Method and apparatus for a riser pipe repair with compression

A riser pipe repair installed on a riser pipe, comprising:

• a first collar attached to a straight portion of a riser pipe of a boiling water reactor (BWR) jet pump assembly above a riser brace;
• a first and second upper/inner support column and a first and second upper/outer support column attached to the first collar;
• a second collar attached to the straight portion of the riser pipe below the riser brace;
• a first and second lower/inner support column and a second lower/outer support column attached to the second collar;
• inner brace supports slideably attached to the inner support columns and the riser brace yoke, the inner brace supports being connected to the yoke via yoke bolts;
• outer brace supports slideably attached to the upper/outer support columns and the lower/outer support columns;
• ratchet bolts connecting the brace supports to each respective support column, the brace supports and respective support columns configured to axially compress the straight portion of the riser pipe by applying an axial compression force in a direction running along a longitudinal length of the straight portion of the riser pipe as the ratchet bolts are tightened.
