April 5, 2016 MEMORANDUM TO: Brian E. Thomas, Director Division of Engineering Office of Nuclear Regulatory Research FROM: Joseph G. Giitter, Director /RA/ Division of Risk Assessment Office of Nuclear Reactor Regulation SUBJECT: RESULTS OF PERIODIC REVIEW OF REGULATORY GUIDE 1.98 This memorandum documents the U.S. Nuclear Regulatory Commission’s (NRC) periodic review of Regulatory Guide (RG) 1.98, “Assumptions Used for Evaluating the Potential Radiological Consequences of a Radioactive Offgas System Failure in a Boiling Water Reactor,” published in March 1976. The RG describes methods that the NRC staff considers acceptable for complying with the NRC’s regulations regarding the evaluation of the potential radiological consequences of a boiling-water reactor radioactive gas storage tank failure. As discussed in Management Directive 6.6, “Regulatory Guides,” the NRC staff reviews RGs approximately every 5 years to ensure that the RGs continue to provide useful guidance. Documentation of the Office of Nuclear Reactor Regulation (NRR) staff review is enclosed. Based on the results of the periodic review, the NRR staff concludes that no changes to RG 1.98, are warranted at this time. However, the staff identified issues in the review that could warrant addressing in a future revision. These issues are primarily the result of the NRC publishing updated guidance that is applicable to this area, but is located in other documents (i.e., other RGs and NUREGs), as described in detail in the enclosed review.
