Summary of Recent Activities

Following are brief summaries of some of Dr. Joyner's recent activities. This is not an exhaustive list but is illustrative of the kinds of services he can provide.

Oconee Nuclear Station (ONS) Recent Activities

• September 2005 – present: Working approximately 2/3 time as a System Engineer with the Digital Process Controls Unit at the Oconee Station. Duties are diverse and include participation in the RPS and ESFAS replacement/upgrade project.

• November 2004 – September 2005: Worked with the Power Uprate Project Team that was chartered to determine the feasibility, desirability, cost, schedule and other aspects of performing a MUR Power Uprate on the Oconee Units. He had a broad range of duties that included working with key vendors (Framatome, Shaw/S&W, Caldon and others) to perform the various system reviews necessary to realistically evaluate and plan the Uprate. Also, during this period he assisted with a modification project to install diagnostic instrumentation (accelerometers and pressure transducers) on the newly installed Oconee ROTSGs.

• August 2003 – December 2003: Worked on a conceptual design for an improved auxiliary FW control system for the Oconee units.

• December 1999 – August 2003: Was a member of the Oconee Refurbishment Engineering Team and worked  2/3 time on a variety of tasks including initial scoping of modifications, specification preparation, vendor selection, vendor oversight, software and hardware design reviews, test preparation and other tasks. Projects with which he was involved included main turbine control system replacement, electrical penetrations replacement, RPS/ESFAS replacement, upgrade of the Keowee Hydro Station control systems, Keowee Hydro Station generator exciter replacement and other projects.

• July 1996 - November 1998: Worked approximately 2/3 time with the Oconee Modification Engineering staff on design, installation and testing of a new digital Integrated Control System (ICS) for the three Oconee units. Also provided support for the plant computer replacement project and for smaller modifications.

Recent Activities at Other Stations

• March and November 2007 for the ANO-1 Nuclear Station - Provided two different 40 hour classes for station engineers, trainers and I&C technicians. These classes are descriptively named “I&C Principles, Print Reading Skills and NSSS Control” and “Practical NSSS Control Loops and Implementation Exercises”

• May and June 2007 for the Davis-Besse Nuclear Station - Provided consulting services on a project that will replace the analog Integrated Control System (ICS) with a digital system. Activities included a thorough review and critique of the Project Plan, Project Schedule and Project Specification.

• July 2006 for the Crystal River 3 Station - Was a member of an Assessment Team that performed an in-depth review of a proposed CR 3 ICS Replacement Project.

• March 2004 through September 2004 for the Fermi 2 Nuclear Station - Dr. Joyner performed independent Project Reviews for three modifications in progress at Fermi 2. He also prepared a level 2 schedule, cost estimate and conceptual scope for a main turbine control system upgrade.

• March 2004 for the Davis-Besse Nuclear Station - During plant restart in the late winter of 2004, traveled to the Davis-Besse site on several occasions to assist in resolution of I&C related problems that were delaying return to 100% power.

• Summer 2003 for the ANO-1 Nuclear Station - Dr. Joyner performed an independent pre-implementation review of a modification to the ANO-1 Integrated Control System. That modification was installed in 2004.

• Spring 2002 for the Fermi 2 Nuclear Station - Performed an independent design review of a modification to the main turbine gland steam control system. This modification was successfully installed in 2003.
