Focused Solution Delivers Support for Standard Nuclear Performance

Model (SNPM)

MRO Software (Nasdaq: MROI), the leading provider of strategic asset management solutions, today announced the availability of MAXIMO Nuclear(R), the next-generation asset management solution for the Nuclear energy industry.

MAXIMO Nuclear is part of MRO Software's industry solutions program. This program delivers targeted solutions to support specific industry requirements delivered on the Company's web architected, asset management platform, MAXIMO. Working with The Nuclear Energy Institute (NEI), the Company's Nuclear Energy Advisory Council, which includes leading industry experts, customers and partners, MRO Software is delivering deep functionality required to support key processes in the Standard Nuclear Performance Model (SNPM).

Along with support for modern work, asset, and supply chain management processes, MAXIMO Nuclear uses standardized technologies as part of its architectural platform. This platform enables customers to recognize significant cost savings over older, capital-intensive, client-server and mainframe systems, while taking advantage of security and scalability to deliver an enterprise solution. The modern architecture also allows customers to consolidate many disparate systems and databases for improved efficiency and reduced risk. MAXIMO provides robust configuration capabilities to support the on-going requirements dictated by regulatory agencies and business operations. This flexibility allows for continuous improvement in the pursuit of operational excellence.

"We are excited to be working with MRO Software, and other members of the nuclear energy industry, to continue the progress of operational excellence achieved over the past several years," said Todd Haberland, Manager, Nuclear Production, Detroit Edison-Fermi 2 Nuclear Power Plant. "With MAXIMO Nuclear, we saw the ability to further implement core NEI SNPM processes and KPI's which leverage INPO and other nuclear industry standards and benchmarks. As a nuclear power generator committed to continuously improving our performance, we need a work and asset management system that provides functional value from the top to bottom of the organization, ease-of-use focused on improving human performance and efficiency; all the while adding to our dedication towards a strong nuclear and personnel safety culture. We are confident that MRO Software's MAXIMO Nuclear solution will allow us to improve the pace towards achieving our operational and financial performance goals at Fermi 2."

As with all MAXIMO solutions, MAXIMO Nuclear delivers a framework for integration in a variety of modern methods, including packaged integration for primary ERP and scheduling products.
