1
Management of Spent Nuclear Fuel By: Matthew R. MacDougall Nuclear Engineer of Oregon State University Sponsored by American Nuclear Society August 1 st, 2012
2
Overview Background Policies to date Applications Recommendations
3
Issue Definition Decrease dependence of fossil fuels 1 fuel pellet equals… Bad part: produces spent nuclear fuel
4
Types of Waste Low level Transuranic (medium) High level
5
Spent Nuclear Fuel Product of the Fission Process Contains 2 main types of isotopes ◦Actinides (Pu-240, U-238, Th-232) ◦Fission Products (Tc-99, I-129, Cs-137)
6
SNF Storage Methods Fuel Flow Chart New Fuel Final Repository Temporary On Site Storage Interim Storage Site Reprocess Reactor
7
Governmental Policies To Date Nuclear Waste Policy Act (1982) Nuclear Waste Policy Act Amendment (1987) ◦Both need amending to legally pursue a new storage method Recommendations ◦Blue Ribbon Commission Appointed by DOE 8 recommendations on SNF management
8
Overseeing Groups 3 Main Agencies Dictated by NWPA ◦Department of Energy (DOE) ◦Nuclear Regulatory Commission (NRC) ◦Environmental Protection Agency (EPA)
9
Interests And Values At Stake Nuclear Waste Fund Safety Not In My Backyard (NIMBY) Consent from state
10
Policy Alternatives On-Site Storage Dry cask storage Minimal transportation Using reactor security Small space available
11
Policy Alternatives Interim Consolidated Storage One of the recommendations by BRC ‘Staging Area’ Consolidate waste - safer Takes some pressure off DOE Transportation still an issue Needs self security and construction
12
Transporting Issues Biggest convenience of on-site storage (lack of transportation) No spills thus far Tests ◦Fuel Cask TestingFuel Cask Testing Terrorism ◦Blow up casks ◦Stealing Self-protecting
13
Policy Alternatives Long-Term Storage Very confusing ◦Lots of policies up in the air Closing of YM
14
Waste Isolation Pilot Program Carlsbad, New Mexico Storage of Transuranic Waste Example of successful storage ◦Very different than HLW though Environmental Evaluation Group (EEG) ◦Way of promoting consent
15
Recommendations SNF ◦Increasing issue ◦Can’t keep on putting it off ◦Repository necessary Interim storage ◦Safe, consolidated storage ◦Transportation very safe Long time to construct implement, need to start now!
