## Morning Brief

Yesterday I finished two additional thesis ideas and got
|
|
||||||
some more reading done

## Morning Brief
|
|
||||||
I didn't do shit. But I emailed Dan that I'd be OOO
|
|
||||||
Wednesday and Thursday for the motorcycle course.
|
|
||||||
|
|
||||||
I'm finishing those fucking thesis ideas today. ON GOD.

|
|
||||||
I'm' also supposed to have a date with Miranda today, but
|
|
||||||
she hasn't texted me back. Interesting. Jackie also
|
|
||||||
complimented my socks and show combo. That was nice. I
|
|
||||||
showed her and Natan [Angus](ourcowangus.com).

## Morning Brief
|
|
||||||
I didn't finish the thesis ideas from yesterday. Oopsie!
|
|
||||||
Today is different though. Curently, I'm working from
|
|
||||||
home^*, which really means I'm working in a coffee shop on
|
|
||||||
Washington road. I'm at the Orbis Cafe, where I purchased a
|
|
||||||
cinnamon roll and a cappucino. The caffeine has yet to hit,
|
|
||||||
but when it does, I'll be cooking I'm sure. This is a nice
|
|
||||||
spot and it's very relaxing to get things done while other
|
|
||||||
people are around. I like this a lot, and perhaps I should
|
|
||||||
do this more often while I'm at school too.
|
|
||||||
|
|
||||||
Anyways, Dan is OOO taking time off while he can before the
|
|
||||||
fall semester. Who can blame him?
|
|
||||||
|
|
||||||
Patrick and I discussed more PINN stuff yesterday. I should
|
|
||||||
make a simple PINN demonstration.

### Goals:
|
||||||
The goal of this research is to use machine learning to
|
|
||||||
identify system faults of a reactor control system during
|
|
||||||
runtime. A digital twin will be compared to measurements
|
|
||||||
from a real plant to identify issues such as coolant losses,
|
|
||||||
sensor and actuator failures, or component degredation so
|
|
||||||
that safety strategic decisions about the plant can be made
|
|
||||||
autonomously.
|
|
||||||
|
|
||||||
### Outcomes:
|
### Outcomes:
|
||||||
For this research to be successful, I will accomplish the
|
|
||||||
following:
|
|
||||||
|
|
||||||
- Create a simulation suite for the Small Modular Advanced
|
|
||||||
High Temperature Reactor (SmAHTR) to simulate fault
|
|
||||||
conditions of sensors, actuators, and component degradation.
|
|
||||||
|
|
||||||
- Develop a physics informed neural network (PINN) approach
|
|
||||||
to evaluate physics discrepancies in measured signals and
|
|
||||||
to estimate physically relevant parameters to determine
|
|
||||||
real system divergence from the nominal plant.
|
|
||||||
|
|
||||||
- Realize a proof of concept autonomous controller than can
|
|
||||||
react to fault conditions by switching to different
|
|
||||||
control modes rather than only responding with reactor
|
|
||||||
shutdown.
|
|
||||||
|
|
||||||
### Impact:
|
### Impact:
|
||||||
The nuclear energy industry's largest expense is operations
|
|
||||||
and maintenance (O&M). These costs include typical reactor repair
|
|
||||||
and refueling, the labor involved to complete such
|
|
||||||
maintenance, and finally the labor involved in operating the
|
|
||||||
reactor itself. Currently the largest of these O&M expenses
|
|
||||||
is the labor and part cost used in maintenance, while large
|
|
||||||
nuclear reactor facilities require a modest reactor operator
|
|
||||||
budget per megawatt of energy produced. The advent of small
|
|
||||||
modular reactors (SMRs) and microreactors (MRs) will change
|
|
||||||
these economics significantly.
|
|
||||||
|
|
||||||
As SMRs and MRs become more common, the cost of repair and
|
|
||||||
maintenance should reduce dramatically as nuclear power
|
|
||||||
componnets will become modular, replaceable parts instead of
|
|
||||||
the bespoke reactor designs currently operating. Operator
|
|
||||||
wages, however, can be expected to increase without
|
|
||||||
introducing greater controller autonomy. SMRs and MRs are
|
|
||||||
much smaller output designs per reactor core, and if they
|
|
||||||
are required to employ the same size reactor operator team
|
|
||||||
as a conventional large reactor, will suffer from much
|
|
||||||
larger operator expense per megawatt. Greater controller
|
|
||||||
autonomy can solve this problem by unloading some reactor
|
|
||||||
control responsibilities from the operator, and therein
|
|
||||||
reduce labor consumption.
|
|
||||||
|
|
||||||
<# TO DO #>
|
|
||||||
Finally reactor safety can be improved by greater autonomy
|
|
||||||
yada yada find some reasons to back this up.
