NRC RULES AND GUIDELINES FOR LICENSE EXAMINATIONS

'During the administration of this examination the following rules ' apply:

. Cheating on the examination means an automatic dental of your application

.and could result in more severe penaltie . Restroom trips are to be limited and only one candidate at a time may leave. You must avoid all contacts with anyone outside the examination room to avoid even the appearance or possibility of cheatin . -Use black ink or dark pencil only to' facilitate legible reproduction .- Print your name in the blank provided on the cover sheet.of the examinatio . Fill in the'date on the cover sheet of the examination (if necessary). Use only the paper provided for answer . Print your name in the upper right-l$and corner of the first page of each

. section of the answer shee . Consecutively number each answer sheet, write "End of Category " as appropriate, start each category on a new page, write only on o_ne side of the paper, 'and write "Last Page" on the last answer shee . . Number each answer as. to category and number, for example,1.4, . Skip at least three lines between each answe ' 11.

ANSWER H.01 (2.00)

NO, it wont. Delayed neutrons behave as a source themselves. When a subcritical reactor has sufficient reactivity, the delayed neutrons are subcritically multiplied. The large number of generations associated with this multiplication effectively holds up the decay rate. The negative period becomes (-80 second [+2.0]

rho = beta eff/1+1ambda tau (p. 11, equation, operator Training Manual)
