Dry Fuel Storage Radiation Monitoring
In addition to the ongoing, 24/7 radiation monitoring within and along the perimeters of the plant, SCE is installing a separate system specifically for the dry spent fuel storage facility. Though the system is not required by the NRC, it was first suggested by a community member and SCE agreed to install the monitors to provide additional information to the public. Only one other nuclear plant site in the U.S. has such a program.
We are working with independent partners who will assist with the program including the California Dept. of Public Health Radiologic Health Branch and California State Parks.
Learn more about spent nuclear fuel storage from the Nuclear Regulatory Commission's FAQs.
The on-site monitors will feed real time radiation readings from three locations on the storage pad to the partners, and the state Radiologic Health Branch will produce a monthly report for the public, which will be posted on this page once underway.
The report will include the high, low and average radiation readings from these locations, and provide context so that the public can understand what the levels are and how they translate into the everyday world. We expect this program to be underway during the first quarter of 2020.
