TMC Services' engineering services provide stability by assuring that regulatory requirements are identified early and communicated appropriately, and that design, operating and construction constraints are resolved with the regulator and documented as bases for operating permits. TMC Services regulatory experts have integrated teams of designers, operators and safety analysts to develop limiting conditions for operation, surveillance requirements, and action statements to ensure that systems are operated within their approved safety design envelopes. To confirm that systems integration of the design has been successful, TMC Services conducts vertical slice inspections. TMC Services also organizes and participates in readiness reviews, including inspections to confirm consistency between design, regulatory and functional requirements, and the training, maintenance, operating procedures, and as-built condition of the system. TMC Services has experience serving as the interface between regulatory authorities and design, construction, and operating organizations.
