Depth-Sizing Technique for Crack Indications in Steam

2020-3-6 · The nuclear power plants have been safely operated by plugging the steam generator tubes which have the crack indications. Tube rupture events can occur if analysts fail to detect crack indications during in-service inspection. There are various types of crack indication in steam generator tubes and they have been detected by the eddy current test. The integrity assessment should be performed

Checklist - Generator Daily Inspection

Guide to Optimal Steam Generation | STERIS University

With this type of generator, house steam is used to heat water within a system of heat exchangers, with the house steam never coming into direct contact with the water. While this option is the most economical to operate, it is less efficient than an electric steam generator and has a much higher acquisition cost.

GENERATOR TESTING Tests should be done on the generator during the outage to monitor its condition and to ensure that it is in a satisfactory state for return to service, following maintenance. A major overhaul of the generator should be done every 8 years. Details about the tests were provided in Chap. 16. The following

Steam generator mock-up for assessment of inservice

A steam generator mock-up has been assembled for round-robin studies of the effectiveness of currently practiced inservice inspection (ISI) technology for detection of current-day flaws. The mock-up will also be used to evaluate emerging inspection technologies.

2007 ASHRAE Handbook—HVAC Applications (SI) Ch.25

2010-11-3 · Steam lines for primary and reheat steam are typically routed from the steam drum and reheat sections of the steam generator to the steam turbine or process systems. The heat energy and steam process systems impose requirements on the HVAC systems for specific areas of the steam generator building.
