BWR Training Manual:
The 100-page
BWR Training Manual can be viewed or printed from the Main Simulator Menu
(Adobe pdf document). The manual chapters and their general contents
are as follows:
Chapter 1 -
Introduction
This chapter provides an overview of the BWR Program and how to use it in
gaining the most out of your learning experience.
Chapter 2 -

loading and control rods, moderator density effects, fuel temperature
effects, power coefficient, fission product poisons), Plant Startup Summary.
Chapters 3
through 7 - Plant Startup Procedures
These chapters provide step-by-step instructions for operating the reactor
from the lowest range of reactor power - the source range - through 100%
power. As you manipulate the controls, the instruction provides the
principles of operation, along with the relevant technology behind each
evolution performed in the simulator.
Chapter 3 - Reactor Criticality - Source Range Monitor (SRM),
Intermediate Range Monitor (IRM), Control Rod Selection and Positioning
Controls and Indicators, Rod Sequence Checkoff Sheet, Rod Sequence Control
System (RSCS), Procedure Steps: Bringing the Reactor Critical.
Chapter 4 Reactor Heatup - Average Power Range Monitor (APRM), Main
Steamline Isolation Valve (MSIV), Temperature Effects on Core Reactivity,
Reactor Heatup Rate Limit, Procedure Steps: Beginning a Reactor Heatup.
Chapter 5 Turbine Startup - Reactor Pressure Control System, Turbine
Generator Controls and Indicators, Rolling the Main Turbine with Steam, Main
Generator Synchronization, Main Generator Loading, Reactor Mode Switch,
Procedure Steps: Turbine Generator Startup, Turbine Trip Demonstration.
Chapter 6 Raising Core Flow - Recirculation Pump Speed Indication and
Control, Affect of Varying Core Flow Rate on Reactor Power, Power to Flow
Operating Map, Procedure Steps: Operating on the Power to Flow Map.
Chapter 7 100 Percent Power - Reactor Feed Pump Controls, Reactor
Water Level Control System, Procedure Steps: Power Ascension to 100 Percent,
Water Level Control Demonstration.
Chapter 8 -
Plant Transients and Accidents
The purpose of this chapter is to demonstrate the plant response to several
abnormal operating transients and accident conditions performed at 100%
reactor power. The demonstrations include:
Plant Transient Demonstrations - Manual Reactor Scram, High Reactor
Vessel Pressure Scram, Low Reactor Vessel Water Level Scram, High Reactor
Power Scram, Reactor Feed Pump Trip and Recirculation Runback, Turbine
Generator Trip, Main Steam Isolation Valve Closure.
Plant Accident Demonstrations - Small Steamline Break Inside Primary
Containment, Scram and Stuck Open Relief Valve (SORV), Design Basis Accident
(DBA).

Reactor Operator Certification
The Reactor Operator Certification process provides a two-part "final
examination" of your plant knowledge and operating ability. If you pass
these examinations (80% minimum), you'll be eligible for a BWR Reactor
Operator Certificate documenting your success.
Written Exam - Consists of of multiple choice questions examining
your knowledge of BWR technology. Answers can be reviewed, and changed if
necessary at any time prior to completing the examination, and an
explanation of each answer is provided prior to exiting.
Simulator Exam - Consists of a hands-on examination testing your
ability to operate the reactor plant. The examination consists of five
objectives corresponding to evolutions previously performed in Chapters 3
through 7. The objectives are achieved through operating the simulator.
During the simulation, as the user maneuvers the plant to establish the
conditions required by the objective, the program will subtract points if
errors are made. When the plant has been brought to the required conditions
for the objective, the user exits the simulation. The program then compares
the plant conditions existing at the time of exit to the objective
requirements. If the requirements have been met, the score for that
objective is added to an accumulating total score, and the next objective is
started.
Certification - Upon successful completion of both the written and
simulator examinations, the overall score is tallied. "Reactor Operator"
certification is awarded for passing both examinations with a combined
average score of at least 80 percent. "Senior Reactor Operator"
certification is awarded for passing both examinations with a combined
average score of at least 90 percent.
Appendix A -
Glossary of Terms
The glossary is provided to assist you in becoming familiar with the
terminology used throughout the manual.
Appendix B -
Quick Reference Guide
The quick reference guide to simulator operation contains all of the
information needed to operate the simulator once the fundamentals are
understood. A functional description of all of the controls and indicators,
as well as detailed listing of the procedural steps used to startup the
plant, are provided.
Appendix C -
Trips and Interlocks
This appendix contains a summary of the various system trips and interlocks
simulated by the program.
Appendix D -
Technical Data
Appendix D provides technical data for the typical BWR plant simulated by
the program. In addition, many of the modeling assumptions used in the
program are provided. |
