Management and Operations
SN3 provides project and program management services from development of management plans to the implementation of integrated project control systems to the management of multi-million dollar site and facility cleanup and operations contracts. We have developed and implemented facility programs and project management and control systems at the Department of Energy’s (DOE) Grand Junction Office, Hanford, Idaho National Laboratory, Waste Isolation Pilot Plant, Oak Ridge National Laboratory, and Los Alamos National Laboratory. During our tenure as Prime Operating Partner at the Savannah River Site, we have incorporated our best PM practices to lead key SRNS projects including the K-Area Final Storage Vault and Purification Area Vault, Canadian Target Residue Material, and a significant number of activities performed as part of the American Recovery and Reinvestment Act (ARRA) project. At SRS, we manage 5,500 employees, manage 101 active Hazard Category 2 and 3 nuclear facilities, and have met over 2,000 regulatory milestones.
Conduct of Operations (CONOPS)
SN3’s CONOPS Program consists of formal documentation, practices, and actions implementing disciplined and structured operations that support mission success and promote worker, public, and environmental protection. Disciplined CONOPS minimizes the likelihood and consequences of human fallibility or technical and organizational system failures. Our CONOPS Program supports an Integrated Safety Management (ISM) System by providing real techniques and practices to implement the ISM Core Functions of Develop and Implement Hazard Controls and Perform Work Within Controls, and provide feedback for improvements thorough lessons learned.
HII has been at the forefront of the Navy nuclear program for 60+ years, providing state-of-the-art services while operating aging facilities that are in some cases more than a century old. Our owner/operator approach to conducting complex operations within a heavily populated urban area, along with the high expectations of our customer, drives us to develop maintenance and construction programs that ensure safe and compliant operations in a schedule- and profit-driven environment. SN3 has more than 55 years of experience providing technical solutions and expertise to address complex environmental response actions and CONOPS for federal and commercial facilities nationwide, including site remediation, facility decommissioning, environmental restoration; landfills; groundwater treatment; Hazardous, Toxic, and Radioactive Waste (HTRW) management; and regulatory compliance.
New Nuclear Facility Construction
SN3 and NNI employ over 4,800 engineers and technical specialists in a wide range of engineering fields for Nuclear Facilities Construction. They are involved in:

This expertise in structural, mechanical, electrical, nuclear, materials, and environmental engineering provides an unsurpassed background from which to offer professional engineering, design, planning and logistics services for commercial industries and partners through SN3.
Our systems engineers integrate the efforts of each engineering discipline to effectively meet our customer’s needs. At the product level, HII produces optimized systems of systems with proper interfaces. At the system level, engineers bring together component subsystems and ensure that the subsystems function jointly as a system. SN3 employs the entire range of INCOSE systems engineering standards and disciplines, maintaining particular expertise in Requirements Management and Risk and Opportunity Management.
HII planners develop and maintain engineering and design products schedules to support the construction plan. Integrated planning schedules and network planning models identify critical paths, ensure that each discipline is kept in sync with each other, and facilitate the tracking and reporting of cost and schedule performance.
As a leader in the design of highly complex systems, HII personnel utilize state-of-the-art tools and design methods. We have applied 3D product modeling for design and manufacturing for over 25 years.

Lifting & Handling Programs & Crane Maintenance & Certification
SN3 has established procedures and programs for operation and safety requirements for lifting/rigging, use of mobile cranes, overhead cranes, and hoists. In fact, HII’s Newport News location operates the largest crane in the Western Hemisphere: “Big Blue,” a gantry crane capable of lifting 1,050 metric tons – the equivalent of two and a half Boeing 747s.
We ensure our success with strong, detailed work planning that involves all those who will conduct the lifts, and through application of engineered safety methods and procedures. We emphasize safety during all such lifts and conduct nearly a million documented lifts of greater than 10 tons annually.

Facility & Asset Management
SN3’s Asset Management experience is based on performing CONOPS, maintenance, and facility, infrastructure, and program management. We have extensive and well-coordinated inspection and maintenance programs for equipment, systems, and facilities that support all activities including nuclear operations. Our inspection programs are linked to production schedules and future program planning and allow for maintenance activities, system upgrades, and capital projects to be scheduled well in advance, facilitating the funding process for corporate and government budget cycles, and allowing for improvements to work with project schedules. Our significant facility and asset management projects include managing a 550-acre manufacturing and production shipyard at Newport News, VA; managing the management and operations contract at the DOE’s 310-square mile Savannah River Site, and our performance as Prime Contractor under DOE’s Legacy Management Support Services contract.
SN3 parent company, HII, operates, maintains, and enhances more than 1,400 facilities at its six main production and production support sites. Our production operations for building more than 70% of the vessels in the U.S. Navy fleet encompass over 6.6 million square feet of manufacturing area. These operations extend to the maintenance and enhancement of over 180 manufacturing facilities with over 2.9 million square feet of manufacturing area and over 150,000 square feet of analytical space within nine laboratories. Located on the East Coast in Newport News, Virginia, the Newport News Shipyard’s vast and unique facilities span more than 550 acres along 2 miles of waterfront at the mouth of the Chesapeake Bay. HII manages and maintains readiness of the complete set of infrastructure support facilities, including a fire department, clinic, power plant, oil waste and chemical treatment facilities, oxygen plant, propane and welding gas farms, high voltage electrical distribution, telecommunications, high pressure air, compressed air and steam systems, materials test labs, and over 70 nuclear support facilities.
