He also was involved in the quality evaluation of the design phase for one of those installations. In 1998-99 Mr. Norton was part of a three-member senior review panel retained by two west coast utilities to determine the feasibility of decommissioning a jointly owned nuclear facility. The recommendations of that senior review panel were accepted and followed by the utilities. From mid-1994 through 1995 Mr. Norton was retained by the California Seismic Safety Commission to oversee and manage a multi-discipline investigation of the Northridge Earthquake for the State of California to determine adequacy of current building codes, zoning laws, and related infrastructure.

G.L. Plumlee III (Senior Partner & Principal)

Mr. Plumlee has over 37 years of applicable nuclear experience.  This experience began in the Westinghouse Bettis Laboratory program as a civilian instructor (nuclear plant engineer) for the Navy on nuclear submarine and surface vessel power plant operations and testing at the Naval Reactor Facility in Idaho and at the Naval Shipyard in Bremerton, Washington.

Following the Three Mile Island accident in 1979, the Nuclear Regulator Commission (NRC) employed Mr. Plumlee as a Reactor Inspector in Region IV at the Fort Saint Vrain Nuclear Generating Station.  Mr. Plumlee soon advanced to the position of Senior Reactor Inspector at the then nation’s only operating high temperature gas reactor (HTGR).  Later, he advanced to a senior reactor systems engineering position in both the NRC’s Office of Nuclear Reactor Regulation (NRR) and Office of Accident Evaluation and Operational Data (AEOD).

Using this experience, Mr. Plumlee returned to the private nuclear industry sector as a contract senior systems engineer followed by 21 years experience as a licensing engineer and security compliance manager at the Southern California Edison (SCE) San Onofre Nuclear Generating Station (SONGS).  As a contract engineer, Mr. Plumlee developed the equipment history program for the Comanche Peak Steam Electric Station in Texas.  Then, while employed at SONGS, Mr. Plumlee was initially the site’s Licensing Compliance Manager responsible for all regulatory inspection coordination.  Later, Mr. Plumlee as the SONGS Manager, Security Compliance, was responsible for ensuring that SONGS properly implemented the security compensatory measures and new security rules that follow the September 11th attacks.

Following his retirement from SCE in March 2011, Pacific Gas and Electric (PG&E) contracted Mr. Plumlee at their Diablo Canyon Nuclear Generating Station to develop new security procedures associated with their extensive security system upgrades.

Mr. Plumlee later took on a new challenge in the manufacturing industry.  Shaw Modular Solutions (SMS) contracted him as a Quality Assurance (QA) specialist in their Lake Charles manufacturing facility where SMS fabricates modular walls for the new Westinghouse AP 1000-advanced pressurized water reactor.

He has also provided nuclear security consulting services to the Omaha Public Power District.

Currently, Mr. Plumlee is serving as project manager responsible for the NuScale Power new small modular reactor (SMR) security program development.  The challenge is to ensure safety/security is integrated into the new SMR design and to develop a security program that relies on today’s technology to support staffing levels are far below the average experienced at today’s large light water reactors.
