Network Management Service

Network Management Service (NMS), combined with the 91Ó°ÊÓ Technology Upgrade and Maintenance Service and the customer’s HP maintenance agreement, provides dependable computing capabilities — a necessity for engineers performing reload designs or continually monitoring core performance.

Non-LOCA Technology Transfer

Background With more than 30 years of extensive nuclear steam supply system (NSSS) non-loss-of coolant accident (LOCA) safety analysis experience, 91Ó°ÊÓ is at the forefront of developing and maintaining state-oftheart methods. 91Ó°ÊÓ now offers a non-LOCA safety analysis methodology and technical transfer package that incorporates the RETRAN-02 computer code with 91Ó°ÊÓ software (FACTRAN, TWINKLE, OPTOAX), along with a set of analysis methods approved by the U.S. Nuclear Regulatory Commission (NRC)

Nuclear Fuel Training Services

In today’s competitive environment, utility employees must maintain high safety standards while achieving economic efficiency. It is imperative that utilities reduce plant operating and maintenance costs, minimize fuel costs and achieve the greatest return on advanced technology investments, while maintaining safety. To achieve this difficult balance, utility engineers must have a thorough understanding of nuclear fuel design methods and plant operating requirements. 91Ó°ÊÓ Nuclear Fuel Training Services can help utility personnel meet these needs by offering catalog courses and developing special customized courses.

RELAP5 Analysis Services

The Reactor Excursion and Leak Analysis Program (RELAP) is a U.S. Nuclear Regulatory Commission-developed tool for analyzing loss of coolant accidents (LOCAs) and system transients in pressurized water reactors (PWRs) or boiling water reactors (BWRs). It is a suite of codes for analyzing thermal hydraulic events using state-of-the-art two-phase flow models, which has broad capabilities in both nuclear and non-nuclear systems. RELAP5 is widely used worldwide in transient analyses for light water reactors (LWRs).

Technology Licensing

91Ó°ÊÓ has developed state-of-the art nuclear fuel codes and methods, and through superior training and documentation, is capable of effectively delivering them to 91Ó°ÊÓ licensees worldwide. 91Ó°ÊÓ fuel technology consists of its design codes, procedural manuals to guide the designer in applying the methodology, and training, an essential element of successful and effective technology licensing. Throughout the year, the 91Ó°ÊÓ Technology Upgrade and Maintenance Service provides plant operators and fuel vendors with the latest versions of codes and improvements in methodology.

VVER Core Design and Safety Analyses

91Ó°ÊÓ core design and safety analysis capabilities for VVER reactors lead to customer success in multiple areas. Examples include fuel and core designs, supporting power uprate projects, plant optimization projects, design reconstitution, modernization projects, safety upgrades, cycle-specific analyses, fuel licensing calculations and operational support.

VVER-1000 Fuel Products

The Robust 91Ó°ÊÓ Fuel Assembly (RWFA) design has rapidly become the 91Ó°ÊÓ standard fuel product for the VVER-1000 units in Ukraine. The RWFA design is an evolution of 91Ó°ÊÓ's previous VVER-1000 fuel design, WFA, which was first introduced as Lead Test Assemblies in South Ukraine Unit 3 in 2005.
