PREFACE
Our volume in the annual review series on this occasion represents a departure from our usual practice in that it serves as a Festschrift for Eugene Wigner. Dr. Wigner has won many honours in his long, wide ranging and distinguished career spanning so many upheavals in civilized life. The editors and the authors, indeed the whole nuclear engineering community, will wish to join in a modest but further acknowledgement of the contributions he has made to nuclear engineering, not least to the morality and professionalism of nuclear engineering in a year that has raised such international concerns over safety.
It suffices to make a bald statement of Eugene Wigner's life and times here, for the first article of the volume is a loving appreciation by his long-time colleague, Alvin Weinberg, an evaluation of his contribution historically during and after the Second World War but equally an account of the philosophy which Wigner provided to the burgeoning profession.
Eugene Wigner was born 17th November, 1902 in Budapest, Hungary and his early schooling is described by Dr. Weinberg. In the upheavals of the 'thirties, he came to the u.S. to start a long association with Princeton, 1930-1971, originally as a part time Professor of Mathematics and with extended periods of leave to further other matters. Thus he was at the Metallurgical Laboratory (Plutonium Project), University of Chicago 1942-45, Director of Research and Development at the Clinton Laboratories, Oak Ridge 1945-46 and returned to Oak Ridge as Director of the Civil Defence Project 1964-65. His honours and distinctions are numerous and the following but a partial list: Franklin Medal, 1950; Fermi Award, 1958; Atoms for Peace Award, 1960; Max Planck Medal, 1961; Nobel Prize for Physics, 1963; U.S. National Medal for Science, 1969; Albert Einstein Award, 1972 and of course the first Wigner Medal, 1978.

viii PREFACE
The balance of our Festschrift is provided by an international authorship who bring us modern accounts of some of the developments initiated by Wigner. One of the curiosities of the linear (neutron) transport theory was the late realisation that it would yield to conventional eigenfunction solution, albeit involving singular integrals and a continuous spectrum of eigenvalues for this integro-differential model. Wigner and Boris Davison had both identified a need to look more closely at the mathematical structure and after the War Wigner found time to work out the details, although these are probably better known now from the devoted work of Case and Zweifel together with their school. In this volume, Professor R. T. Ackroyd and his colleagues in What may be called the English school provides a similar theoretical treatment, using the variational method (another of Wigner's contributions to nuclear engineering) to display the nature of the finite element method as applied today in reactor physics calculations.
The basis of the transport operator in a variational principle is a powerful technique we need not elaborate in the Preface. When this is to be associated with a least squares error measure, then the relation to a non-self adjoint operator is for consideration if the stationary condition is to be a minimum condition having the desired Euler-Lagrange equations. We recall a personal experience when one of us gave an early public paper and the figure rising at the back of the Hall proved to be that of Professor Wigner with a question or rather, a comment; no little occasion to try the nerves of a young lecturer. A propos of Ackroyd's treatment of the A*A operator made thus self-adjoint, Eugene Wigner started by saying "It is a well known fact ... " and then paused, until resuming with his unswerving accuracy "It is well known to some people that every operator can be made self-adjoint".
As Weinberg pOints out, a major thrust of Wigner's philosophy was toward an inherently safe reactor. The volume continues with two up to date accounts of how this philosophy is seen to be accomplished, one from Europe and one from the United States. Dr. Hannerz has given us a description of the PIUS system now offered from Sweden with its ingenious use of hydraulic-thermal locks to provide for automatic supply of cooolant in any excursion. The PRISM reactor described by Dr. Pluta puts more emphasis on the modular nature of the system, the opportunity to dissociate the balance of plant from the nuclear island with its more severe safety require-

ments and the appealing financial implications of bringing a multiple station on line early before interest rates cripple the project.
Surely there are other techniques to exploit to promote inherent safety. One recollects the advocacy of Teller for the underground reactor. The experience of the Swiss with their experimental reactor accident suggests that much may be gained by guaranteeing containment. With modern drilling techniques, a reactor vault 300 m underground is readily constructed. It may also be argued as economic if it obviates a number of features required in any surface containment. The obvious further development is for the selfcontained i.e. fuel manufacturing and reprocessing plant. Here the original interest of the chemical engineer in Wigner may also be reexploited to provide on-line fuel processing rather than the mechanical engineer's route to the nuclear system. There is, by the way, in the U.K., an 8000 MWe generation plant hollowed out within a Welsh mountain, at the Dinorwic pumped storage plant which testifies to the practicability of underground containment of generating plant.
We have already mentioned the introduciton of variational methods or more particularly non-self adjoint perturbation methods in nuclear engineering by Eugene Wigner. It is appropriate therefore to include in this volume of homage a general treatise on the generalised perturbation method that has sprung from the seed Wigner sowed in discussing the Fermi-age equation. Professor Gandini brings to such a review his lifelong interest in the method, showing how it applied to both continuum and discrete models and therefore to a wide range of engineering phenomena. The extension to higher order methods greatly enhances the computational effectiveness of perturbation theory.
Finally the editors wish to acknowledge the benefit the series has had in its Editorial Board of which Eugene Wigner has been a member since the start (in 1962) and of which he is now our Honorary President. Authors and Editors join with Alvin Weinberg in offering this volume in love and gratitude to a physicist, chemist and mathematician, to a distinguished nuclear scientist, engineer and philosopher, Eugene Paul Wigner.
