  • MPR Develops Fail-Safe Controls for Critical Mission Equipment

    Chilled Water Automation System

    The Navy needs to improve the survivability of chilled water systems to help prevent vital ship functions from shutting down due to loss of cooling when combat damage occurs. The automation to recover the system from damage needs to be highly survivable. The Navy needed to select an economical system developer with unique expertise in fluid control systems and survivability, and the ability to integrate with the existing shipboard control system.

  • Nuclear Hydrogen Initiative is Recognized for Best Program Management

    Nuclear Hydrogen Initiative Program Management Support

    The Department of Energy's (DOE) Nuclear Hydrogen Initiative (NHI) is a key part of the nationwide efforts to mass produce an energy source that is economical, environmentally safe, and independent of foreign sources. The Nuclear Hydrogen Initiative is developing the technology to efficiently and cleanly produce large quantities of hydrogen using nuclear power as the energy source for the process. Managing the technically and geographically diverse Government and commercial activities that comprise the Nuclear Hydrogen Initiative is a significant challenge. Read More

  • MPR's Smart Valve Technology is Installed In DDG 51 Class Ships and in the Advanced DDG 1000 to Improve Survivability

    Survivable Systems Development and Design

    Several key factors are driving the Navy's need to apply new technology to make ship systems more survivable: -Weapons are more lethal. -Modern mission systems are more dependent on support from integrated ship systems to provide power, cooling and other vital support. -Ship manpower must be reduced to make future operations affordable; this requires moving from manual to automated recovery from damage. Meeting the challenge of creating more survivable systems requires innovative approaches to ship systems survivability. Read More

  • MPR Helps Major DOE Project Start Construction on Track

    Department of Energy Mixed Oxide (MOX) Fuel Fabrication Facility

    Reducing the amount of weapon grade nuclear material in the US and Russia is a key part of reducing the threat of nuclear weapon proliferation. The US and Russia agreed to jointly dispose of tons of nuclear warhead material by "burning" it in nuclear reactors, thereby rendering the material unsuitable for use in weapons. To accomplish this, the warhead material must first be processed into Mixed Oxide Fuel (MOX) that can be used in a nuclear reactor. The design and construction of the MOX Fuel Fabrication Facility (MFFF) for safely processing this hazardous material requires the successful integration of several technical disciplines, including: HVAC, Electrical/Instrumentation and Controls, Seismic/structural, Chemical and safety systems, Glovebox mechanical and electrical design, and Glovebox automation and software design.

  • MPR Designs Solution for Valve In-situ Repair, Saving Plant Over $10 Million, Receiving Top Industry Practice (TIP) Award

    Crystal River Unit 3 Nuclear Energy Complex DHV-3 Repair

    The Crystal River 3 Nuclear Energy Complex, in Citrus County, Florida, was experiencing chronic leakage in an un-isolable valve in the decay heat removal system. The valve is an integral part of the closed-loop coolant system and shutting down the reactor to make the repair would have cost the plant millions of dollars. Repeated unsuccessful attempts were made to repair the valve and prevent further leakage. Read More

  • MPR Recommends ABWR Providing Effective Solution for Nuclear Plant Project Owners

    STP 3&4 Independent Assessment

    When NRG elected to proceed with the STP 3&4 project in 2006, STPNOC hired MPR to prepare an independent assessment of the project as well as the available options for constructing new nuclear power plants. Read More

  • MPR Creates Qualification Prototype for Addressing Digital Equipment

    Generic Qualification of Tricon PLC System

    MPR developed and implemented the program to qualify the Tricon PLC System for use in safety related nuclear applications. The engineering and testing program included environmental, seismic, EMC, and Class 1E to non-1E Isolation. The test program qualified the system chassis, power supplies, processor modules, analog input & output modules, digital input & output modules, relay output modules, and communication modules.

  • MPR Creates First-Of-A-Kind Pump Modification, Saving Millions of Dollars

    HPI Pump Modifications

    Davis-Besse HPI pump modifications to increase tolerance to operation with debris-laden water. Read More

  • MPR Extends Service Efficiently from Short-Term to Long-Term

    Salem Fuel Handling Building (FHB) Degradation

    Leakage was identified in the Salem spent fuel pool liner, exposing the fuel handling building structure to degradation from long-term contact with boric acid. Read More

  • MPR Conducts Large Diesel Engine Extended No-Load Testing to Confirm Operability

    Nuclear Power Plant Emergency Generator

    MPR received a request from a nuclear power plant to conduct a full scale test to demonstrate that its emergency diesel generator (EDG) was capable of operating for an extended period of time at no load. The original equipment manufacturer (OEM) had stated that it was unacceptable to operate its engines for long periods of time with little or no load on the engine generator set. Since the EDG is not required to produce full rated power during most accident conditions, the USNRC was concerned that the engine would not support its long-term plant safety mission. Read More
