この概要は現在英語のみで提供しています。

適用範囲

This standard applies to the administrative practices for nuclear criticality safety during the processing, handling, operation, and storage of fissile materials outside reactors. It is specifically designed for nuclear facility operating organizations and contractor organizations involved in these activities. This standard does not apply to the assembly of fissile materials under controlled conditions, such as subcritical and critical experiments.

技術要求

This standard establishes mandatory administrative regulations to govern nuclear criticality safety. It requires operating organizations to establish a robust criticality safety responsibility system, ensuring that every worker understands their role in maintaining safety. Facilities must appoint dedicated or part-time nuclear criticality safety professionals who possess the authority to advise leadership directly. Operating organizations must bear comprehensive responsibility for the criticality safety of their facilities and cannot transfer this obligation. The standard mandates rigorous nuclear criticality safety evaluations before initiating new operations or modifying existing processes and equipment. These evaluations must confirm that the entire operation remains in a subcritical safe state under both normal and credible abnormal conditions. All operational procedures involving criticality safety must be documented in writing and reviewed periodically by qualified personnel. Furthermore, the standard outlines specific requirements for personnel training, mandating regular and systematic education for operators, safety professionals, and management. It also details strict fissile material management protocols, requiring written procedures for material transfer, accurate inventory control, and clear labeling of storage locations with controlled parameter limits. Finally, the standard requires comprehensive preparation for nuclear criticality accident emergency response. Facilities must develop detailed emergency plans that include evacuation routes, personnel screening procedures, medical treatment protocols, and re-entry approvals. Any near-miss criticality accident must be investigated and managed with the same severity as an actual nuclear criticality accident.

試験方法

As an administrative standard, GB 15146.1-2008 does not prescribe specific physical or chemical testing methods. Instead, it mandates procedural evaluations such as nuclear criticality safety analysis and periodic operational safety inspections. These evaluations require verifying that actual facility conditions match the assumptions made in the safety analysis, ensuring that controlled parameters and their limits are strictly maintained during operations.

よくある質問

What operations are regulated under GB 15146.1-2008?

This standard applies to the administrative practices for nuclear criticality safety during the processing, handling, operation, storage of fissile materials outside reactors. It does not apply to the assembly of fissile materials under controlled conditions, such as subcritical and critical experiments.

Are there any significant updates from the previous version of GB 15146.1-2008?

The 2008 version primarily introduces the integration of a quality assurance system into the administrative framework. The majority of the other modifications are editorial, with a clear distinction made between mandatory requirements (using "shall") and recommendations (using "should").

How does GB 15146.1-2008 differ from international nuclear criticality safety standards?

While ISO standards provide general international guidelines for nuclear criticality safety, GB 15146.1-2008 establishes specific mandatory administrative regulations tailored to China's national regulatory framework. It defines explicit compliance obligations for both nuclear facility operating organizations and contractor organizations operating under Chinese jurisdiction.

The summary above provides a high-level overview of GB 15146.1-2008.
