Division of Spent Fuel Management, NMSSU.S. Nuclear Regulatory CommissionPublic Meeting with Holtec InternationalJune 19, 2018Holtec HI-STORE CIS Review

-Discussion of 5/24/18 RAI responses on Aircraft Hazards Summary*March 28, 2018

-NRC issues request for additional information (RAI), Part 1

-RAI 2-1 -Requests additional details on aircraft hazards assessment for HI

-STORE CISF site

• May 24, 2018

-Holtec submits responses to RAIs

• NRC staff has identified issues in Holtec's response to the aircraft hazards analysis

-Proximity criteria for flight paths (NUREG

-0800)-Effective area for the facility

-Crash rate for military aircraft

-Units of measurement (statute vs. nautical)

-Descriptions of SAR Figures Issue 1 -Proximity Criteria fromNUREG-0800*Criterion B from Section 3.5.1.6 of NUREG

-0800 not met

-Proximity of military flight path to the facility requires detailed analysis*Additional information required for detailed analysis

-Annual number of flights, crash rates for specific aircraft types, distance to site, effective area of facility needed to estimate cumulative annual crash probability Issue 2 -Estimate of effective area of the facility

• Section 3.5.1.6, Subsection 7 of NUREG

-0800 provides guidance for estimating effective area of facility

-Must include footprint area of facility, skid area for specific aircraft, and shadow area of facility structures

• Response does not include shadow area or skid area

-Only footprint area for facility is included Issue 3 -Basis for military aircraft crash rate

• Response does not provide basis provided for assumed military aircraft crash rate

• Section 3.5.1.6, Subsection 2 of NUREG

-0800 cites specific references with data on aircraft crash rates

-DOE, "Accident Analysis of Aircraft into Hazardous Facilities," DOE-STD-3014-96, October 1996 Issue 4 -Units of measurement for airway distances

• RAI response should use consistent distance measurement units

-SAR Table 2.2.5 cites distances in nautical miles, compares with statute miles from FAA Sectional chart

• Analysis should consider distances to edge of airway Issue 5 -References to SAR Figure 2.2.7

• RAI response does not provide specific explanations of the information in SAR Figure 2.2.7

-Any figures, tables, or charts provided in the application should be adequately described Conclusions

• NRC staff needs additional information to address RAIs on aircraft hazards and determine compliance with NRC's safety regulations

• Timely completion of NRC review of Holtec's HI

-STORE CISF application requires complete and high quality responses to NRC staff's questions
