3. DESCRIPTION OF PROBLEM OR FUNCTION

The CONCEPT computer code system was developed to provide conceptual capital cost estimates for nuclear and coal-fired power plants. Cost estimates can be made  as a function of plant type, size, location, and date of initial operation. The output includes a detailed breakdown of the estimate  into direct and indirect costs similar to the accounting system described in document NUS-531. Cost models are provided in CONCEPT5, the fifth generation in the development of the CONCEPT package, for  single-unit coal-fired plants, pressurized-water reactors, boiling-  water reactors, liquid-metal-cooled reactors, and multi-unit coal- fired plants based on today's average or best operating experience.  Costs may be obtained for any of twenty U.S. cities, a hypothetical  Middletown site, and two Canadian cities. CONCEPT5 models are updated models of those available in CONCEPT3 and, in addition, this edition contains historical factory equipment cost data for the generation of cost indices and escalation rates; indirect costs are  calculated as a function of unit size rather than a function of direct costs; and an indirect cost account for owner's costs and an  improved time-dependent escalation feature are included.
The CONCEPT3 models and cost data are outdated; the package is being retained in the library since it is the only UNIVAC1108 machine version of CONCEPT available and could prove helpful in converting the latest IBM release.

4. METHOD OF SOLUTION

CONCEPT is based on the premise that any central station power plant involves approximately the same major cost components regardless of location or date of initial operation. The program has detailed cost models for each plant type at a reference condition. Through use of size, time, and location- dependent cost adjustments, a reference cost model is modified to produce a specific capital cost estimate.
CONCEPT is supported by two auxiliary programs--CONTAC, which generates and maintains the cost-model data file, and CONLAM, which  generates and maintains the equipment, labor, and materials historical cost data file.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

CONCEPT5 accepts power levels of 500 to 1500 MW(e) for nuclear plants and 300 to 1000 MW(e) for coal-fired plants, while CONCEPT3 accepts levels of 500 to 2000 MW(e). The auxiliary program CONLAM is limited to 30 time periods of historical cost data for 23 locations without program alterations.

6. TYPICAL RUNNING TIME

A single CONCEPT5 or CONCEPT3 cost estimate is generated in less than 1 minute.
NESC0498/08
NEA-DB implemented the different modules of this package on an IBM 3090 computer and executed the test case of CONCEPT-5 in 1sec40 of CPU time.

7. UNUSUAL FEATURES OF THE PROGRAM

CONCEPT utilizes execution-time NAMELIST variations of stored constants, printer plotting of cash flow curves, and numerous output and solution options.

8. RELATED AND AUXILIARY PROGRAMS

CONCEPT requires the use of CONLAM  to generate a user file of labor and materials cost history and CONTAC to generate a user file of cost models.

11. MACHINE REQUIREMENTS

Less than 270K bytes, four scratch file, two  support files, and the standard I/O units are required for CONCEPT5; 150K bytes, one scratch disk or tape, two support tapes, and the standard I/O units are needed for CONCEPT3.
NESC0498/08
To run the test case of CONCEPT-5 on an IBM 3090, 235 Kbytes of main storage are required.

14. OTHER PROGRAMMING OR OPERATING INFORMATION OR RESTRICTIONS

The
CONCEPT5 main program and the CONTAC5 auxiliary program use a local  BAL subroutine called IDAY. The routine is used to obtain the date of the run. The ORNL routine is included in the package but should be replaced with the equivalent subroutine in the local environment.
