Heat transfer and pressure drop performance of herringbone and helical fin fuel elements for uranium/MAGNOX reactors
Technical Report

OSTI ID:4026989
Fuel elements which employ the principle of polyzonal spiral coolant flow described are in use or planned for many gas-cooled reactors, particularly in France and the United Kingdom. The two main types are those with multistart helical finning and herringbone or chevron finning. Typical examples of both types are illustrated, which also give salient dimensions of elements of current interest in Great Britain. The average heat transfer and pressure drop characteristics of many earlier designs of polyzonal fuel element have been reported in detail. This paper has, therefore, been mainly confined to later designs incorporating a larger number of fins for which experimental data has not been published elsewhere.
