My question is:  Does anybody have a contingency plan for disconnecting
a 
clogged hose which is or may be under pressure?  Such a plan would
probably 
involve disconnecting the hose within a containment.  I'd appreciate any 
information on how such events are managed.  

=================================================


In my opinion the transfer of high (and medium) radioactive liquids must
be made with respect to nuclear safety rules. The hose should not be
pressurized when is allowed to be disconnected, the operators
disconnected it in a wrong moment.

I dare to suggest a difference of elevation between the two containers,
the recipient at the higher level, a by-pass for the pump (if not a
turbo-pump), a vane at the recipient's inlet and a good work procedure.

To be sure the hose is not under pressure a T-pipe with a manometer 
somewhere on the hose will do the job.
