Mechanical Design Engineer - HFIR

Background:

The HBRR (HFIR Beryllium Reflector Replacement) project:

ORNL is preparing to replace HFIR’s permanent beryllium reflector, along with other key reactor core components, to sustain and enhance HFIR’s operational performance. This effort requires the disassembly of the reactor and neutron instruments and will result in a period of extended downtime beginning in 2028.

The HBRR effort includes a approximately 4000 sq.ft. expansion to the existing cold guide hall facility as well as upgrades to the thermal and cold neutron instruments. The effort also includes a reconfiguration and expansion of the neutron guide network and instrument layout within the cold guide hall. Extending this guide hall will allow for reconfiguring and optimizing the facility’s cold neutron instruments to significantly improve their performance, develop new capabilities, and provide space to build new instruments.

As part of the HBRR effort, the instrument beam room (thermal instruments) must be fully disassembled and re-installed in conjunction with the beryllium replacement. This effort includes numerous design activities including new designs and evaluation of existing designs.

As an augmented part of the Design Services staff, this role would support the Instrument Engineering Group in their efforts to reconfigure and optimize the instruments in the beam room and cold guide hall located at HFIR.

Responsibilities:

• Performing FEAs on vacuum chambers and must be familiar with FEA modeling and analysis.
• Responsible for developing calculations on vacuum chambers, torque calculations, bellows, lifting calculations, and comparing to code requirements (applicable ASME codes).
• Responsible for providing input into the vacuum specifications.
• Responsible for providing technical review of the drawings and providing markups to be consistent with the technical design.
• CREO experience is preferred but not required. Other 3D modeling software experience may be acceptable.
