Priority Function Secondary

In the case where it is acceptable to schedule an operator, but not imperative to do so immediately, the decision will be passed on to the secondary priority function. 

If the secondary function determines that placement of the current operator would violate the maximum hardware specifications, one of two actions will take place. If the user has chosen to run in "hard mode, the maxlist values are accepted as hard limits that cannot be violated by the scheduler, so a negative value is returned by the priority function so that placement is delayed. If, however, the user has chosen "soft mode," wherein the initial maxlist values imply a lower limit on hardware and CSTEP may choose higher limits according to utilization, the tertiary priority function is invoked. 

Over 30% of patients with dementia develop a group of secondary behavioral disturbances, including depression, hallucinations and delusions, agitation, insomnia, and wandering. Because these secondary symptoms impair patients functions, increase their need for supervision, and often influence the decision to institutionalize them, the control of these symptoms is a priority in managing AD. 

Extreme recovery measures will usually be implemented only with increasing severity of the challenge. For example, if a safety function restoration measure could result in severe damage to important plant equipment (e.g. a primary coolant pump, a secondary system, etc.) this measure will only be taken when all other possible restoration measures have been tried and have failed. The actions that must be taken are strictly a matter of priority. The optimal recovery procedures would normally be written in such a way as to protect the integrity of plant systems and equipment. However, since plant systems and equipment have a lower priority than the reactor core and preventing the release of radioactivity they will be sacrificed before the latter are allowed to occur.
