00:00:04.865 --> 00:00:06.240 align:middle line:84%
LIZ MULLER: I
believe the biggest

00:00:06.240 --> 00:00:10.720 align:middle line:84%
barrier to nuclear energy
isn't new reactor technology.

00:00:10.720 --> 00:00:11.740 align:middle line:90%
It's time.

00:00:11.740 --> 00:00:15.840 align:middle line:90%


00:00:15.840 --> 00:00:17.800 align:middle line:84%
For decades, many
in our industry

00:00:17.800 --> 00:00:20.520 align:middle line:84%
have followed the
same tired playbook.

00:00:20.520 --> 00:00:23.800 align:middle line:84%
Design a reactor, show
it works on paper,

00:00:23.800 --> 00:00:26.620 align:middle line:84%
then try to figure out how
to commercialize the design.

00:00:26.620 --> 00:00:30.000 align:middle line:90%


00:00:30.000 --> 00:00:32.600 align:middle line:90%
I think there's a better way.

00:00:32.600 --> 00:00:35.920 align:middle line:84%
Deep Fission's goal is to
focus on commercial deployment

00:00:35.920 --> 00:00:37.320 align:middle line:90%
from the start.

00:00:37.320 --> 00:00:40.640 align:middle line:84%
We're not trying to invent
a new type of reactor.

00:00:40.640 --> 00:00:44.280 align:middle line:84%
The technology we are utilizing,
pressurized water reactors,

00:00:44.280 --> 00:00:48.640 align:middle line:84%
has been deployed for decades
in commercial power generation

00:00:48.640 --> 00:00:52.720 align:middle line:84%
and uses readily available
low-enriched uranium fuel.

00:00:52.720 --> 00:00:58.000 align:middle line:84%
As of 2025, there are 64 safely
operating PWRs in the United

00:00:58.000 --> 00:01:04.239 align:middle line:84%
States, generating about 12%
of our nation's electricity.

00:01:04.239 --> 00:01:07.100 align:middle line:84%
Due to this legacy of
continuous operation,

00:01:07.100 --> 00:01:11.200 align:middle line:84%
criticality is not our
primary technical proof point.

00:01:11.200 --> 00:01:13.380 align:middle line:84%
Our difference is
our deployment model.

00:01:13.380 --> 00:01:15.960 align:middle line:90%


00:01:15.960 --> 00:01:19.700 align:middle line:84%
The gravity nuclear reactor
leverages existing capabilities

00:01:19.700 --> 00:01:23.340 align:middle line:84%
developed in the oil, gas,
and geothermal industries

00:01:23.340 --> 00:01:27.160 align:middle line:84%
to deploy established PWR
technology in a new way.

00:01:27.160 --> 00:01:29.700 align:middle line:90%


00:01:29.700 --> 00:01:32.700 align:middle line:84%
This involves novel
emplacement of PWRs

00:01:32.700 --> 00:01:35.540 align:middle line:84%
in mile deep boreholes
underground, utilizing

00:01:35.540 --> 00:01:38.540 align:middle line:84%
the rock itself to provide
structural confinement

00:01:38.540 --> 00:01:40.580 align:middle line:84%
and shielding,
along with pressure

00:01:40.580 --> 00:01:42.820 align:middle line:84%
from a mile-long
column of water on top

00:01:42.820 --> 00:01:44.940 align:middle line:90%
of the reactor in the borehole.

00:01:44.940 --> 00:01:47.820 align:middle line:84%
This reduces the need for
large surface infrastructure

00:01:47.820 --> 00:01:50.780 align:middle line:84%
associated with conventional
nuclear power plants,

00:01:50.780 --> 00:01:54.180 align:middle line:84%
allowing us to streamline
deployment of a technology we

00:01:54.180 --> 00:01:55.640 align:middle line:90%
already understand.

