DRESDEN NUCLEAR POWER STATION DOCKET NOS. 50-10, 50-237, 50-249 MEASUREMENTS AND APPROXIMATIONS A. rission and activation gases: The D-1 chimney and D2/3 chimney are

' sampled daily via a grab sample. The D-2 and D-3 Reactor Vents are sampled weekly via a grab sample. The samples are analysed for

, specific isotcpes present in the release using a Ge(L1) spectrometry
l. system. Tritium is collected via a continuous sample on the D-2/3 chimney and via a grab sample on the D2/3 Reactor Vent and analysed using a Liquid Scintillation Counter. Kr-85 is estimated in the D2/3 chimney using a recoil or non-recoil calculation using fission /sec.

plot and the sum of Xe-138, Kr-87, Kr-88, Kr-85m, Xe-133 and Xe-135 j activities.

B. Iodine and Particulate Iodine and particulate samples from the D-1 and D2/3 Chimney and the D-2 and D-3 Reactor Vents are collected for a seven day period. These samples are analysed for specific nuclides present in the release using a Ge(Li) spectrometry system. When particulate samples are not used for reporting the release rate due to management decision that the sample may not be representative, an average of the preceding sample and the following sample is used to calculate the release. A monthly composite is sent to a vendor to be

+

analysed for Sr-89, St-90, and Gross Alpha activity.

C. Liquid Effluents: Prior to a release duplicate grab samples are

' collected from each batch and analysed for gross activity using a gas flow proportional counter. Rad-waste batch discharges are also i analysed for specific isotopes present in the release using a Ge(L1) spectrometry system. A composite of all batches for the month is sent to a vendor to be analysed for Sr-89, Sr-90, re-55, and Gross Alpha. One of the LPCI samples for each month is analysed for specific isotopes present in the releases using a Ge(L1) spectrometry i

system. This sample is sont to a vendor to be analysed for St-89, St-90, re-55, and Gross Alpha activity.
