Nuclear Chemistry System Engineer

You will own the chemistry of SEALER's fluid systems, from the molten lead in the primary loop to the water-steam chemistry on the

secondary side. You will define the chemistry envelope in which the plant operates and help develop the systems, instrumentation,

and operational strategies that keep it there.

The role sits at the intersection of chemistry and system engineering. You will work closely with our Materials team to ensure

compatibility between coolants and structural materials, and translate chemistry requirements into practical engineering solutions

for oxygen control, impurity management, water chemistry, and cover gas systems.

• Define chemistry requirements for the primary lead loop and secondary water-steam systems, in close collaboration with the

Materials team.

• Develop the systems and instrumentation used to monitor and control chemistry, including oxygen control, impurity management,

water chemistry conditioning, and cover gas systems.

• Work with the Nuclear Waste System Engineer on chemistry-related inputs such as polonium, activation products, and impurity

streams.

You will join Blykalla's Fluid Systems Engineering Team and report to the Manager of Fluid Systems Engineering. You will work

closely with our Materials, Nuclear and Safety, and Test and Validation teams, as well as with external partners working on lead

chemistry and materials.

You are an experienced chemist or engineer who enjoys turning complex chemistry into practical engineering solutions. You are

comfortable working across disciplines and taking ownership in an environment where both the technology and the organisation are

developing quickly.

• More than 5 years of professional experience in industrial or nuclear chemistry, ideally involving coolant chemistry, corrosion

control, or high-temperature chemistry.

• Strong understanding of high-temperature chemistry, corrosion mechanisms, and interactions between coolant chemistry and

structural materials.

• Prior involvement in reactor coolant chemistry for a nuclear plant (LWR primary or secondary chemistry, CANDU heavy water

chemistry, etc.).

Take the chance to work at the forefront of a new generation of nuclear power. Join Blykalla as a Nuclear Chemistry System

Engineer and help develop the systems at the heart of SEALER.

We are proud to foster an inclusive workplace free from discrimination. We strongly believe that diversity of experience,

perspectives, and backgrounds creates a better environment for our employees and a better product. We encourage everyone to be

part of changing the way the world thinks about power supply.
