II. Discussion The NRC has identified a potential generic issue associated with electrical equipment containing component made of aluminum. If the identified equipment were to experience a HEAF the presence of aluminum may cause greater damage to structures, systems, and components than previous analyses indicated. This generic issue has met all seven screening criteria of the generic issues program and is currently in the assessment phase (ADAMS Accession No. ML16349A027). To better understand the impact of aluminum, the NRC is sponsoring large- and smallscale testing. The large-scale testing will be undertaken as part of an international effort and the draft test plan for that program is publicly available (ADAMS Accession No. ML17201Q551). The purpose of this draft test program is characterize aluminum particle size distribution, rates of production and morphology (agglomeration) of HEAFs involving aluminum conductors. The measurements from these experiments will be used to support development of a HEAF/Aluminum combustion energy balance model to better characterize the aluminum HEAF hazard. This modeling effort will support advancements to quantify hazards HEAF pose to nuclear power plant risk. The small-scale testing is expected to be performed prior to any full-scale testing. The results from the small-scale work is expected to help inform to the large-scale test results and to support evaluation of the numerical method predictive capability. Model development is outside the scope of this test plan and is expected to be completed by a third party. This draft test plan has been developed by Sandia National Laboratories. The NRC is seeking public comment in order to receive feedback from the widest range of interested parties and to ensure that all information relevant to E:\FR\FM\05MRN1.SGM 05MRN1 Federal Register / Vol. 83, No. 43 / Monday, March 5, 2018 / Notices developing this document is available to the NRC staff. This document is issued for comment only and is not intended for interim use. The NRC will review public comments received on the documents, incorporate suggested changes as necessary, and make the final test plan available.

II. Description of the Proposed Rule Change 4 OCC uses quantitative methods to make estimates, forecasts, and projections.5 Specifically, OCC employs such methods in the context of its credit risk models, margin system and related models, and liquidity risk models.6 OCC refers to the use of such quantitative methods in this context as Risk Models.7 OCC’s use of models inherently exposes OCC to model risk.8 Such risk includes the consequences of decisions based on incorrect or misused model outputs.9 The proposed MRM Policy will apply to all Risk Models that OCC uses to determine, quantify, or measure actual or potential risk exposures or risk mitigating actions.10 The MRM Policy details the general framework for OCC’s model risk management practices, including describing and outlining the roles and responsibilities of OCC’s Quantitative Risk Management department (‘‘QRM’’), Model Validation Group (‘‘MVG’’), and Model Risk Working Group (‘‘MRWG’’).11 The MRM Policy also addresses the roles of OCC’s Legal department, Management Committee (‘‘MC’’) and Board Risk Committee (‘‘RC’’) in the review and approval of OCC’s Risk Models.12 The proposed rule change would formalize and update OCC’s MRM Policy. Under the MRM Policy, QRM will be responsible for developing, implementing, and monitoring OCC’s Risk Models.13 Regarding model development, QRM will maintain documentation of the design, theory, and logic of each Risk Model, including a description of the model, its intended purpose, assumptions, supporting data, limitations, and other details.14 As part of model implementation, QRM will review, evaluate, and propose model changes, including model decommissioning, make recommendations to the MRWG for approval of changes, and seek review by the Legal department regarding the regulatory filing requirements related to 4 All terms with initial capitalization that are not otherwise defined herein have the same meaning as set forth in the OCC By-Laws and Rules. 5 Notice, 83 FR at 2271, n. 6. 6 Id. 7 Id. 8 Notice, 83 FR at 2271. 9 Notice, 83 FR at 2271, n. 5. 10 Notice, 83 FR at 2271. 11 Id. 12 Notice, 83 FR at 2272. 13 Notice, 83 FR at 2272–73. 14 Notice, 83 FR at 2272.
