PBMR reactor question

["Don Williamson, Jr" <williamson@STUDENTS.WISC.EDU>]

Hello all.



I am helping a middle school student group prepare some information

regarding a debate in class on nuclear power.  They are interested in the

PBMR technology and have done a great presentation so far.  However, I am in

need of help beyond what I know.  I hope someone on here could help me with

this information.



Today the anti's in the class presented some information regarding a

radiation leak in 1985 at the THTR-300 in Germany.  I have found some

information that it was due to a fuel sphere getting jammed in tube.

However, I am wondering where else I could find information regarding this

event or if someone has more knowledge they could forward me.  Was this a

one time event or was this type of jamming commonplace?  How has this been

corrected in the new reactor design?



I appreciate your time and help with this question.  Feel free to respond to

my email off the list to send me the information.



Thank you again.



Don
