As a professor of nuclear engineering at the 1st. research reactor at the ARE Atomic energy Authority (ARE-ETRR-1) I have read the book and made some technical presentations to non nuclear engineers and proffessionals. I found the response of the audiance very encouraging to go into more details of this complicated subject. I am thinking of translating the book to the arabic language to be more useful to a wider scope of audiance. I like to know if there is amore recent publication later than 1973. I ejoyed readsing this book and congratulate Mr. Inglis for his effort.
