Descripción de la vacante

Aalo Atomics seeks a seasoned Criticality Safety Engineer to perform independent criticality safety analyses, review safety basis documents, and lead the Criticality Safety Program at the Aalo‑X campus. You will act as CSO for assigned areas, walking facilities, advising operations, and ensuring compliance with ANSI/ANS-8 standards and DOE requirements.

Qualifications include a B.S. in a nuclear discipline and 8+ years in nuclear criticality safety, with MCNP/SCALE/OpenMC/Serpent experience.

Formación

• Bachelor of Science degree in Nuclear Engineering, Nuclear Physics, Physics, or a closely related scientific or engineering discipline.
• 8+ years of experience in nuclear criticality safety, including the independent preparation and review of criticality safety evaluations at DOE nuclear facilities.
• Proficiency with Monte Carlo neutron transport codes (e.g., MCNP, SCALE, OpenMC, or Serpent) for criticality safety analysis.
• Strong working knowledge of DOE criticality safety requirements, including 10 CFR 830, DOE Order 420.1 Chapter III, and DOE-STD-3007.
• Thorough familiarity with the ANSI/ANS-8 series standards for nuclear criticality safety.
• Experience reviewing and assessing safety basis documents for criticality safety adequacy.
• Demonstrated ability to perform independent criticality safety assessments of facilities, processes, and proposed modifications.
• Strong technical writing and communication skills, with the ability to prepare clear and defensible criticality safety evaluations and technical reports.
• Effective interpersonal skills with the ability to communicate criticality safety requirements to operations, design, and management personnel.
• Knowledge of nuclear criticality safety training and qualification requirements per ANSI/ANS-8.26.

Responsabilidades

• Perform criticality safety evaluations (CSEs) independently in accordance with DOE-STD-3007, including scoping calculations for design, technical guidance, and formal safety basis analyses.
• Check and verify criticality safety evaluations for accuracy, including performing independent calculations and analyses to confirm that all evaluation requirements have been met.
• Perform criticality safety reviews and assessments of existing facilities and planned activities, including facility modifications and process changes.
• Review safety basis documents, proposed safety basis documents, and facility/process modifications for criticality safety implications.
• Oversee and support the implementation of the Aalo Atomics Criticality Safety Program requirements, limits, and controls across assigned facilities.
• Serve as the Criticality Safety Officer for assigned Criticality Control Areas, acting as the facility advocate for criticality safety and liaison between facility management and Criticality Safety Engineering.
• Perform regular facility walkdowns and surveillances to maintain familiarity with operations and verify compliance with criticality safety controls.
• Advise operating personnel and supervision on conformance to criticality safety limits and requirements, and identify when Criticality Safety Engineering consultation is needed.
• Authorize the implementation of new or modified equipment and activities within assigned Criticality Control Areas, ensuring they are covered by active CSEs and the criticality safety basis.
• Participate in the development and approval of facility-specific criticality safety controls, including attending review meetings and concurring with facility criticality controls.
• Provide guidance to operations and facility management on the identification of violations and areas of concern related to criticality safety.
• Support the development and maintenance of criticality safety documentation, including the Criticality Safety Program plan, procedures, and training materials.
• Coordinate with nuclear safety, design engineering, and operations teams to ensure criticality safety requirements are integrated into facility design and operational procedures.
• Support development of recovery plans and emergency response procedures related to criticality safety events.
• Perform or support Unreviewed Safety Question (USQ) evaluations for changes with potential criticality safety implications.
