Abstract
Implementations are described herein that include producing waste forms that include an amount of radioactive waste material encapsulated in an amount of polymeric material. The waste form can be produced by heating a mixture that includes the polymeric material and the radioactive waste material. The heated or molten mixture is then subject to a process that applies an amount of pressure to the heated mixture and produces the waste form.
Claims20
A method comprising:
- combining an amount of radioactive waste material with an amount of a polymeric material to produce a mixture;
- heating the mixture at temperatures above a glass transition temperature of the polymeric material and below a melting temperature of the polymeric material to produce a heated mixture;
- and
- applying an amount of pressure to the heated mixture to produce a waste form that includes the radioactive waste material encapsulated in the polymeric material.
