% INTRODUCTORY PARAGRAPH Hook
Nuclear power plants require the highest levels of control system reliability,
where failures can result in significant economic losses, service interruptions,
or radiological release.\splitnote{Stakes established immediately — good hook.}

release.\splitnote{Stakes established immediately — good hook.}
% Known information
Currently, nuclear plant operations rely on extensively trained human operators
who follow detailed written procedures and strict regulatory requirements to
manage reactor control. These operators make critical decisions about when to
switch between different control modes based on their interpretation of plant
conditions and procedural guidance.

% Gap
This reliance on human operators prevents autonomous control capabilities and
creates a fundamental economic challenge for next-generation reactor
designs.
\splitinline{The ``and'' here joins two distinct issues (autonomy barrier +
economics). Consider making the causal link explicit: ``This reliance on human
operators not only prevents autonomous control capabilities but also
creates...'' or split into two sentences.}
Small modular reactors, in particular, face per-megawatt staffing costs far
exceeding those of conventional plants and threaten their economic viability.

manage complex operational sequences with the same assurance as human-operated
systems, but without constant human supervision.

% APPROACH PARAGRAPH Solution
To address this need, we will combine formal methods with control theory to
build hybrid control systems that are correct by construction.
% Rationale
Hybrid systems use discrete logic to switch between continuous control modes,
mirroring how operators change control strategies. Existing formal methods can
generate provably correct switching logic from written requirements, but they
cannot handle the continuous dynamics that occur during transitions between
modes. Meanwhile, traditional control theory can verify continuous behavior but
lacks tools for proving correctness of discrete switching
decisions.\splitnote{Excellent setup of the gap — shows why neither approach
mirroring how operators change control strategies. Existing formal methods
can generate provably correct switching logic from written requirements, but
they cannot handle the continuous dynamics that occur during transitions
between modes. Meanwhile, traditional control theory can verify continuous
behavior but lacks tools for proving correctness of discrete switching
decisions.\splitnote{Excellent setup of the gap — shows why neither approach
alone is sufficient.}
% Hypothesis
By synthesizing discrete mode transitions directly from written operating
procedures and verifying continuous behavior between transitions, we can create
hybrid control systems with end-to-end correctness guarantees. If existing
procedures can be formalized into logical specifications and continuous dynamics
verified against transition requirements, then autonomous controllers can be
built that are provably free from design
procedures and verifying continuous behavior between transitions, we can
create hybrid control systems with end-to-end correctness guarantees. If
existing procedures can be formalized into logical specifications and
continuous dynamics verified against transition requirements, then autonomous
controllers can be built that are provably free from design
defects.\splitnote{Hypothesis is clear and testable.}
% Pay-off

maintaining the high safety standards required by the industry.
