AFFORDABLE INTERACTIVE 3-D ENVIRONMENTS FOR ENHANCED NUCLEAR LEARNING

While the nuclear power industry is trying to reinforce safety and regain the public’s support post-Fukushima, it is also faced with a very real challenge that affects its day-to-day activities: a rapidly aging workforce. A 2009 Nuclear Energy Institute survey indicates that 38% of the nuclear utility workforce is eligible to retire by 2014, leaving the US nuclear industry alone with about 21,600 new workers to educate and train[1]. The industry must also take into account non-retirement workforce attrition, which will account for a 10% reduction of the current workforce also by 2014[1]. In Canada alone, it is estimated that 65% of all power industry workers are over 40 years old and almost 40% are within 5 years of retirement[2]. For New Nuclear Build (NNB) countries such as Vietnam and the UAE, the challenge is even greater: developing a completely new workforce.

COMPACT I/O SOLUTIONS

L-3 MAPPS has been using compact input/output (I/O) solutions on recent full scope simulators and simulator I/O system replacements. This paper looks at Orchid® IO and describes the wide variety of applications where this technology can be utilized.

The input/output (I/O) system is a critical part of any power plant simulator. This system is responsible for relaying operator actions to the simulation and provides the operators with the visual cues (indications and alarms) required to operate the plant. It is essentially the data link between the simulation server running the plant models and the simulator’s main control room panels.

FUKUSHIMA DAIICHI NPP ACCIDENT. ARE THERE CONSEQUENCES FOR NPP SIMULATORS?

A devastating earthquake and tsunami resulted in severe damage at the Fukushima Daiichi nuclear plant in Fukushima Prefecture, Japan just over a year ago. There has been extensive media coverage on this topic. In this paper, we explore the potential consequences of the accident for nuclear power plant simulators.

SIMULATOR CONFIGURATION MANAGEMENT

Do you know where your sources are? Did you ever hear somebody say “gosh, it used to work” and say to yourself “exactly when?” Do you dread the answer to the question “what’s new?” Welcome to a world without software configuration management (SCM). SCM is one of the most important, yet arguably least visible discriminators in the Orchid® environment. This paper summarizes the state of the art for SCM for power plant simulation software.

SIMULATORS FOR NPP ENGINEERING

Full Scope Simulators (FSS) have long been an indispensable part of the licensed training program for nuclear power plant control room operators. Traditionally relatively complex and time-consuming to create and validate, and inextricably linked to the design and operational data of the reference plant that they reproduce, simulators have typically been planned as a single deliverable occurring relatively late in the plant design process. As a complete, integrated dynamic representation of the behaviour of a plant’s process and control systems in their various states of operation, upstream simulation’s value is gradually being recognized for non-traditional applications such as initial learning, procedure development and verification, design verification and Human Factors Engineering. Nev­ertheless, the structured integration of simulation into the planning of the power plant design and training cycle has been somewhat slow. This paper looks at the opportunities for simulation in the entire plant life cycle and includes examples of experience from recent L-3 MAPPS projects in which simulation has played a wider role.

AUTONOMIC CONTROL SYSTEM UTILIZING SMART VALVE TECHNOLOGY

As the level of integration across and between shipboard systems has increased in recent years, there has been greater emphasis on strategies to improve situational awareness, survivability under damage conditions, crew reduction initiatives, Damage Assessment, and Damage Action Management System (DAMS) as well as agent based automation. The above objectives necessitate consideration of an Autonomic Control System with improved intelligence that includes autonomous decision making by hardware with embedded intelligence. Furthermore, to increase survivability, consideration must be given to continued operation of the intelligent agents independent of the Integrated Platform Management System (IPMS), its high level automation hardware/software and its related data communication networks. In this paper, the authors present the application of an advanced Autonomic Control System (ACS) utilizing smart valve technology in the Chilled Water System and Fire Main System to provide highly survivable services critical to the operations of the ship’s combat systems as well as Damage Control Systems.

NEW GENERATION OF CONDITION BASED MAINTENANCE (CBM) FOR MARINE APPLICATIONS

The new generation of Surface Ships and Submarines for the Republic of Korea Navy (ROKN) includes a larger number of vessels with an ever increasing level of automation and advanced machinery. Furthermore, the latest specifications for the ROKN Naval vessels require special consideration for a detailed Integrated Logistics and Life Cycle Support including Availability, Maintainability and Reliability assessment. This necessitated comprehensive assessment of preventive, planned, onboard and shore based maintenance by Special and Naval Shipbuilding Division of various Korean Shipyards (the ship design authority), the Defense Acquisition Program Administration (DAPA) and the ROKN’s Logistics Command Group. Consideration of a highly enhanced Condition Based Maintenance (CBM) management system will improve mission critical systems availability and will result in improved future operations as well as lower Whole Life Cost (WLC). A proven, cost effective, reliable and advanced CBMis presented to meet the above challenges. This paper presents highly advanced CBM capabilities, scope and functionalities that is suitable for On-board as well as for Land-based applications. Of special value are the Fleet Maintenance and Enterprise Maintenance proven concepts that can be equally considered for surface ships, submarines, semi Naval and mission critical Commercial vessels. The presented CBM is fully integrated with the L-3 MAPPS Engineering Control System (ECS).
