15, 2015 (ADAMS Accession No. ML121500308), provided calculations for control rod worth and excess reactivity in Tables 11 and 12, respectively. In addition, you provided comparisons of these calculations and measurements in Table 13.
- a. In Table 11, your calculations of excess reactivity and control rod worth on 3/16/1992, 7/24/2007, 6/4/2008, 6/11/2008, 6/14/2010, 6/23/2010, 7/25/2011, and 8/2/2012 indicate the shutdown margin for the UT TRIGA reactor would have a positive reactivity. A positive reactivity would not meet Technical Specification 3.2 Shutdown Margin. Please justify why the positive reactivity presents an acceptable level of safety regarding shutdown margin for the UT reactor.
- b. In Tables 11 and 12, your calculations for excess reactivity are consistently higher than the measured values. The average bias between the calculated and measured values is
$2.56. Please justify why this bias presents an acceptable level of agreement in modeling the UT reactor.
- c. Control rod worth in Table 13 appears to be inconsistent. For example, the Regulating Rod worth varies between +12.7% and -21.2%. Specifically, the values for two separate Regulating Rod data points on 7/13/2012, changes from -10.1% to +12.7%. Similarly, Shim-2 worth varies between -23.1% and +30.1%. Please justify why these variations indicate an acceptable level of agreement in modeling the UT reactor.
