STATEMENT OF WORK

1. PROJECT TITLE

High Energy Arcing Faults (HEAFs) Phase 2.

2. BACKGROUND

High Energy Arcing Faults (HEAFs) have the potential to cause extensive damage to the failed electrical component and distribution system along with adjacent equipment and cables within the zone of influence. The significant energy released during a HEAF event can act as an ignition source to other components. By better understanding the HEAF event hazard through testing, the NRC can advance the state of knowledge and support developing a model to adequately evaluate this hazard in performance-based applications.

The current state-of-the-art evaluation of fire effects from a HEAF event is contained in NUREG/CR-6850 Appendix M and NFPA 805 Frequently Asked Question (FAQ) 35.

NUREG/CR-6850 contains a model to evaluate HEAFs in cabinets, and the National Fire Protection Association (NFPA) 805 FAQ 35 contains a HEAF model for bus ducts. Each of these models is based primarily on a single event that corresponds to the type of failure;

however, these models do not allow adjustments to account for variables that can influence hazards to adjacent critical equipment from a HEAF event. Further, these events continue to occur, with the most recent event in the U.S. occurring in March 2010 and producing two HEAFs. One of the HEAFs had a different failure mode from that characterized in NUREG/CR- 6850 or NFPA 805 FAQ. To support improvement in state-of-the-art fire Probabilistic Risk Assessment (PRA) modeling of HEAF events, the NRC needs additional test data. Additional test data will improve the state of knowledge and provide better characterization of HEAF in the fire PRA and NFPA 805 license amendment request applications.

Previously, a test program was conducted in 2013 and 2014 to obtain data to support model advancements and in cooperation with international partners. These test programs support the Organization for Economic Co-Operation and Development (OECD) Nuclear Energy Agency’s (NEA) “A Project to Characterize High Energy Arcing Fault Events.” As part of the international agreement, each participating country donated equipment to the NRC for testing. Subsequent to the testing performed in 2013/2014, additional equipment and needs for testing was identified.

By building upon previous tests, the NRC envisions that a second testing phase will provide more data that will help improve the understanding of the HEAF phenomena. This testing program should implement insights from previous tests to measure or monitor parameters that will allow for the widest applicability for enhancing fire PRA applications and analyses. For example, there are current models that estimate flash heat flux levels, by including flux gauge or other types of devices that can measure radiative heat flux. Further HEAF testing would provide an opportunity to compare such models or develop new ones, if so required.

12. RESEARCH QUALITY

The quality of NRC research programs are assessed each year by the Advisory Committee on Reactor Safeguards. Within the context of their reviews of RES programs, the definition of quality research is based upon several major characteristics:

Results meet the objectives (75% of overall score) Justification of major assumptions (12%) Soundness of technical approach and results (52%) Uncertainties and sensitivities addressed (11%)

Documentation of research results and methods is adequate (25% of overall score) Clarity of presentation (16%) Identification of major assumptions (9%)

It is the responsibility of the contractor to ensure that these quality criteria are adequately addressed throughout the course of the research that is performed. The NRC Contracting Officer’s Representative (COR) and technical monitor will review all research products with these criteria in mind.

13. PUBLICATIONS NOTE

RES encourages the publication of the scientific results from RES sponsored programs in referenced scientific and engineering journals as appropriate. If the laboratory proposes to publish in the literature or present the information at meetings, approval of the proposed article or presentation should be obtained from the NRC COR. The COR shall approve the material as submitted, approve it subject to the NRC’s suggested revisions, or disapprove it. In any event, the COR may disapprove or delay presentation or publication of papers on information that is subject to Commission approval that has not been ruled upon or which has been disapproved.

Additional information regarding the publication of NRC sponsored research is contained in NRC Management Directives 3.7, “NUREG Series Publications,” and 3.9, “NRC Staff and Contractor Speeches, Papers, and Journal Articles on Regulatory and Technical Subjects.”

NEW STANDARDS FOR CONTRACTORS WHO PREPARE NUREG-SERIES MANUSCRIPTS

The U.S. Nuclear Regulatory Commission (NRC) began to capture most of its official records electronically on January 1, 2000. The NRC will capture each final NUREG-series publication in its native application. Therefore, please submit your final manuscript that has been approved by your NRC COR in both electronic and camera-ready copy.

All format guidance, as specified in NUREG-0650, Revision 2, will remain the same with one exception. You will no longer be required to include the NUREG-series designator on the bottom of each page of the manuscript. The NRC will assign this designator when we send the camera-ready copy to the printer and will place the designator on the cover, title page, and spine. The designator for each report will no longer be assigned when the decision to prepare a publication is made. The NRC's Publishing Services Branch will inform the NRC COR for the publication of the assigned designator when the final manuscript is sent to the printer.

For the electronic manuscript, the Contractor shall prepare the text in Microsoft Word, and use any of the following file types for charts, spreadsheets, and the like.

File Types to be Used for NUREG-Series Publications

File Type File Extension

Microsoft®Word® .doc

Microsoft® PowerPoint® .ppt

Microsoft®Excel .xls

Microsoft®Access .mdb

Portable Document Format .pdf

This list is subject to change if new software packages come into common use at NRC or by our licensees or other stakeholders that participate in the electronic submission process. If a portion of your manuscript is from another source and you cannot obtain an acceptable electronic file type for this portion (e.g., an appendix from an old publication), the NRC can, if necessary, create a tagged image file format (file extension.tif) for that portion of your report.

Note that you should continue to submit original photographs, which will be scanned, since digitized photographs do not print well.

If you choose to publish a compact disk (CD) of your publication, place on the CD copies of the manuscript in both (1) a portable document format (PDF); (2) a Microsoft Word file format, and

(3) an Adobe Acrobat Reader, or, alternatively, print instructions for obtaining a free copy of Adobe Acrobat Reader on the back cover insert of the jewel box.
