3. DESCRIPTION OF PROBLEM OR FUNCTION

ORCOST2 estimates the cost of electrical energy production from single-unit steam-electric power plants. Capital costs and operating and maintenance costs are calculated using base cost models which are included in the program for each of the following types of plants: PWR, BWR, HTGR, coal, oil, and gas. The user may select one of several input/output options for calculation of capital cost, operating and maintenance cost, levelized energy costs, fixed charge rate, annual cash flows, cumulative cash flows, and cumulative discounted cash flows. Options include the input of capital cost and/or fixed charge rate to override the normal calculations. Transmission and distribution costs are not included. Fuel costs must be input by the user.

4. METHOD OF SOLUTION

The code follows the guidelines of AEC Report NUS-531. A base capital-cost model and a base operating- and maintenance-cost model are selected and adjusted for desired size, location, date, etc. Costs are discounted to the year of first commercial operation and levelized to provide annual cost of electric power generation.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

The capital cost models are of doubtful validity outside the 500 to 1500 MW(e) range.

[ top ]

6. TYPICAL RUNNING TIME

Execution time for a single case is less than one second on the IBM 360/91.

7. UNUSUAL FEATURES OF THE PROGRAM:

[ top ]

8. RELATED AND AUXILIARY PROGRAMS

Capital cost calculations are based on the cost-model data developed for the CONCEPT program (NESC Abstract 498). A separate code OMCST (NESC Abstract 688) can be used to calculate nonfuel operation and maintenance costs.
