I DC f ASH 1hG10ii 20555 Attached are revisions which reflect the incorporation of the Zion Station Chapter 12 errata to the Offsite Dose Calculation Manual (ODCM), as previously approved through Onsite Review and by the NRC.
These changes reflect a correction in a section reference, vent stack instrumentation mode applicability, and TLD values.
The approval by the NRC authorizes the RETS relocation from the Zion Technical Specifications to the ODCM Chapter 12 for Zion.

1 RADIOAOTIVE LIOUID EFFLUENT MONITORTNG INFTRUMENTATION (Cont'd) i ACTION 1 With one of the LDT monitors Inoperable, all LDT releases shall be made through the OPERABLE monitored pathway.
If both monitors are inoperable, effluent releases from the
[
tank may continue, for up to 14 days provided that prior to l
initiating the release:
l 1.
At least two independent samples of the tank's centents are i
analyzed, in accordance with Section 12.3.1.B and l
2.
At least two technically qualified members of the facility staff independently verify the release rate calculations i
and discharge flow path valving; I
i Otherwise, suspend release of radioactive effluents via this pathway.
ACTION 2 With the number of channels OPERABLE less the minimum l
number required, effluent releases via this pathway may l
continue, provided that at least once per shift grab samples are analyzed for gross radioactivity (beta / gamma or isotopic) at a lower limit of detection (LLD) of at least 10" pCi/ml.
ACTION 3 With the number of channels OPERABLE less than the minimum number required, effluent releases via this pathway may i
l continue, for up to 30 days.provided the flow rate is estimated at least once per 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> during actual releases.
Pur.p curves may be used to estimate flow.