00:01:55.640 --> 00:01:58.180 align:middle line:90%


00:01:58.180 --> 00:02:00.500 align:middle line:84%
Deep Fission is
prioritizing validation

00:02:00.500 --> 00:02:02.940 align:middle line:84%
of the hardest and most
differentiated parts

00:02:02.940 --> 00:02:06.580 align:middle line:84%
of our system to reduce risk
earlier and move more directly

00:02:06.580 --> 00:02:08.860 align:middle line:90%
toward a commercial outcome.

00:02:08.860 --> 00:02:11.580 align:middle line:84%
We are working closely with
both the Department of Energy

00:02:11.580 --> 00:02:14.460 align:middle line:84%
and the Nuclear Regulatory
Commission to align

00:02:14.460 --> 00:02:16.580 align:middle line:84%
demonstration and
licensing, aiming

00:02:16.580 --> 00:02:20.700 align:middle line:84%
to move these efforts
forward in parallel.

00:02:20.700 --> 00:02:24.480 align:middle line:84%
In December 2025, we broke
ground in Parsons, Kansas,

00:02:24.480 --> 00:02:27.740 align:middle line:84%
in furtherance of participation
in the DOE Reactor Pilot

00:02:27.740 --> 00:02:29.260 align:middle line:90%
Program.

00:02:29.260 --> 00:02:32.020 align:middle line:84%
We have already drilled our
first data acquisition well

00:02:32.020 --> 00:02:36.070 align:middle line:84%
to gather real-world
data up to 6,000 deep.

00:02:36.070 --> 00:02:37.990 align:middle line:84%
Next, we will
demonstrate our ability

00:02:37.990 --> 00:02:40.390 align:middle line:84%
to drill a commercial
scale borehole

00:02:40.390 --> 00:02:43.590 align:middle line:84%
and safely deploy a
prototype reactor.

00:02:43.590 --> 00:02:47.670 align:middle line:84%
The balance of 2026
into early 2027

00:02:47.670 --> 00:02:50.470 align:middle line:84%
will be focused on
delivery of key components

00:02:50.470 --> 00:02:52.950 align:middle line:84%
for full system
installation, including

00:02:52.950 --> 00:02:56.670 align:middle line:84%
well casing, our reactor
canister and heat exchanger,

00:02:56.670 --> 00:02:59.630 align:middle line:84%
as well as LU
fabrication and loading.

00:02:59.630 --> 00:03:03.910 align:middle line:84%
Pending DOE authorization, we
plan to demonstrate our system

00:03:03.910 --> 00:03:06.830 align:middle line:84%
and apply for a commercial
license in the first half

00:03:06.830 --> 00:03:10.350 align:middle line:84%
of 2027, converting
the same pilot reactor

00:03:10.350 --> 00:03:12.190 align:middle line:90%
to commercial operation.

00:03:12.190 --> 00:03:14.350 align:middle line:84%
We are targeting as
early as that same year

00:03:14.350 --> 00:03:16.950 align:middle line:84%
to seek high-volume
commercial licensing

00:03:16.950 --> 00:03:19.050 align:middle line:84%
for deployment of
multiple boreholes,

00:03:19.050 --> 00:03:21.910 align:middle line:84%
and subsequently
at multiple sites.

00:03:21.910 --> 00:03:26.070 align:middle line:84%
Our goal is to bring new nuclear
capacity online faster and more

00:03:26.070 --> 00:03:29.430 align:middle line:84%
predictably on pace with
modern infrastructure

00:03:29.430 --> 00:03:32.230 align:middle line:90%
and AI-driven demand.

00:03:32.230 --> 00:03:34.930 align:middle line:84%
Nuclear can help meet the
need for more electricity,

00:03:34.930 --> 00:03:39.150 align:middle line:84%
but only if we build it in a way
that works in the real world.

00:03:39.150 --> 00:03:43.390 align:middle line:84%
We are starting with planned
sites in Kansas, Texas and Utah

00:03:43.390 --> 00:03:46.830 align:middle line:84%
inviting people, partners, and
the public to build with us.
