ANS 59.51-1976 (N195) PDF

This Standard provides the design requirements for the fuel oil system for diesel-generators that provide standby power for a nuclear power generating station. The system includes all essential equipment from and including fuel oil storage tanks up to the terminal connection on the diesel-engine. It does not include that portion of the fuel oil system supplied by the diesel generator manufacturer which is in accordance with Trial-Use Criteria for Diesel-Generator Units Applied as Standby Power Supplies for Nuclear Power Generating Stations. This definition of scope is intended to exclude only those factory-assembled, engine-mounted appurtances supplied with a diesel-generator unit. Integral tanks are, however, within the scope of this Standard. It also excludes motors, motor control centers, switchgear, cables, and other electrical equipment which is used in operation of the fuel oil system, except to define interface requirements.
The standard provides specific information on requirements for system function and performance, component design and performance, provisions for system and component testing and maintenance, instrumentation and control, and fire protection. It also sets forth other specific design requirements such as safety class, materials, physical arrangement, and applicable codes and regulations.
