Oklo’s Isotope Test Reactor achieves criticality
Oklo’s Groves Isotope Test Reactor became the fifth Department of Energy–authorized reactor to achieve criticality under the agency’s authorization process, it was announced earlier today.

The JCNRM Consensus Committee is responsible for the preparation and maintenance of voluntary consensus standards that establish safety and risk criteria and methods for completion of probabilistic risk analysis (PRA) and risk assessments. Additional related standards activities may be performed as upon concurrence of the ANS Standards Board and the ASME Standards & Certification Board. These criteria and methods are applicable to design, development, construction, operation, decontamination, decommissioning, waste management, and environmental restoration for nuclear facilities. Activities of the consensus committee shall be guided by the Procedures for ASME Codes and Standards Development Committees but shall also meet the intent of ANS Standards Committee Procedures Manual for Consensus Committees unless specifically authorized by the ANS Standards Board.
The JCNRM oversees the following 3 subcommittees:
- Subcommittee on Standards Maintenance (SC-SM)
- Subcommittee on Standards Development (SC-SD)
- Subcommittee on Risk Applications (SCoRA)
Volunteer placement is management by ASME. Individuals interested in JCNRM standards projects may contact standards@ans.org for information.
