11.5.5.4.4 Gas Analysis-Gas Chromatography A gas chromatograph will be used to measure hydrogen and oxygen concentrations in containment atmosphere and dissolved gas samples.
i a.
Dissolved hydrogen concentratidns - - An accuracy of +10 percent can be expected over the range of concentrations from 50 to 2000 cc/Kg.
Below 50 cc/Kg, the accuracy will be +0.05 cc/Kg.
Gas chromatography has been successfully demonstrated for the determination of hydrogen in THI-2 post-accident gas samples.
b.
Dissolved oxygen concentrations - - Dissolved oxygen I
will be measured indirectly usinn the residual hydrogen l
method of analysis.
Using this method, dissolved oxygen concentration is verified to be less than 0.1 ppm by measurement of positive hydrogen residuals of greater than 10 cc/Kg.
(.
11.5.5.4.5 Determination of Extent of Core Damage e sswent Ahproceduretoassesstheextentofcoredamagebasedon rMdionuclide concentrations and other parameters has been prepared by GE INS W 11.5.5.4.6 Storage and Disposal of Sample Short-term sample storage areas will be provided in the chemistry laboratory and counting room facilities.
An area for long-term storage of the samples will be designated at a later date.
Low level wastes generated by the chemistry procedures will be flushed to radwaste.
Ultimate procedures for disposal of the samples will be determined later; however, after a sufficiently long decay period, the activity levels will be significantly reduced.
Thic will ease exposure problems during disposal.
l l
11.5.5.4.7 System Testing and Operator Training 1
(
Equipment used for post-accident sampling and analyses will be l
calibrated or tested approximately every six months.
At least l (
five members of the onsite organization will participate in sampling operations within any 6-month period.
