How Nuclear Power Can Transform Electric Grid and Critical Infrastructure Resilience
rPP / rNPP Functional Requirements translate to in terms of quantitative functional requirements on the rNPP ? How much real and reactive load following capability is needed and what ramp rates are required ? Which specific types of flexible operations are required and are the time frames , relative power levels , ramp rates , etc . required to fulfill flexible operations needs ? How long must the rNPP be capable of Island Mode operation , and what are the conditions for transfer into and out of Island Mode operation ? Quantitative answers to these questions and many others are required to enable the design and evaluation of specific rNPP concepts .

Developing Virtual Grid Resilience Assessment Model
Both coarse and highly granular computer simulations of actual Grid systems or synthetic Grid test systems are needed to assess the reliability , operability , and resilience implications of insertion of rNPPs into the Grid ( Table 5 , Item 2 ). Such simulations can illuminate a number of important issues such as : optimal rNPP / Grid siting strategies ; promising rNPP-Grid interface approaches ; the impacts of rNPPs on Grid reliability , availability , load flow , and stability during normal operations and extreme Grid events ; optimal approaches for maximizing the black start value of rNPPs ; and Grid transmission and distribution system modifications that would enhance the overall utility of rNPPs . The use of synthetic virtual test systems ( such as IEEE Bus test systems ) certainly have their place in such studies . The need also exists to examine the use of rNPPs as actual elements of today ’ s integrated
