2. Hg Jet Design Meeting – 15 Nov 2004
Nozzle Constraints
Tilted solenoid has imposed new geometry constraints on the nozzle
Windows are now at bottom of primary containment
Nozzle cannot penetrate primary on end flange, currently shown on bottom

3. Hg Jet Design Meeting – 15 Nov 2004
Flow Issues
High flow in small lines, tight flow path
Direction changes cause several problems
Pressure drop
Vibration
Cavitation
Tube erosion

4. Hg Jet Design Meeting – 15 Nov 2004
Design Issues
Desire mechanically attached nozzle for changeout during cold testing
Need to maximize pipe diameter to decrease velocity and minimize pressure drop
Two supply lines
Minimize number and severity of direction changes
Fairly complex manifold to avoid beam
Possibly supply Hg outside of solenoid in double- wall pipe

5. Hg Jet Design Meeting – 15 Nov 2004
Existing vs new
Show two images – one of existing single tube vs two tubes into manifold with beam hole
