NRC SEEKS COMMENT, PLANS PUBLIC MEETINGS 

ON BLENDING OF LOW-LEVEL RADIOACTIVE WASTE 

 The Nuclear Regulatory Commission is seeking public comment on issues associated 

with blending of low-level radioactive waste and is planning public meetings to discuss blending 

in Rockville, Md. 

 The issue of blending low-level radioactive waste has received increased attention from 

the nuclear industry since the 2008 closing of the Barnwell, S.C., low-level waste disposal site. 

This action left waste generators in 36 states with no disposal options for Class B and Class C 

wastes, the two classes of low-level waste with higher radioactivity. Blending in some cases can 

lower the classification of the wastes to the lower-radioactivity Class A, which has available 

disposal capacity, by reducing the concentration of radionuclides. 

 Blending refers to mixing low-level wastes of different concentrations, primarily Class B 

or C with Class A. It does not involve mixing radioactive waste with non-radioactive waste, a 

practice known as “dilution.” And it does not imply release of radioactive material to the general 

environment, either to municipal non-radioactive waste disposal sites or to consumer products. 

Blended wastes remain low-level waste and must be disposed in a licensed low-level waste 

disposal facility. 

 Blending is not prohibited or expressly addressed in NRC regulations. NRC staff 

guidance discourages blending in some circumstances, but also recognizes that blending – 

including blending that lowers the classification of a waste – may be appropriate in others. 

 NRC Chairman Gregory B. Jaczko directed the agency staff Oct. 8 to prepare a vote 

paper within six months for the Commission to consider issues related to blending of low-level 

radioactive wastes. Specific questions to be discussed at the upcoming public meeting are spelled 

out in a Federal Register notice published Nov. 30 seeking public comment. 

 A public meeting will be held Jan. 14 from 8 a.m. to 5:30 p.m. at the Legacy Hotel & 

Meeting Centre, 1775 Rockville Pike, Rockville, Md., to receive public comment on blending 

issues. In addition, NRC staff will meet separately with three companies that have expressed 

interest in blending in order to better understand their views. The staff will meet with Waste 

Control Specialists Dec. 14, from 9:00 a.m. to 12:30 p.m.; with Studsvik the same day from 1:30
