Thanks to everyone who provided input to this question! The responders who identified Be-7 were correct. Our decay and half-life determination concluded Be-7 as the nuclide.
I was initially not inclined to identify Be-7 in the reactor coolant system as my experience has been that this is a naturally occurring isotope. Thanks to the response of many Radsafers, I now know that it is an isotope formed in pressurized water reactors.
