Answer to Question #4813 Submitted to "Ask the Experts"

Category: Decommissioning — Decommissioning and Decontamination Operations

The following question was answered by an expert in the appropriate field:

At our university the board of directors is concerned about the financial liability of future decommissioning of accelerators. I am wondering if there are schemes (in the United States for instance) that propose certain amounts of money to be reserved for future decommissioning of certain types of accelerators. I know of the 10 CFR 35 regulations for licensees of radioactive materials, but that does not apply to accelerators.

In the United States, accelerators are regulated by state governments (not the federal government)—e.g., the U.S. Nuclear Regulatory Commission has no oversight responsibility. The state of Illinois, for example, requires financial assurance for particle accelerators that manufacture radionuclides for distribution to other licensees or customers. In fact, the state of Illinois has prepared a Guidance Document on Financial Assurance (Revision 1; June 2000) that provides excellent guidance on how to determine financial assurance amounts.
