WSC and Idaho National Labs (INL) continue to work together to enhance the Advanced Test Reactor (ATR) with several small upgrade projects awarded this year, including:

• Low Pressure Instrument Air Model update due to INL replacing the 3 different compressors that provide low-pressure air for the ATR with 2 new compressors, providing the same air pressure that is currently utilized. The 3 older compressors will provde air to areas outside the plant.
• Transformer Model Upgrade to reflect INL replacing two transformers in the 4160V electrical distribution along with additional relays, which are being incorporated, that can be controlled from the control room.
• Replacement CDS HMI support in a 3-phase project by providing assistance in the development of a modernized design for the CDS and Annunciator HMI screens, using 3KEYMASTER to support 1) General HMI Screen Layout, 2) HMI Screen Refinement, and 3) incorporating the changes derived from phases 1 and 2 into an updated version of the CDS and Annunciator emulation.
• I/O System Upgrade to replace the aging National Instruments I/O hardware system and hard to maintain Arcaus computer with a new Ethernet-based TMI I/O system.
