Japan-U.S. decommissioning workshop coming up

January 19, 2024, 12:00PMANS Nuclear Cafe

The Japan-U.S. Decommissioning Workshop Series continues on February 8–9 when its second forum meets to discuss the handling of low-level radioactive waste (LLW) generated during the decommissioning process and how improved LLW management can reduce risk.

Registration for the online event is required. The registration deadline is 2:00 a.m. (EST) on February 5.

Objective: One goal of the workshop series is to discuss risk management in nuclear decommissioning—specifically, risks in completing projects in a safe and timely manner. In addition to sharing lessons learned in reducing technical risk, another goal is to share U.S. experiences in decommissioning projects, including technical issues and other subjects like regulatory processes, financial structures, and communicating progress with the local community.

The scope of the workshop series will be limited to decommissioning operations at power plant sites and will not include topics such as the selection of a disposal site. Decommissioning of a post-accident reactor will not be directly covered.
