Standard Details


This Standard includes practices that are concerned primarily with the prevention of water damage to steam turbines used for water-cooled nuclear reactor power generation. The practices cover design, operation, inspection, testing, and maintenance of those aspects of the following power plant systems and equipment concerned with the prevention of water induction into steam turbines and the safe removal ofwater from steam turbines and the following associated systems and equipment:

(a) main steam and bypass systems, piping, and drains

(b) turbine extraction systems, piping, and drains

(c) turbine steam seal systems, piping, and drains

(d) feedwater heaters, piping, and drains

(e) turbine drain systems

(f) condenser steam and water dumps

(g) start-up systems

Any connection to the turbine is a potential source of water either by induction from external equipment or by accumulation of condensed steam. The sources treated herein specifically are those found to be most frequently involved in causing damage to turbines. Althoughwater induction into the high- and intermediate-pressure turbines has historically been recognized as the most damaging, experience has shown that water induction in low-pressure turbines can cause significant damage and should also be taken seriously.

This Standard is not intended to impose new requirements for existing facilities retroactively.

Title : Prevention of Water Damage to Steam Turbines Used for Electric Power Generation: Nuclear-Fueled Plants

Publication Date: 10/15/1985 - Complete Document

Description :

These recommended practices are concerned primarily with the prevention of water damage to steam turbines used with light water nuclear fueled steam supply systems which produce nominally dry-and-saturated steam. The practices cover design, operation, inspection, testing, and maintenance of those aspects of the following power plant systems and equipment concerned with the prevention of the induction of water into steam turbines and the safe removal of water from steam turbines and associated systems and equipment:

(a) main steam and bypass systems, piping, and drains

(b) crossaround piping, moisture separator, and reheater piping and drains

(c) turbine extraction systems, piping, and drains

(d) turbine steam seal system, piping, and drains

(e) feedwater heaters, piping, and drains

(f) turbine drain system

(g) condenser steam and water dumps

Any connection to the turbine is a potential source of water either by induction from external equipment or by accumulation of condensed steam.
