ST LUCIE PLANT NRC SPIKED SAMPLE RESULTS Nuclide icro-Curies il i-Liter H-3 Fe-55 Sr-89 SR-90 2'4 E-05 1.60 E-05 2.43 E-06
- Denotes that the percent uncertainty for Sr-89 based on Sr-89/90 gross counts minus Y-90 counts makes it too statistically inaccurate to meet--the NRC Criteria of Acceptance.
Reanalysis of the sample would not improve on the poor statistical data since Sr-89 was at least 10 times less than Sr-90 due to decay (5.2 half-lives) at analysis time.
To provide an accurate cross-check for Sr-89, we request a
more current Strontium split sample be provided where Sr-89 has not undergone excessive decay relative to Sr-90.
For information, the Sr-89 activity in the above sample was 1.08 E-05 micro-Curies/milli-liter on January 11, 1987 with an uncertainty of 504, which is not acceptable.
