Nuclear

AZZ I NLI provides equipment and components for nearly all nuclear plant systems.  NLI’s strength is developing and offering solutions to most difficult equipment challenges facing nuclear plants.  NLI offers solutions to obsolete equipment – whether obsolete means impossible to obtain or simply obsolete technology.  NLI strives to find best in class equipment in the marketplace and qualify it for nuclear use.  NLI will also modify equipment as required to pass qualification testing.

In order to offer such a wide array of equipment and products, NLI partners with many world-class companies such as Ashcroft, Bray, Krohne, Schneider Electric, Trane, and others.  Once known primarily for electrical equipment, NLI has broadened its product offering to include many mechanical products and has become a dominant supplier of HVAC equipment.  From simple pressure gauges to complex diesel generators or entire switchgear lineups, no job is too large or too small.

NLI prides itself as the company that will modify equipment if required for a particular application.  We won’t try to sell you a square peg for a round hole.  We’ll either modify existing equipment to meet your needs or find you what you need.

Electrical

Electrical

NLI made its mark in electrical products and is the nuclear industry’s largest supplier of Class 1E batteries, low and medium voltage breakers and switchgear, and motor control centers.  NLI’s experience with electrical products in the nuclear industry rivals the OEMs. NLI's approach to these products is the key to our success.

Mechanical

Mechanical

NLI is a leading supplier of valves and actuators as well as more complex items such as chillers and HVAC equipment.  Most of our mechanical products are supplied in partnership with other companies, but NLI manufactures the QTRCO line of qualified pneumatic actuators in house. The more challenging the application, the more NLI excels.

Obsolescence

Obsolescence

Obsolescence is a common challenge for today’s operating nuclear plants. The term obsolescence is often used in the nuclear industry to describe equipment and parts that are no longer available for purchase.  NLI’s sole focus is the nuclear industry and to some extent, nearly everything we supply to the operating units is an obsolescence solution.

Post-Fukushima

With the primary goal to protect public health and safety from the inadvertent release of radioactive materials, the NRC’s post-Fukushima Order requires sites to develop a three-phased approach for mitigating beyond-design-basis events. NLI supplied station batteries to half the nuclear sites in North America as well as inverters, switchgear, and other electrical system infrastructure and controls.

Power Uprates

Power Uprate

The competitiveness of nuclear power to coal, gas, and other sources of electrical generation boils down to the cost per kWh. But with so much of a nuclear site’s costs being fixed and many variable costs already reduced to the minimum, the only way to change the profitability equation in the right direction is by increasing the power output. NLI plays a vital role in the power uprate arena.

Standby Power

Standby Power

It is essential that nuclear plants have standby sources of electrical power to run critical equipment as a backup in case there is a loss of normal power. The typical plant has two or three large emergency diesel generators, each capable of supplying sufficient power to place the plant in a safe condition. NLI offers equipment in all areas of standby power, including emergency generators and SBO diesels.
