RNWBL Shares How Their App Can Save Time and Increase Productivity for Technicians in the Field

The objective of FLEX is to establish an indefinite coping capability to prevent damage to the fuel in the reactor and spent fuel pools and to maintain the containment function by using plant equipment and FLEX equipment. This capability will address an extended loss of AC power (i.e., loss of off-site power, emergency diesel generators, and any alternate AC power sources) concurrent with a loss of ultimate heat sink, which could arise following external events that are within the existing design basis with additional failures and conditions that could arise from beyond-design-basis external events. Since the beyond-design-basis regime is essentially unlimited, plant features and insights from beyond-design-basis evaluations are used, where feasible, to inform coping strategies.

The underlying strategies for coping with these conditions involve a three-phase approach:

1. Initially cope by relying on plant equipment.
2. Augment or transition from plant equipment to on-site FLEX equipment and consumables to maintain or restore key functions.
3. Obtain additional capability and redundancy from off-site FLEX equipment until power, water, and coolant injection systems are restored or commissioned.

Last month, we asked our audience: how prepared is your nuclear plant to implement FLEX strategies to mitigate beyond design-basis events? Overall, 50 percent voted that their plant was very well prepared to implement FLEX strategies. Additionally, 33 percent voted that they were adequately prepared, 8 percent voted somewhat prepared, and 9 percent voted that they were not prepared.
