A good read in relation to Jodrell Bank is Bernard Lovell's "Astronomer by Chance" Oxford University Press 1992 ISBN 0-19-282949-1.
The mid chapters deal with trials and tribulations of the build and the public accounts committee. Sputnik's arrival in 1957 changed things immediately.
The sunk capital in this instrument is huge compared to the operating costs. I do agree with the sentiment expressed about encouraging young minds.
I think the withdrawal of Jodrell funding as Sir Humprey would say to a minister of the crown, is "courageous". (See "Yes Minister" tv series for context).
From experience I know there's usually no funds to remediate a site , this leaves the opportunity to reinvigorate a system later. This can be painful but if the bones are good then opportunity is present.
Needless to say, preventing closure is obviously the best course of action.
