M4D1: Nuclear Security
After you have completed reading “10CFR73.55: Requirements for Physical Protection of Licensed Activities in Nuclear Power Reactors Against
Radiological Sabotage,” post your answers to the following discussion questions.
Respond to the following:
• 10CFR73.55, item (b)(3)(ii) states that a facility’s security program must “provide defense in depth.” With regard to facility security,
what components would be included in “defense in depth”?
• 10CFR73.55, item (b)(9)(i) describes an “insider mitigation” program that, “must monitor the initial and continued trustworthiness and
reliability of individuals granted unescorted access to a protected or vital area” (USNRC, 2012, para. 18). What efforts do you think are required
to ensure trustworthiness and reliability of individuals?
M4D2: Quality Assurance Programs
After you have completed reading “Appendix B to Part 50—Quality Assurance Criteria for Nuclear Power Plants and Fuel Reprocessing Plants,” post your
answers to the following discussion questions.
Respond to the following:
• Appendix B, Section III, Design Control, contains the statement: “The verifying or checking process shall be performed by individuals or
groups other than those who performed the original design, but who may be from the same organization” (USNRC, 2012, para. 7). What is the purpose of
this statement?
• Appendix B, Section XVI, Corrective Action, states that: “Measures shall be established to ensure that conditions adverse to quality, such
as failures, malfunctions, deficiencies, deviations, etc. , are promptly identified and corrected” (USNRC, 2012, para. 20). How do you think human
performance (that is, performance of reactor operators, technicians, etc. ) would be addressed by the corrective action process?
