DC Cook has a Rod Drop System that we created ~16 years ago and have upgraded over the years. Our system cannot take over 5 volts, so we have to turn power off to the RPIs prior to hooking up the 53 cables to the RPI Test Points We have the ARPI system We are looking at reliability and shorter outages and want to see what others are using and who performs the test.
So for Rod Drop Timing Tests: What kind of RPI system do you have (ARPI, DRPI)? Where do you hook the Rod Drop System to?
What kind of Rod Drop Timing system do you have? Is it permanently installed, will it take data at all times?
Do you have a contractor come in and do the measurement? Who is your contractor?
What organization performs the test (Reactor Engineering, MTI, Operations, etc)?
When do you perform the rod drops (in parallel with CRDM Time Response Testing, in parallel with physics testing, etc)
How labor intensive is your process from setup to dropping to analysis (fully automated with little setup, very little automation and a lot of setup, etc.)?
