SUBJECT:
UNIVERSITY OF UTAHREQUEST FOR ADDITIONAL INFORMATION REGARDING RENEWAL OF FACILITY OPERATING LICENSE AND POWER UPRATE APPLICATION (TAC NO. ME1599)
Dear Dr. Jevremovic:
The U.S. Nuclear Regulatory Commission (NRC) is continuing its review of your application for the license renewal and power uprate of Facility Operating License No. R-126 for the University of Utah TRIGA reactor, dated March 25, 2005, and superseded in its entirety by an updated safety analysis report, dated June 1, 2009 (a redacted version of the safety analysis report is available on the NRCs public Web site at www.nrc.gov under Agencywide Documents Access and Management System Accession No. ML092090027).
We require additional information and clarification on questions that have arisen during our review. Please provide responses to the enclosed request for additional information within 60 days after the date of this letter. In accordance with Title 10 of the Code of Federal Regulations Section 50.30(b), you must execute your response in a signed original document under oath or affirmation.
If you have any questions about this review, or if you need additional time to respond to this request, please contact me by telephone at 301-415-0893 or by e-mail at geoffrey.wertz@nrc.gov.
Sincerely,
/RA by Kathryn M. Brock/

ENCLOSURE OFFICE OF NUCLEAR REACTOR REGULATION REQUEST FOR ADDITIONAL INFORMATION REGARDING THE EMERGENCY PLAN FOR THE LICENSE RENEWAL AND POWER UPRATE APPLICATION FOR THE UNIVERSITY OF UTAH TRIGA REACTOR LICENSE NO. R-126; DOCKET NO. 50-407 The U.S. Nuclear Regulatory Commission (NRC) is continuing its review of the application for the license renewal and power uprate of Facility Operating License No. R-126 for the University of Utah TRIGA reactor (UUTR) as documented in the UUTR safety analysis report, dated June 1, 2009 (a redacted version of the safety analysis report is available on the NRCs public Web site at www.nrc.gov under Agencywide Documents Access and Management System (ADAMS) Accession No. ML092090027).
The NRC staff performed its review of the UUTR emergency plan (EP) in accordance with the guidance provided in NUREG-0849, Standard Review Plan for the Review and Evaluation of Emergency Plans for Research and Test Reactors, issued October 1983, and American National Standards Institute/American Nuclear Society (ANSI/ANS)-15.16-2008, Emergency Planning for Research Reactors. During this review, the NRC staff identified areas for which it needs additional information. Please provide responses to the following request for additional information:
- 1.
In accordance with Section 3.2 of ANSI/ANS-15.16-2008, the definition of site boundary is unique to each reactor facility. The description of the site boundary provided in Section 2.0 of the UUTR EP lacks a physical description. Please provide the physical description of the site boundary.
- 2.
Section 3.5 of ANSI/ANS-15.16-2008 states, Action levels should be established in terms of effluent monitors or other plant parameters from which the dose rates and radiological effluent releases at the site boundary can be projected. In Section 4.2 of the UUTR EP, Emergency Action Level 1 states, Radiological effluents from the Reactor Laboratory (1205E, 1205F, 1205G Merrill Engineering Building) exceed 10 MPC when averaged over 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or 15 mrem whole-body dose equivalent accumulated in 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
2.1 How and where are these values measured, calculated, and displayed?
2.2 Are any alarms associated with these measures, and how do they relate to the emergency action levels?
2.3 What is the timeliness for the assessment of this action level with respect to emergency class declaration?
- 3.
Table 1, Emergency Action Levels for Classification of a Notification of Unusual Event, of ANSI/ANS-15.16-2008 describes the following action level characteristics that are not in Section 4.2 of the UUTR EP:
The UUTR EP has no action level for severe natural phenomena.
The UUTR EPs action level response with respect to bomb threats is narrower than that described in Table 1.
The UUTR EP has no action level for a credible security threat.
The UUTR EP action level response with respect to a fire does not reflect the guidance in Table 1.
Please justify the differences or revise accordingly.
- 4.
The Alert section of Table 1 of ANSI/ANS-15.16-2008 indicates that offsite authorities are provided with status information. Section 7.4 of the UUTR EP does not indicate any timeframe for notifications to the NRC and other offsite authorities in order to provide current status information. Please provide the timeframe for notifications to the NRC and offsite authorities.
- 5.
The Alert section of Table 1 of ANSI/ANS-15.16-2008 indicates that offsite authorities are provided with status information. Section 7.4 of the UUTR EP does not indicate whether a procedure controls the transmission of offsite information. Does the UUTR have a procedure that provides current status information to the NRC? Additionally, does it describe the contents of initial and follow-up messages to the NRC, including the emergency class, description of the event, and characterization of the release?
- 6.
Section 3.7.4(1) of ANSI/ANS-15.16-2008 indicates that the EP shall include an alternate assembly area. Section 7.6.3 of the UUTR EP did not indicate an alternate assembly area. Has an alternate assembly area been identified? If so, where is this information provided?
- 7.
Section 3.10.3 of ANSI/ANS-15.16-2008 indicates that the EP shall describe the provisions to ensure the operational readiness of emergency equipment and supplies.
The Emergency Equipment appendix to the UUTR EP does not list the frequency for any functional checks performed on the emergency equipment listed in the appendix.
Please provide the frequency for functional checks on emergency equipment.
- 8.
Please ensure that the recommendations previously agreed upon with the NRC staff and documented in the NRC letter to UUTR, dated February 17, 2005 (ADAMS Accession No. ML050470227) are implemented into the UUTR EP.
- 9.
Provide a copy of the UUTR EP revision to the NRC following the resolution of this request for additional information.
