Senior NSSS Integration Engineer

Key Responsibilities

• Lead NSSS integration for Alva’s 2TGP and related uprate projects, ensuring NSSS requirements are correctly translated into system design, controls philosophy, and implementation scope.
• Work with Alva’s 2TGP process engineering team, EPC partner, I&C manager, and DuoSync developer to define and manage the NSSS-side requirements needed for integrated plant operation.
• Develop and define operating strategies and procedures for startup, shutdown, step load changes, ramping, and other transient operating conditions relevant to two turbine plant operation.
• Serve as the technical bridge between plant operations, process design, controls development, and engineering implementation for NSSS-related system integration.
• Partner with Alva’s safety analysis team to review safety analysis outputs and determine required plant modifications, design updates, and engineering actions.
• Support engineering definition and review of NSSS-related plant modifications, including containment, ECCS, auxiliary feedwater, and other systems.
• Cover technical interfaces among the utility partner, EPC partner, internal engineering team, and NSSS vendor to resolve design, operational, and licensing-basis issues.
• Review design packages, technical deliverables, and modification concepts to ensure consistency with plant operating requirements, transient performance expectations, and NSSS design constraints.

Qualifications

• Bachelor’s degree in Mechanical Engineering, Nuclear Engineering, or related engineering discipline.
• 10+ years of experience in nuclear power plant operations, systems engineering, design engineering, or plant modification programs.
• Strong background in 4-loop PWR operation and systems engineering, ideally with direct experience supporting plant transients, operating procedures, and system response.
• Demonstrated experience working across NSSS and balance-of-plant interfaces in an operating plant or major plant modification environment.
• Familiarity with safety analysis and the engineering implications of design-basis and transient performance requirements.
• Ability to work effectively across process engineering, I&C, safety analysis, EPC, utility, and vendor organizations.
• Breadth of experience in mechanical design, project coordination, and cross-functional technical leadership.
• Strong written and verbal communication skills, including the ability to lead technical discussions and drive alignment across diverse stakeholders.
• Willingness to travel periodically to utility, partner, and supplier sites as needed.
