The existing PEIS model requires:
The non-integrated version of SCM (PEIS model) has the following programming elements.
The main task will be to further automate and integrate the PEIS models. Appropriate modifications and developments for SCM are established through prototyping. SCM will not initially include the socioeconomic and bottom-up model (although they may be added later). The minimum features of SCM (Version1.0) will include the following:
The system will also include on-line help screens and other features to increase user-friendliness to allow the system to be used by a wider audience. It will also feature a report generator with expanded report generation including graphical output. Output data includes module capacities and costs.

SCM includes cost input elements for items such as labor, construction, O&M,D& D, infrastructure, and costs per volume of waste. Users will have the capability to select, enter, or change data including site-specific cost factors, existing or new DOE facility cost information, commercial total or unit costs, off-site DOE treatment total or unit costs, and cost escalation factors. This may be a way to factor in contingent or external costs that have been excluded in the estimation. For example, users can change operating cost contingency percentages to factor in contingent costs due to environmental variables. Cost per unit volume of waste can be modified to include external costs. However, users will need to develop these estimates. No additional cost elements can be added.
SCM uses cost capacity relationships and internal data that have been developed for treatment and disposal processes for radioactive waste. The cost estimating modeling techniques used in the Volume Input Model and the Waste Management Estimating Program Model will be used in SCM. The total life-cycle costs will be calculated in three different modules for the waste types. low level waste, mixed low-level waste, and transuranic waste. SCM will have an eight element WBS:
SCM estimates costs based on internal cost and schedule data, facility capacity and operating parameters, facility costs, maximum and minimum scaling factors for parametric cost/capacity equations, transportation miles and costs/mile, standard operating parameters, and a standard rate table. SCM also features waste load inventory data from 50 DOE sites including an allowance for complex cost roll-ups.
Thus, users enter input data, or accept default values for a variety of elements including waste load by site and waste type, treatment technology option by site, site schedules by site and waste type, existing or planned approved facilities, and site specific cost factors. SCM will estimate costs based on user-input and default information, and parametric relationship models.
| Net present value (NPV) | --- |
| Payback period | --- |
| Internal rate of return (IRR) | --- |
| Benefits cost ratio | --- |
| Other | --- |
Although the software model is still under development, the methodology can be reviewed in a series of reports that are being prepared by Lockheed that describe preconceptual designs and planning level life-cycle cost estimates for four waste categories: Low level waste, mixed low-level waste, transuranic waste, and hazardous waste.
SCM will be designed to allow easy updating and addition of features. Users can select, enter, or change a variety of data types, which allows the evaluation of various options. Costs of new versus existing facilities can be compared. Anticipated enhancements for versions 1.3 and 2.0 include expanded integration and automation of the cost model and extensions such as risk indicators. Other considerations include interface to an interactive scheduling tool, user specification of module capacities, and variations in mass/volume reduction treatment factors to reflect technology improvements.
SCM does not include environmental liability (contingent) and external costs. No financial indicators are generated to compare options and results. However, present value analysis may be included in future versions of SCM. SCM is designed primarily with the purpose of estimating waste management facility costs. It does not assist in generating waste minimization options or pollution prevention.
