MECHANICAL SCIENCE

ABSTRACT

The Mechanical Science Handbook was developed to assist nuclear facility operating

contractors in providing operators, maintenance personnel, and the technical staff with the necessary

fundamentals training to ensure a basic understanding of mechanical components and mechanical

science. The handbook includes information on diesel engines, heat exchangers, pumps, valves, and

miscellaneous mechanical components. This information will provide personnel with a foundation

for understanding the construction and operation of mechanical components that are associated with

various DOE nuclear facility operations and maintenance.

MECHANICAL SCIENCE

OVERVIEW

The Department of Energy Fundamentals Handbook entitled Mechanical Science was

prepared as an information resource for personnel who are responsible for the operation of the

Department's nuclear facilities. Almost all processes that take place in the nuclear facilities involve

the use of mechanical equipment and components. A basic understanding of mechanical science is

necessary for DOE nuclear facility operators, maintenance personnel, and the technical staff to

safely operate and maintain the facility and facility support systems. The information in the

handbook is presented to provide a foundation for applying engineering concepts to the job. This

knowledge will help personnel more fully understand the impact that their actions may have on the

safe and reliable operation of facility components and systems.

The Mechanical Science handbook consists of five modules that are contained in two

volumes. The following is a brief description of the information presented in each module of the

handbook.

Volume 1 of 2

Module 1 - Diesel Engine Fundamentals

Provides information covering the basic operating principles of 2-cycle and 4-cycle

diesel engines. Includes operation of engine governors, fuel ejectors, and typical

engine protective features.

Module 2 - Heat Exchangers

Describes the construction of plate heat exchangers and tube and shell heat

exchangers. Describes the flow patterns and temperature profiles in parallel flow,

counter flow, and cross flow heat exchangers.

Module 3 - Pumps

Explains the operation of centrifugal and positive displacement pumps. Topics

include net positive suction head, cavitation, gas binding, and pump characteristic

curves.

Volume 2 of 2

Module 4 - Valves

Introduces the functions of the basic parts common to most types of valves.

Provides information on applications of many types of valves. Types of valves

covered include gate valves, globe valves, ball valves, plug valves, diaphragm

valves, reducing valves, pinch valves, butterfly valves, needle valves, check valves,

and safety/relief valves.

Module 5 - Miscellaneous Mechanical Components

Provides information on significant mechanical devices that have widespread

application in nuclear facilities but do not fit into the categories of components

covered by the other modules. These include cooling towers, air compressors,

demineralizers, filters, strainers, etc.

The information contained in this handbook is not all-encompassing. An attempt to present

the entire subject of mechanical science would be impractical. However, the Mechanical Science

handbook presents enough information to provide the reader with the fundamental knowledge

necessary to understand the advanced theoretical concepts presented in other subject areas, and to

understand basic system and equipment operation.
