30 30 SNCs Mission in the face of a pandemic threat To continue the uninterrupted maximum generation and delivery of electrical energy from the nuclear reactors at all three sites, considering mandated minimal staffing levels that are on-hand for an extended period of time and that there are no allowable compromise of the public health, public safety or violations of then-in-effect regulations in doing so.
Implementation The specified task would be to keep electricity flowing uninterrupted at maximum loads for all six nuclear units.
- Implied in that is the suggested establishment of minimum manning documents for not only numbers of employees present for duty but minimums assigned in several duty functions.
- Falling below these pre-established minimums at any location might necessitate voluntary derate or even shutdown of selected nuclear units, in a logical, stepwise manner.
- Likewise, there may be a hierarchy of necessary plant services and necessary Corporate services beyond which nuclear unit operations would not be prudent, regulatorily allowable or even possible SNC Mission and Implementation Statement in the event of a pandemic Pandemic Plans Pandemic Plans
