ENCLOSURE 2 Braidwood Unit 2 Primary Coolant Specific Activity. Analyses I
l There was one occurrence during 1994 in which the primary,
1 coolant. specific activity exceeded the. limits of Technical Specification 3.4.8.
The first sample exceeding the limit occurred at 1835 on April 5, 1994, following a reactor' trip approximately three hours earlier.
The total time duration
)
i when the specific activity of the primary coolant exceeded.the
~
radioiodine limit was 9 hours1.041667e-4 days <br />0.0025 hours <br />1.488095e-5 weeks <br />3.4245e-6 months <br /> and 40 minutes.
' to this report contains Braidwood Unit 2 Power I

i -to this report.is a graph of results of the last j
isotopic analysis for radiciodine performed prior to exceeding the limit, including results of analyses while exceeding the.
limit and analyses results after radioactivity was reduced to less than the limit.
Also contained on the graph are other radiciodine isotope concentrations in microcuries per gram as a function of time for the duration of thel specific activity above the steady-state level, and sample results following retu;n to less than the specification limit.
A chart is included with this enclosure detailing specific sample results versus reactor power and clean up system flow..
