ABSTRACT:
A modular differential pressure measuring system for a boiling water nuclear reactor pressure vessel is described. The modular pressure differential system includes a plurality of pressure lines having a plurality of pressure line sections. The system also includes a shroud having at least one replaceable shroud section. Each shroud section includes at least one pressure line section which is configured to connect to and disconnect from corresponding pressure line sections in adjacent shroud sections without welding. Additionally, the system includes a reactor bottom head petal section having a shroud support flange and a plurality of bores defining pressure line sections wherein at least one pressure line section of said bottom head petal is configured to couple with a corresponding pressure line section of an adjacent shroud section. The modular pressure system does not require cutting of the pressure lines or pressure line supports for replacement of the replaceable shroud sections. Additionally, the modular differential pressure system does not require welding of pressure lines and/or pressure line supports during installation of a replaceable shroud section.
