Section 4: General Principles
6. The licensee shall be primarily responsible for nuclear security of its nuclear material, nuclear fa-cilities, and activities.
7. The licensee shall consider and maintain nuclear security from the early stage of a nuclear facility.
8. The licensee shall ensure the availability of nuclear security measures that is commensurate with the threat assessment at each stage of the licensing process.
9. The licensee shall apply the requirements of this regulation based on the design basis threat or national threat assessment as prescribed by the NRRC.
10. The licensee shall set up physical protection measures for nuclear material based on its category, prior to arrival of the nuclear material on site.
11. The licensee shall ensure that the physical protection system is integrated and effective against both sabotage and unauthorized removal.
12. The licensee shall be responsible for ensuring that nuclear security interface with safety and nu-clear material accounting and control systems, and measures at the nuclear facility is mutually supportive as practicable.
13. Where potential conflicts between safety and security are identified, the licensee shall immedi-ately adopt compensatory and/or mitigative actions to maintain safety and security as prescribed by the NRRC.
Section 5: Categorization of Nuclear Material
14. The licensee shall apply security measures for protecting nuclear material and for preventing each level of potential radiological consequences based on the category as prescribed by the NRRC in Appendix I.
15. The licensee shall apply aggregation on the total amount of nuclear material in determining the categorization of the nuclear material in any specific location within the facility in identifying the physical protection measures for the unauthorized removal.
16. The categorization shall not be applicable in determining physical protection against sabotage, in which the licensee shall use the threshold for unacceptable radiological consequences prescribed by the NRRC.
Section 6: Responsibilities to the Competent Security Agencies
17. The licensee shall make documented, needed arrangements with competent security agencies to ensure that nuclear security measures are adequate to counter the threats identified in the de-sign basis threat.
18. The licensee shall arrange for the training and familiarization of the nuclear facility for the compe-tent security agencies as defined in the documented arrangements between the licensee and competent security agencies.
19. The licensee shall consult the offsite response force regarding the arrangements, resources, and the equipment available to the licensee and the off-site response force, and any other security re-lated matter at the facility.
20. Transfer of leadership responsibility during nuclear security event from the licensee to the offsite response forces shall be jointly agreed upon and documented in the contingency plans.
Section 7: Defense in Depth Principle
21. The defense in depth principle shall be applied in the design of the physical protection system for each of the functions of detection, delay, and response, with independent capabilities so that the failure of one capability does not mean loss of that function.
22. The licensee shall have protection measures combining design mixture of security devices, proce-dures and facility design that have to be overcome or circumvented by an adversary in order to achieve his objectives.
23. When implementing defense in depth principle, diversity and redundancy shall be considered ap-plying graded approach.
