MLEA Inc. provides nuclear services to a variety of utility industries across the United States. In recent years, MLEA Inc. engineers have been heavily involved in a number of technical activities related to extended power up-rate and licensing submittals. We have also provided engineering support for many plant modernization and improvement projects. We continue to step up and embrace each new challenge with a track record of success. We see this pattern over and over again with repeat business from our clients.

Over the last eight years MLEA Inc. has been working on the review of new reactor applications submitted to the NRC by various utilities across the US. In addition, our staff has also been working on the construction and licensing requirements for new reactors being built in the UAE.

We continue to strive as an AE service provider focused on solving the challenging problems that occur for all utilities operating nuclear power plants in the US and abroad.

Nuclear Project Overview

Spent Fuel Pool Decay Heat Management

MLEA Inc. designed an Alternate Decay Heat Removal (ADHR) system to supplement the spent fuel pool RHR system during maintenance operations (Cooper Nuclear Station in Brownville, Nebraska).

New Reactor Licensing

MLEA Inc. provided technical evaluations of licensing submittals for the New Reactor Office of the US Nuclear Regulatory Commission, including review of technical submittals for the design certification of the US EPR developed by AREVA.

Extended Power Uprate (EPU)

MLEA Inc. provided consulting and engineering services to support EPU activities for three US Nuclear Reactors (Point Beach Nuclear Plant, Hope Creek Nuclear Generating Station & Susquehanna Steam Electric Station).

Service Water Modification

MLEA Inc. provided guidance and support to the PSEG nuclear design project to install a closed loop cooling water system for Salem Nuclear Power Plant, Units 1 & 2 containment cooling system.

Licensing Support

MLEA Inc. has provided licensing support for a number of nuclear plants addressing degraded and nonconforming conditions for fire suppression systems, RHR system performance under cold shutdown conditions and impacts to the Service Water System resulting from a plant’s automatic response system initiated by LOCA, LOOP or both.


MLEA Inc. conducted Safety System Functional Inspections (SSFI) of diesel generators, emergency ac distribution systems, 125 Vdc distribution systems, emergency service water systems, RHR systems and main steam systems.


MLEA Inc. led the Salem Nuclear Power Plant FSAR Project. The FSAR project integrated a series of new initiatives with several recently completed or ongoing Salem improvement programs related to the plant licensing and design basis. The new initiatives implemented by the FSAR Project included UFSAR reviews, accident analysis input and assumption validations and vertical slice reviews.


MLEA Inc. identified several scenarios where adverse interactions could occur among safety systems due to design modifications or plant conditions at Crystal River 3. Postulated failures of DC control circuits were common precursors to these scenarios. MLEA Inc. performed Failure Modes and Effects Analysis (FMEA) to systematically identify other scenarios. MLEA Inc. developed the FMEA methodology, coordinated electrical evaluations and assisted in the evaluation of system and plant effects.


MLEA Inc. prepared and reviewed numerous 10CFR50.59 Safety Evaluations for various US nuclear power plants.
