Abstract

The orifice establishment which is improper does to change the entity differential pressure and occurs an error in flow measurement data. Because of this, the thermal power of nuclear power plant could be evaluated excessively and the safety margin could be decreased. In this paper, characters of orifice which is established abnormally was investigated. Specially, the orifice plate which is established in opposition case was modeled and analyzed. Finally, 14.4% was lowly measured differential pressure, when being established in the resultant opposition. And this result with EPRI and NRC experiences was similar.
