About ARS

ARS is a growing, international, and multi-disciplinary company with a strong and diverse client base.  A veteran-owned small business (VSOB), the company has extensive and diverse experience in providing fire protection engineering services to the commercial nuclear power industry, non-reactor nuclear facilities, government facilities, and Highly Protected Risk (HPR) industrial facilities.  ARS consultants provide innovative analysis and solutions in the areas of risk management, safe shutdown analysis, fire probabilistic risk assessment, fire modeling, licensing support, code compliance, and classical fire protection.

Drawing on experience as site fire protection engineers, electrical engineers, licensed nuclear plant operators, shift test engineers, operations managers, fire protection/safe shutdown program owners, utility licensing managers, US Naval officers, research scientists, advanced analysts, project managers, process owners, and consultants, we provide the highest standard of analysis to provide innovative solutions and reduce risk.


Appendix R Solutions (ARS) was founded in 2000 as a veteran-owned small business with the aim of assisting commercial nuclear power stations to develop strategies and programs to comply with the regulations set forth in Appendix R, license conditions, and their licenses to operate a nuclear reactor.

Following the Brown’s Ferry fire in 1975, increasing concerns about the safety and reliability of nuclear power plants in the United States led the Nuclear Regulatory Commission (NRC) to write safety guidelines in 1979, known as Appendix R to Part 50 – Fire Protection Program for Nuclear Power Facilities Operating Prior to January 1, 1979.  At its founding, the mission of ARS was to assist clients to comply with these standards and provide innovative solutions in fire protection engineering.  Since 2000, ARS has expanded its client base to include non-reactor nuclear facilities, government facilities, and HPR industrial facilities and has become an industry leader in risk management for the nuclear power fire protection industry.

ARS has been a major participant in the transition of fire protection programs from the deterministic regulations defined in Appendix R to risk-informed, performance-based regulations under 10 CFR 50.48(c), the development of fire probabilistic risk analyses (FPRA) under NUREG/CR-6850, and the implementation of new fire protection programs.

Following the Great East Japan Earthquake in 2011, which caused the nuclear accident at Fukushima Daiichi Nuclear Power Plant, there has been increasing international concern over the ability to maintain a power plant in a safe and stable condition following an incident.  In the wake of Fukushima, all of Japan’s nuclear plants were shut down and have been undergoing extensive safety inspections.  ARS has supported the post-Fukushima restart efforts of several plants in Japan by conducting safe shutdown analyses in accordance with NEI 00-01, ensuring that one train of systems, components, and structures can remain functional following a fire, by assisting with fire probabilistic risk analyses in accordance with NUREG/CR-6850, and by performing Reactor Oversight Program assessments.

ARS growth has included expanded the companies portfolio to include non-reactor nuclear facilities, highly protected risk (HPR) industrial facilities, and government buildings, structures, and process.
