NRRPT Regulatory Compliance & Documentation 4 — Questions and Answers
Question 1: Under 10 CFR 20.2106, occupational dose records must be retained for:
- 5 years
- 10 years
- The lifetime of the individual, or 3 years after termination of the license, whichever is longer (Correct answer)
- Until the next NRC inspection
Correct answer: The lifetime of the individual, or 3 years after termination of the license, whichever is longer
10 CFR 20.2106 requires that individual monitoring records be retained until the NRC authorizes their disposal, effectively requiring lifetime retention.
Question 2: A 10 CFR 50.59 evaluation is required before a licensee can:
- Hire a new Radiation Safety Officer
- Make a change to a facility or procedures that may affect safety systems without prior NRC approval (Correct answer)
- Conduct routine quarterly ALARA reviews
- Submit an annual radiation protection program report
Correct answer: Make a change to a facility or procedures that may affect safety systems without prior NRC approval
10 CFR 50.59 requires licensees to evaluate proposed changes against specific criteria before implementing modifications that could affect the safety analysis.
Question 3: Under NRC regulations, a 'declared pregnant worker' must inform the licensee of her pregnancy in:
- Verbal form only
- Writing (Correct answer)
- Either written or verbal form at her discretion
- Writing countersigned by her physician
Correct answer: Writing
10 CFR 20.1208 specifies that the 'declaration of pregnancy' must be made voluntarily in writing to trigger the 0.5 rem gestational dose limit.
Question 4: The NRC's NUREG-1556 series provides guidance for license applications. NUREG-1556, Vol. 7 specifically addresses licenses for:
- Power reactors
- Industrial radiographers (Correct answer)
- Academic and research institutions
- Well logging operations
Correct answer: Industrial radiographers
NUREG-1556 Vol. 7 provides consolidated guidance for NRC licensees conducting industrial radiography under a specific materials license.
Question 5: When a licensee terminates a radioactive materials license, the NRC requires submission of a:
- Final ALARA report only
- Decommissioning funding plan
- License termination plan and radiological survey report confirming cleanup (Correct answer)
- Certificate of material disposition
Correct answer: License termination plan and radiological survey report confirming cleanup
License termination under 10 CFR 30.36 requires a license termination plan and a final radiation survey report demonstrating the site meets release criteria.
Question 6: A 'certificate of disposition' for low-level radioactive waste verifies that:
- The waste has been characterized per NRC release limits
- The receiving disposal facility has accepted the waste and processed it (Correct answer)
- DOT packaging requirements were met during shipment
- The generator's license allows waste disposal at the specified site
Correct answer: The receiving disposal facility has accepted the waste and processed it
A certificate of disposition confirms that the LLW disposal facility has received, accepted, and processed the waste shipment as manifested.
Question 7: Under 10 CFR 61, low-level radioactive waste is classified into Class A, B, and C based primarily on:
- Volume of the waste
- Radiological concentration of specific radionuclides and their half-lives (Correct answer)
- The type of facility that generated the waste
- Whether the waste is liquid or solid
Correct answer: Radiological concentration of specific radionuclides and their half-lives
10 CFR 61 classification is based on the concentration of short-lived and long-lived radionuclides in the waste, defining disposal stability and site requirements.
