~.

If H2 up to 10t?

not, why not a higher value than 10t?

Should the guide indicate a forthcoming need or interest in a better means of predicting what isotopes were released at what rate, when, 2.

What if a serious accident leads to a loss of containment integrity?

capability is expected for the 100 channel gama ray spectrone the containment?

Will the gamma ray spectrum measurement atmosphere? How much iodine?

be able to do this? Will it need a sampling procedure? If so, will it Could one get continuous or very be automated, tested, reliable, etc.

one would use containment pressure and the detailed ra measurements to say what leaked and when?

Will radiation level in coolant be measured using the regular let-down cooling line? Does this leave containment? May it be isolated when 3.

you want to know about this parameter?

Is there adequate infomation provided on the specifics of any radiation gettinc into the control room or other vital areas for operator action 4.

(e.g., Diesel building)?

In high range radiation in containment, how many positions are needed?
