SUMMARY

OF CHANGES ODCM Revision 12 1)

The Lower Limit of Detection (LLD) equation on pages 26 and 27 was changed to add " elapsed time period expressions" to accurately account for short half lived radioactive isotopes.

A value of 2.71 was also added to the numerator of the LLd equation to achieve a more accurate value when determining the LLD for short sample count times.

2)

Satellite Met Tower on figure I3.1-1 (pg. 19) was deleted to coincide with NCR 93-0361 (A/R A0770503 Eval 2.)

3)

A reference section and purpose were added.

4) h w REMP maps (figure B1-B4) were added.

5)

Surveillance requirements 3.2.4-2 (pg.29) and 3.3.5-2 (pg. 41) were deleted because they were redundant with surveillance regairements 3.2.4-1 and 3.3.5-1.

7)

The word " OPERABLE" was replaced by "IN SERVICE" in control 3.2.4 and 3.3.5 in order to more accurately define the intent of the control.

ODCM Revision 13 1)

Hot Maintenance Shop Gaseous Effluent diagram was revised to coincide with NCR 94-00004 and current system configuration.

ODCM Revision 14 1)

The LGS annual average meterological dispersion (Chi /Q) value was added for evaluation of the site boundary dose rate due to a Noble Gas effluent release.

2)

An LLD equation was added for grab sample analysis and to include entrained Noble Gases in the liquid effluent LLD spacification.
