It is suggested that/the tangential exposure tube that passes underneath the reactor always be loaded witha neutron absorbing "rabbit" which can be made to stop directly under the reactor to provide aadditional emergency shut down action except when it wis being used for a specific "rabbit" experiment. A boron loaded "rabbitt" should be rather easy to construct. It would of course have to be very carefully sealed so as to minimise any possible dispersal of boron that would reduce the reactivity of the reactor unintentionally.
