example 1

[0249] Example 1. A multi-modular power plant comprising: a plurality of on-site nuclear power modules configured to generate a power plant output; a number of power plant systems configured to use power associated with a plant load of the power plant to operate; and a switchyard configured to electrically connect the electrical equipment to a distributed grid, wherein the distributed electrical grid is configured to serve a plurality of geographically dispersed consumers, electrically connect the electrical equipment to a dedicated electrical grid , wherein the private grid is configured to supply electricity generated from the electric plant output to a private service load, and wherein the electric plant output is equal to or greater than the combined load of the private service load and the utility load; and the electric plant At least a portion of the output is distributed to both the power plant system and the private grid.

example 2

[0250] Example 2. The multiple modular electrical equipment of example 1, wherein said dedicated service load comprises one or more consumers located off-site of said electrical equipment, and wherein said electrical equipment is configured to Provides consumers with substantially continuous power via the private grid during periods of power outages on the private grid.

example 3

[0251] Example 3. The multiple modular electrical equipment of example 1, wherein the plurality of electrical equipment systems configured to operate using electricity associated with the utility load includes a non-emergency system, and wherein the electrical equipment is further Several passive emergency systems are included that are configured to operate without any electricity.

Abstract

A multi-modular power plant may include a plurality of on-site nuclear power modules configured to generate a power plant output, wherein one or more of the nuclear power modules may be designated asservice module units which are configured to generate a first portion of the power plant output. A remainder of the nuclear power modules may be configured to generate a second portion of the power plant output. A number of power plant systems may be configured to operate using electricity associated with a house load of the power plant, wherein the first portion of the power plant output is equalto or greater than the house load. Additionally, a switchyard may be configured to electrically connect the power plant to a distributed electrical grid. The distributed electrical grid may be configured to service a plurality of geographically distributed consumers, and the switchyard may be configured to apply the second portion of the power plant output to the distributed electrical grid. Theswitchyard may further be configured to apply at least part of the first portion of the power plant output to the power plant systems during a loss of power from the distributed electrical grid.
