  3.5-1998 (Current simulator was certified with
  version 1985 of this ANSI, most plants in the USA
  use this standard)
• Run a training scenario from any place in the
  world via Internet

Conclusions (UNAM Activities)

• Introductory and basic training, complementary
  integral operator training, and specialized
  safety analysis capabilities for normal,
  abnormal, accident and severe accident
  management.
• RELAP/SCDAPSIM based system for LVNPP uses a
  flexible, yet detailed input model and
  combinations of generic and specific graphical
  displays.
• Advanced human-machine
• Applications operator performance evaluation,
  human factors engineering for instrument and
  control panel design and optimization, system
  specification, development and verification, task
  environment constraints, and virtual reality
  environments.
• University staff and students have access to
  advanced reactor analysis software to support
  academic and research activities.
