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

Written approval from the state radiation control program

Answer

Documentation that all radioactivity has decayed to background

Answer

Approval from the Environmental Protection Agency

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

To reduce the number of radiation workers needed at a facility

Answer

To comply with EPA air emission regulations

Answer

To satisfy DOT packaging requirements for waste shipment

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 170

Answer

10 CFR Part 71

Answer

40 CFR Part 262

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

The waste volume exceeds 55 gallons

Answer

The dose rate at the package surface exceeds 200 mrem/hr

Answer

The waste is classified as Class C LLW

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

To authorize the generator to produce radioactive waste

Answer

To certify that workers handling the waste have received training

Answer

To request an exemption from DOT shipping requirements

Question 6

The ALARA principle as applied to radioactive waste management means:

Accepted Answer

Waste generation, worker doses during handling, and public doses should be minimized as reasonably achievable

Answer

All waste must be disposed of within 1 year of generation

Answer

Activity levels must be reduced to zero before disposal

Answer

Only licensed personnel may handle any quantity of radioactive waste

Question 7

Which of the following best describes a 'Contact-Handled' (CH) TRU waste package versus a 'Remote-Handled' (RH) TRU waste package?

Accepted Answer

CH-TRU has surface dose rates ≤200 mrem/hr; RH-TRU has surface dose rates >200 mrem/hr

Answer

CH-TRU has higher alpha activity; RH-TRU has higher beta activity

Answer

CH-TRU requires robotic handling; RH-TRU can be handled manually

Answer

CH-TRU is liquid waste; RH-TRU is solidified waste
