NRC Clarification of 0 en Item No.
177 The design description indicates that during start-up there is discharge of the condenser evacuation exhaust to the turbine building.
The turbine building at that discharge location is not enclosed; therefore, the discharge goes to the atmosphere.
In accordance with. SRP 11.5 there must be the capability to monitor and sample the condenser evacuation discharge (hogging) since it is not going to a monitored vent.
~Res onse The concerns identified in Open Item No.
177 include the concerns identified in Open Item Nos.
- 155, 159, and 178.
This combined response addresses all four open items.
The condenser evacuation system is described in Section 10.4.2 and shown on Figure 10.1.0-4.
During normal operation, the condenser vacuum pump discharge is via line 7AE12-9-1 as shown on Figure 10.1.0-4 to the Turbine Building Vent Stack.
The Turbine Building Vent Stack is a common vent stack for discharging to atmosphere the exhaust from condenser vacuum pumps and other ventilation exhausts per Table 12.2.2-2 that do not have radioactivity associated with them.
Monitoring of the condenser vacuum pumps exhaust occurs prior to release to the vent stack (release point 3A for Unit 1 and 3B for Unit 2) by an off-line, wide-range noble gas monitor composed of RE-1TV-3534-1 and RE-1TV"3534-2 at Elevation 286, and RM-1TV-3534-1 at Elevation 240 as described in Section
- 11. 5.2. 7.2. 9.
RE-1TV-3534-1 and RE-1TV-3534-2 are shown on Figure 9,4.4-1.
This figure will be revised to also show RM-lTV-3534-1.
During plant startup, a main condenser vacuum will be drawn with one or both condenser vacuum pumps discharging to atmosphere via vent line 7AE12-19-1 through valve 7AE-B9-1, condenser hogging valve, and via line 7AE12-9-1 through valve 7AE-B3-1 as shown on Figure 10.1.0-4.
Monitoring of the effluent discharge occurs by monitoring the portion of the condenser vacuum pump discharge that flows via the normal operating exhaust path, line 7AE12-9-1, past the radiation monitoring system composed of RE-lTV-3534-1, RE-lTV-3534-2 and RM-1TV-3534-1.
In addition, prior to admitting steam downstream of the mainsteam isolation valves, radiological analyses of steam generator water and main condenser hotwell water will be conducted to determine the appropriate flowpath for the condenser vacuum pump exhaust.
Upon a high radiation alarm, a signal is initiated for closure of valve 7AE-B3-1 and valve 7AE-B9-1 (open only during condenser hogging operations),
opening of valves 7AE-B4-1, 7TV-B3-1 and 7TV-Bl-1 and starting of fan E-79 in the condenser vacuum pump effluent treatment system (see Figures 9.4.4-1 and 10.1.0-4).
The off-line monitor has grab sample capabilities to obtain samples for radiological analysis in the hot lab.
The turbine building has a
common effluent vent stack that includes the exhaust of the condenser vacuum pumps discharge as shown on Figure 9.4.4-1.
The other ventilation exhausts which are discharged through this common stack do not have radioactivity associated with them as shown by Table 12.2.2-2; therefore, the exhaust of the condenser vacuum pump system is monitored just prior to release to the common vent stack (release point 3A for Unit 1 and 3B for Unit 2).
During condenser hogging the vacuum pumps discharge to atmosphere is via a short vent line 7AE12-19-1 through valve 7AE-B9-1 as shown on Figure 10.1.0-4.
System design ensures that a portion of the vacuum pump exhaust during hogging is routed through the normal vacuum pump exhaust path past radiation monitoring system RE-1TV-3534-1, RE-1TV-3534-2 and RM-1TV-3534-1.
Therefore, although radioactive contaminated gases are not expected at plant startup in the condenser, the condenser exhaust during hogging will be monitored by diverting exhaust flow and monitoring it.
A high radiation alarm will initiate hogging exhaust valve closure.
Condenser vacuum pump discharge is sampled as shown on Figure 10.1.0-4.
The off-line monitor has grab sample capabilities and provides grab samples as required for radiological analysis in the hot lab.
Sampling of the condenser is also provided as shown on Figures 10.1.0-3 and 9.3.2-2.
The gland seal condenser system is described in Section 10.4.3 and shown on Figure 10.1.0-4.
The exhaust fans direct effluent discharge to a common, header to line 6AE8-16-1 as shown on Figure 10.1.0-4 which will be monitored by an off-. line gas monitor REM-1AE-3536 (which is existing monitor REM-1TV-3534 on Figure 9.4.4-1).
The monitor will be described in new FSAR Section 11.5-2.7.2.18 and has sample taps for radiological analysis of grab samples in the hot lab.
Figure 10.1.0-4 will be revised to show this monitor.
Appropriate portions of the FSAR will be revised to reflect the above response.
These revisions will include:
Section 11.5.2.5.11 will be revised to reflect monitoring during both normal operating and post accident conditions.
Section 11.5.2.7.2.9 will be revised to specify that the condenser vacuum pump exhaust monitor is an off-line wide range monitor and that it is used during both normal operation and during hogging at startup.
Table 11.5.2-1 will be revised to show the ranges of the noble gas monitors for vacuum pump effluents and for gland seal condenser effluents.
New Section 11.5.2.7.2.18 will be added to describe the gland seal condenser exhaust monitor.
Section 10.4.2, Main Condenser Evacuation System, will be revised to reflect operation of the system in light of the above changes.
Figure 9.4.4-1 will be revised to include radiation monitor RE-1TV-3534-1, RE-1TV-3534-2, and RM-lTV-3534-1.
Figure 10.1.0-4 will be revised to include radiation monitor REM-lAE-3536 and normally open motor operated valve 7AE-33-1.
