CAlfiION: Make sure correct set is closed to avoid damaging - hydrogen monitors. 1 5.3.8 Af ter cart is flushed, reset " Active / Inactive" indicator lights to Inactive mode. 5.4 Gross Gas Analysis 5.4.1 Perfonn background radiation surveys in the count room and ensure that the multi-channel analyzer (MCA) is operable. , 5.4.2 Place a Marinelli beaker on the GeLi detector and run a 5 minute background count. Record the % dead time indication. 5.4.3 Af ter the background count, remove the Marinelli from the count cave ,(O and inject 5 microliters of sample into it. Replace on the GeLi and count for one minute using the standard Marinelli Q>T table. Expected l %Q results are approximately 5.0 E - 3uci/cc for Xe-133 at 5% dead time l under negligible background radiation conditions. 5.4.4 Dilution factor when injecting 5.0 microliters into a 4.0 liter Marinelli is 8.0 E + 5. Detennine gaseous isotopes using the following formula: (Printout Activity Gaseous Activity i in uCi/cc ) x (8.0 E + 5) = in Containment

' instead of injecting the 5.0 microliters of sample into a Marinelli - beaker, inject it into a 1.0 liter poly bottle. The bottle may then be counted for gross gas activity at Point Beach in the liter bottle geometry. If this is done, use a dilution factor of 2.0 E + 5 to detennine actual activity in containment. C

5.5.2 Inject 5.0 microliters of the samples gas upstream of the filter cartridge allowing the gas to flow through the Silver Zeolite cartridge. 5.5.3 Remove the Silver Zeolite cartridge from its holder and monitor it for radiation. 5.5.4 Insert..the CESCO WRU Q)T table on the NCA. 5.5.5 R'uin T5 ninute background count on the NCA. 5.5.6 Place the Silver Zeolite cartridge on the GeLi detector and perform a one minute sample count. Activity results will be in uCi/cc times 1.00 E-6. 5.5.7 If the count roon is inaccessible, the cartridge may be sent to 

     @                           Point Beach for analysis. They use an identical geometry for counting f adine samples.
