Source Remove: Sealed Source Recovery and Disposal Initiatives § ORS/Off-Site Source Recovery Project (OSRP) o Administered by the Los Alamos National Laboratory (LANL) and Idaho National Laboratory (INL) o Recovery and disposition of high activity disused sources in the interest of national security, public health, and safety o Source recovery prioritization – threat reduction methodology developed in coordination with the NRC Registration of sources for both SCATR & OSRP located at: http: //osrp. lanl. gov/Pick. Up. Sources. aspx 5
Source Remove: Sealed Source Recovery and Disposal Initiatives § CRCPD Source Collection and Threat Reduction (SCATR) Program o Technical assistance and cost-share support to licensees for commercial disposal of sealed sources o Funded by DOE/NNSA and administered by the Conference of Radiation Control Program Directors (CRCPD) Registration of sources for both SCATR & OSRP located at: http: //osrp. lanl. gov/Pick. Up. Sources. aspx 6
Commercial Sealed Source Disposal § Commercial Class A, B, an C sealed source disposal access now widely available: o US Ecology in Washington (generators in 14 States); Nationwide access to WCS in Texas § NRC updated disposal guidance: Concentration Averaging and Encapsulation Branch Technical Position (CA BTP) o Increased “generic” source disposal limits (but still below the NRC Class limits) o “Alternative Approach” provisions potentially enable disposal of most Class A, B, C sealed sources up to their NRC Class limits o Clarification regarding disposal of high-activity Co-60 as Class B waste § Increased availability of Type B transport containers 7
The CA BTP and the SCATR Irradiator Disposal Pilot § The 2015 revisions update and clarify sealed source disposal limits o Cs-137 ‘generic‘ Class C limit increased from 30 Ci to 130 Ci o Co-60 sources addressed explicitly – no Class B/C limit o ‘Alternative approach’ justifications only needed for Cs-137 sources between 130 Ci and the ~957 Ci Class C limit § 2017 SCATR disposal at US Ecology: o MDS Nordion/Gammacell 1000 irradiator, manufactured in 1986 o Two special form source capsules w/current activity of ~560 Ci o US Ecology Disposal/WA DOH approval (roughly half the cost of WCS) o Justification based disposal configuration and facility features common to shielded devices and to disposal US Ecology and WCS 8
Radioactive Source Removal – New Containers Off-Site Source Recovery Project removes & disposes of disused sources in the U. S. 435 -B 380 -B USA/9355/B(U)-96 More easily transport shielded Cs-137 and Co-60 devices • Transport by truck, rail, ship, air • External dimensions 2. 11 m H x 1. 78 m OD • Empty weight 4, 940 lbs, total weight 10, 100 lbs USA/9370/B(U)-96 Able to transport unique sources including Co, Cs, Sr, Ir, Ra, Am, Pu and Depleted Uranium • Transport by truck, rail, ship, air • External dimensions 3. 00 m H x 2. 54 m OD • Empty weight 55, 000 lbs, maximum ~67, 000 lbs • Will be delivered Fall 2019 9
Remaining Challenges § Greater-than-Class C (GTCC) commercial disposal not yet available o NRC draft regulatory basis review underway § Impact of the 2015 NRC BTP sealed source provisions remains uncertain: o Limited use to date of the “Alternative Approaches” for disposal of high-activity Class B/C sources o Alternative approach pilots o Commercial disposal of sources is a significant expense for generators relative to storage § Disposal of foreign origin transuranic sources remains problematic 10
Foreign Origin Americium: The Problem § Am-241 sealed sources are commonly used industrial applications o Well-logging, manufacturing and construction. § Currently ~7, 500 disused foreign origin Am-241 sources with no disposition pathway in the U. S. § This number is expected to grow to 20, 000 by 2025. 11
Foreign Origin Americium: The Problem § These sources cannot be disposed of because: o The Waste Isolation Pilot Plant (WIPP) Land Withdrawal Act only allows for disposal of waste materials generated by atomic energy defense activities. o The foreign-origin sources have the same properties as the domestic Am-241 being disposed at WIPP, but are ineligible for disposal. § The lack of a current disposal option for this waste presents a significant challenge. 12
Cesium Irradiator Replacement Project (CIRP) • Removal of disused Cs-137 • Incentives for replacement with X-ray • Consistent throughput • Permanent risk and cost reduction 13
Congressional Support for Permanent Risk Reduction § The FY 19 National Defense Authorization Act sets the goal of eliminating cesium blood irradiators in the US by the end of 2027. § This is a voluntary effort for owners of blood irradiation devices. § Our ability to meet the 2027 goal is dependent on continued funding and volunteers. § The Authorization Act supports the established CIRP incentive structure and process 14
Cesium Irradiator Replacement Project (CIRP) Projections § To meet the NDAA metric, NNSA ORS is targeting ~70 replacements per year o The program currently has participant comments to facilitate ~70 replacements per year for the next couple of years o To date, over 160 Cs-137 and Co-60 blood and research irradiators have been replaced, or are slated for replacement, with x-ray devices; § University of California System replacement initiative: o In 2017 -18, the research/medical staff agreed to assess the feasibility of replacement o As a result, about ~40 of 44 Cs-137 blood and research irradiators will likely be replaced with x-ray devices § New York City: ORS has received commitments to replace approximately 75% of NYC licensed gamma irradiators, including 100% of the blood irradiation devices. 15
