R3K Control System Interpreter

• Options to develop Control System
• RELAP5 Input Deck
• boring
• complex when logics involved
• changes require re-snap ICs
• 3KeyMaster task C program
• have to build task
• Symbolic Calculations and Transfer - SCATER
• implemented in YACC
• invoked on every time step
• no declarations, simple and handy
