'LER 50-321/1979-021, REV. 5 EDWIN I. HATCH NUCLEAR PLANT - HATCH 1 NONROUTINE RADIOLOGICAL ENVIRONMENTAL OPERATING ANOMALOUS MEASUREMENT REPORT
~ SThis i r_eport uihichl supplements ' the previous submittals on LER 50-321/1979-021 iprovides updated data on tritium levels in groundwater samples.taken from flocationsTwhere the average value.during the third quarter of 1983 exceeded
' 3 O.
E4. --pCi/11 which iis :. the = report level for tritium in environmental ' water se:mples according to Table.33.2-3 of the ETS.
There continues to be 'no
'significant11mpact~ on the: public health.and safety due to these readings which
-exceededL the report ' level.
As reported previously, any releases to.
tunrostricted. areas _ are _through the outfalls of the drainage. system;. such
.rsicases / continue ! to be small. ~ and ' result in nonsignificant doses to the lpublic.'
Roportable levels were lfound o'nly at test holes N9B and T3 which are adjacent-to ' each ' other.
Reportable' levels have continuously occurred-at-N9B for over four; years.
'The: tritium' levels at T3 were.. reportable for a few years but then dropped below:the-report level for.a few! quarters.
..Th1i ftritium. levels.found during the ~ third quarter at N9B and T3 are presented inLTable 1.
.It-.is seen that-the levels at N98Lare steadily decreasing-.while those' at T3 Jare increasing.
- The quarterly average levels were 1.85 ES and 3383-E4"pCi/1 at-N98 and T3, respectively.
Dur.ing the '_ second quarter of 1983, reportable. levels were also'found at test hole T18.
>This test' hole was.found to be dry in each attempt to obtain samples _du' ring the third q'uarter.
Thai-Center of Applied ' Isotope' Studies. of the University of Georgia who p3rforms the tritiumE analyses of the groundwater samples has determined that
-thnirM results ' have' been in ' error-due to their failure to account for decay of the tritium standard.
The results obtained in July were approximately 36% too
.high; the' error.' increases about 1/2%:per month.
' -LThs ; results reported. herein-have.-_ been - corrected.
Results reported previously h2Vo accordingly. been _ too high.
Corrective action has been taken by the Conter fort Applied Isotope Studies, such that, accurate results are now being
-cbtained.
