JUST sFICATIONS FOR REVISION 16 s
Figure B1.0-2 New Figures added to show EMF's and (Page 2 of 2) sampling information to be consistant with additional ventilation system information provided on page B-11a.
Section 83.2.1 Added subsection to allow addition of (Page B-11) system descriptions on page B-11a.
Sections 83.2.2 New Sections added to provide EMF and 83.2.3 setpoint information for existing (Page B-11a) release points as listed on Figure 6.1-3 of McGuire's Technical Specifications.
Section 83.2.4 New Section added to provide EMF (Page B-11a) setpoint information for a proposed gaseous offluent release point. This section will not be used until this release point has been included in McGuire's Technical Specifications n

B3.2.1 IJnit Vent i
As stated in Section B2.2, the unit vent is the release point for the waste gas l
system, containment purge ventilation system, the containment air release and 1
addition system, the condenser air ejector, and auxiliary building ventilation.
l i
Since all of these releases are through the unit vent, the radiation monitor on the unit vent may be used to assure that station release limits are not i
exceeded.
i i
For release from the containment air release and addition system and the containment purge ventilation system, a typical radiation monitor setpoint may be calculated as follows:
i Cg < 5.00E+01/f = 1.79E-03 pC1/ml 2
where:
i j
f = 28,000 cfm (containment purge)
For release from the containment air release and addition system, the waste gas decay tanks, the condenser air ejectors, and the auxiliary building ventilation system, a typical radiation monitor setpoint may be calculated as follows:
Cg < 5.00E+01/$ = 3.51F.-04 pct /ml where:
f = 142,500 cfm (auxiliary ventilation systems) 1 i!O B-ll i

B3.2.2.2 Waste Management Facility (EMF-52)
Ventilation exhaust from the Waste Management Facility is not released through the unit vent and is considered a separate release point. This exhaust is normally considered non-radioactive; that is, it is possible but unlikely that the effluent will contain measurable activity above background. Since the exhaust is continuous, a maximum concentration of gases in the exhaust, which is also the radiation monitor setpoint, is csiculated to assure compliance with release limits. A typical radiation monitor setpoint may be calculated as follows:
C < 5.00E+01/f = 5.95E-03 t
where:
f = 8400 cfm B3.2.3 contaminated Materials Warehouse (EMF-53)
Ventilation exhaust from the Contaminated Materials Warehouse is not released 1
through the unit vent and is considered a separate release point. This l
exhaust is normally considered non-radioactive; that is, it is possible but unlikely that the effluent will contain measurable activity above background.
Since the exhaust is continuous, a maximum concentration of gases in the exhaust, which is also the radiation monitor setpoint, is calculated to assure i
compliance with release limits. A typical radiation monitor setpoint may be O
calculated as follows:
{
C < 5.00E+01/f = 2.94E-03 where f = 17000 cfm B3.2.4 Unit 2 Staging Building (2 EMF-59)
Ventilation exhaust from the Unit 2 Staging Building is not released through l
the unit vent and is considered a separate release point. This exhaust is normally considered non-radioactive; that is, it is possible but unlikely that the effluent will contain measurable activity above background. Since the exhaust is continuous, a maximum concentration of gases in the exhaust, which is also the radiation monitor setpoint, is calculated to assure compliance with release limits. A typical radiation monitor setpoint may be calculated as follows:
e C < 5.00E+01/f a 8.33E-03 where f = 6000 cfm O
