ESTS0176 RECAP.

1. NAME OR DESIGNATION OF PROGRAM:  RECAP, replacement energy cost
analysis

3. DESCRIPTION OF PROGRAM OR FUNCTION

RECAP (Replacement Energy Cost  Analysis Package) determines the replacement energy costs associated with short-term shutdowns or deratings of one or more nuclear reactors. Replacement energy cost refers to the change in generating-system production cost that results from shutting down a reactor. The cost calculations are based on the seasonal, unit-specific cost estimates for 1988-1991 for all 117 nuclear electricity-generating units in the U.S. RECAP is menu-driven, allowing the user to define specific case studies in terms of parameters such as the units to be included, the length and timing of the shutdown or derating period, the unit capacity factors, and the reference year for reporting cost results. In addition to simultaneous shutdown cases, more complicated situations, such as overlapping shutdown periods or shutdowns that occur in different years, can be examined through use of a present-worth calculation option.

4. METHOD OF SOLUTION

The user selects a set of units for analysis, defines a shutdown (or derating) period, and specifies any planned maintenance outages, delays in unit startups, or changes in default  capacity factors. The program then determines which seasonal cost numbers to apply, estimates total and daily costs, and makes the appropriate adjustments for multiple outages if they are encountered. The change in production cost is determined from the difference between the total variable costs (variable fuel cost, variable operation and maintenance cost, and purchased energy cost)  when the reactor is available for generation and when it is not. Changes in reference-year dollars are based on gross national product (GNP) price deflators or on optional use inputs.
Once RECAP has completed the initial cost estimates for a case study (or series of case studies), present-worth analysis can be conducted using different reference-year dollars and discount rates, as specified by the user. The program uses default values for gross national product price deflators unless user-defined cost adjustment factors are entered.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

Maximum of 25 case-  study files. Care should be exercised in applying the replacement energy cost estimates to shutdowns of a year or more, because in such cases utilities would probably seek more-optimum solutions to the loss of a nuclear unit. Long-term adjustments of this nature are not included in this analysis.

6. TYPICAL RUNNING TIME

NESC executed the sample problem in approximately 1.5 minutes on an IBM PC/AT.

7. UNUSUAL FEATURES OF THE PROGRAM

Where the user is looking for less case-specific evaluations, RECAP provides a review option for scanning the seasonal costs ($/day) for each unit. This option is useful for a rapid review of cost sensitivities as a function of season and reactor.
