Starting a New Scenario¶
We will start with a new scenario representing a simplified once-through fuel cycle. For the purpose of this tutorial, the scenario will include:
- mine of natural uranium
- enrichment facility producing 4% enriched uranium oxide fuel
- LWR reactor consuming fresh fuel and producing used fuel
- repository to house all spent fuel
More details about each of these facilities will discussed when we are required to provide that input.
Activity: Open the Main View¶
To begin a new scenario:
- Select the Scenario Builder tab in the workspace.
- Drag the Main View tool and drop it into the workspace.
This view has the following sections:
- Simulation details
- Archetype discovery
- Commodity List
- Archetype ribbon
- Fuel cycle design pane
Concept: Simulation Time Steps¶
Cyclus uses a time-step approach to march through time and determine what actions are taken by each agent at each point in time. Each time step includes the following phases:
- new agents may enter the system (deployment)
- each agent prepares for exchange of material
- agents engage in material trades
- each agent acts after the exchange of material
- agents may leave the system (decommissioning)
Users do not have to manage these phases, but must provide the following information for all simulations:
- Duration: the number of months to be simulated
- Start Month: the first month of the simulation
- Start Year: the first year of the simulation
- Decay treatment: Turn off all decay (“never”) or allow individual archetypes to implement it
- Simulation Handle: An optional unique identifier for this particular simulation.
- Description: A brief discription for your benefit.
We’ll return later to the topics of generating, loading and executing an input file.
Activity: Set Simulation Parameters¶
The top level simulation parameters are shown in the Simulation Details pane (see below).
Enter the following data:
- Duration: 600
- First Month: June
- First Year: 2015
- Decay: Never
- Simulation Handle: leave blank for default simulation handle
