Radiation Shielding Engineer

Ocean Atomics • Bethesda, MD

21h • $110,000 - $240,000

About The Position

Ocean Atomics (OA) is an American company designing, licensing, and assembling a standardized nuclear electric power plant and the surrounding support systems for maritime applications. We will install these plants on any vessel built to our nuclear-ready standards, and will provide end-to-end sustainment in our planned nuclear lifecycle dockyard. We will help develop the licensed operators to unlock this new capability for your energy intensive application at sea. To move fast and to lead the creation of this new market, we are leveraging the compact, proven systems enabled by water-cooled reactors.
Our mission
Scale nuclear energy. Power generations.
Our vision
A maritime commons thriving with abundant, economical, modern, and safe nuclear-powered activity — built, serviced, and staffed by re-industrialized American shipyards and people.

Requirements

• Bachelor's degree in nuclear engineering required (advanced degree preferred).
• Experience designing and analyzing radiation shielding for reactor or other high-radiation systems.
• Proficiency with radiation transport codes (MCNP, SCALE, etc.) and shielding/source-term methods (i.e. FW-CADIS).
• Familiarity with shipboard or other space- and weight-constrained installation environments

Responsibilities

• Designs and analyzes radiation shielding throughout the reactor and ship to keep dose rates within limits for crew, equipment, and the public, while developing shielding configurations that can be fabricated, handled, and installed efficiently within the constraints of shipyard construction.
• Design and analyze radiation shielding for the reactor, primary systems, and surrounding compartments using transport, Monte Carlo, and hybrid methods.
• Perform activation, dose-rate, and source-term calculations across operating, shutdown, and accident conditions to verify compliance with occupational and public dose limits.
• Study historical ship and other unconventional shielding solutions and bring applied history into our design.
• Develop shielding arrangements optimized for shipboard installation: modular geometries, manageable component weights, access for handling equipment, and compatibility with build and outfitting sequences.
• Coordinate with our structural, layout, and construction teams to integrate shielding into the ship arrangement and resolve weight, space, and installation trade-offs.
• Document shielding designs, analyses, and as-built configurations, and support design reviews, licensing, and certification deliverables.
