RSO Radioactive Waste Management 2

Question 1

Liquid scintillation waste containing H-3 or C-14 may be disposed of by sanitary sewer only if:

Accepted Answer

The activity per liter and total monthly/annual discharge limits in the NRC license are not exceeded

Answer

NRC 10 CFR 20.2003 and license conditions specify allowable concentrations and total annual discharge quantities for sewer disposal; both the concentration and total limits must be met.

Question 2

A radioactive waste manifest (shipping paper) for LLRW transport must include all of the following EXCEPT:

Accepted Answer

Worker's personal dosimetry history

Answer

Waste manifests must document the generator, waste characteristics, radionuclides, and classification, but individual worker dosimetry records are not required on shipping manifests.

Question 3

Generators of LLRW must keep records of radioactive waste shipments for a minimum of:

Accepted Answer

3 years

Answer

NRC regulations require generators to retain records of radioactive waste shipments, including manifests, for at least 3 years, though many states require longer retention periods.

Question 4

Which of the following is the correct hierarchy for radioactive waste management, from most to least preferred?

Accepted Answer

Minimize generation → Reuse/recycle → Treat → Dispose

Answer

The preferred waste management hierarchy is to minimize waste generation first, then reuse or recycle materials, then treat to reduce hazard, and finally dispose as a last resort.

Question 5

Greater-than-Class-C (GTCC) LLRW differs from Class C in that it:

Accepted Answer

Cannot be disposed of in near-surface facilities and requires deep geological disposal

Answer

GTCC waste exceeds Class C concentration limits and cannot be safely disposed of in near-surface facilities, requiring deep geological disposal like HLW.
