NRRPT Radioactive Waste Management & Disposal 3

Question 1

Under 10 CFR Part 20, what is required before a licensee can release solid materials from a licensed facility?

Accepted Answer

Survey to demonstrate dose to the average member of the critical group does not exceed 1 mrem/yr

Answer

10 CFR 20.2002 and NRC guidance establish that solid materials may be released if they meet a 1 mrem/yr dose criterion to the average member of the critical group, determined by survey and dose modeling.

Question 2

What is the primary purpose of a Radioactive Material License condition requiring a waste minimization program?

Accepted Answer

To reduce the volume and activity of radioactive waste generated, lowering disposal costs and doses

Answer

Waste minimization programs reduce generated waste volume and activity, which lowers disposal costs, occupational doses during handling, and long-term environmental liability.

Question 3

Which Department of Transportation (DOT) regulation primarily governs the transportation of radioactive materials?

Accepted Answer

49 CFR Part 173 Subpart I

Answer

49 CFR Part 173 Subpart I establishes DOT requirements for packaging, labeling, marking, and placarding of radioactive materials during transportation.

Question 4

A radioactive waste shipment requires a 'Type B' package when:

Accepted Answer

The activity exceeds Type A quantity limits for the specific radionuclide

Answer

Type B packaging is required when the radioactive material content exceeds the Type A quantity limits specified in 49 CFR 173.431, ensuring containment under accident conditions.

Question 5

What is the purpose of a waste manifest (Uniform Low-Level Radioactive Waste Manifest) when shipping LLW?

Accepted Answer

To document waste identity, quantity, origin, and chain of custody from generator to disposal facility

Answer

The Uniform LLW Manifest (NRC Form 540/541/542) tracks waste from point of generation through transportation to disposal, ensuring accountability and regulatory compliance.
