The intent of this script is to be run every 5-10 seconds with a systemd service and associated timer unit on a linux based EPICS SoftIOC. The simulation covers some of the signals associated with providing a reactor trip for a four loop pressurized water reactor.
For those who like reading lots of pdfs about the arcane practice of building a PWR and implementing reactor trip and ESFAS features, the source information is available on the NRCs site here.
I should probably make another repo with all of the documents on github for posterity when they notice or Westinghouse begins to care that those files are outward facing.
-
Spin up a linux image, it can be physical, virtual, container, whatever (tested on Arch running in VMware, pretty sure it'll work on Debian too.)
-
Install EPICS on it
- You'll need gcc, perl, git, python3, and systemd to make the shenanigans work
-
Once you can launch softIoc life is perdy good from the EPICS side
-
Install reactorsim.service and reactorsim.timer to /etc/systemd/system, have to enable the timer (but not the service) with:
systemctl enable --now reactorsim.timer
-
Make another VM (tested on Debian rinning in VMware)
-
Install Phoebus on it
-
If you aren't a maven wizard (I'm not), you'll want to do the JAVA_HOME config in /etc/profile. Or else maven will be grumpy with you and you will spend two bewildered days wondering where maven needs JAVA_HOME even though you can call
$JAVA_HOME/bin/java -version
and
$JAVA_HOME/bin/javadoc --version
from the command line just fine.
-
If you don't care about my ramblings, /etc/profile should have:
export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64 export PATH=\${JAVA_HOME}:\${PATH}
at the end of it. I'm sure newer java's work fine but I ended up down a pretty deep rabbit hole trying to figure out what was going on here. NOTE: '/usr/lib/jvm/default' did not seem to work. I have no idea why.

-
Pull 'main.bob' down and open it with Phoebus.
-
Make sure your two VMs/containers/machines can hit each other over the network
From there you should be able to fiddle with the HMI. For reactor startup:
