\section*{Problem 6}
|
|
\subsection*{Part A}
|
|
|
|
Core design that prohibits adequate transfer of power between core regions will
|
|
increase the likelihood of oscillations. In our notes for 'Simplified Parallel
|
|
Coupled Reactors', we summarized this communication between reactor regions as a
|
|
parameter $g$. Designs that have connections between areas with small $g$ will
|
|
suffer from worse oscillations. I would presume reactors that have large aspect
|
|
ratios would suffer more from oscillations, as it would be harder for different
|
|
ends of the reactor core to 'communicate' with one another.
|
|
|
|
\subsection*{Part B}
|
|
|
|
These oscillations will cause damage to the fuel and reactor over time. The
|
|
reactor is presumably not designed to carry such high power loads in localized
|
|
regions of the reactor, as opposed to a balanced power load across the entire
|
|
reactor core.
|
|
|
|
\subsection*{Part C}
|
|
|
|
Oscillations might impact core protection or safety analysis by obscuring the
|
|
actual reactivity or temperature values inside the reactor core. Without proper
|
|
care to obtain good measurements, a reactor operator could not be aware that
|
|
certain oscillating areas of the core are exceeding temperature and local power
|
|
limits, all the while the reactor as a whole may appear as if it's behaving
|
|
normally. The result is that while coolant flow in and out of the reactor
|
|
maintain normal temperature, oscillating fuel rods may actually be pushing
|
|
beyond designed limits, and compromising their cladding, performance, or other
|
|
important characteristics..
