This annunciator window provides visual stimuli to critical response personnel in the event of a vacuum supply failure condition relayed by the CAM vacuum switch at stack 291-2-1.


Components of the 296-2-3 (241-2 sumps and tanks) stack monitor included in the safety envelope are identified in this section. Each component is listed and described, and its design function is explained.

Sample Collection Probe, Flow Splitter, and Piping

The sample collection probe, flow splitter, and piping that make up the sample collection and delivery system is constructed in accordance with ANSI N13.1, 1969. This probe collects a near-isokinetic sample for delivery through the piping and to the sample heads. safety envelope ends at the CAM Vacuum Switch. piping is not included.

The piping included in the Exhaust

Continuous Air Monitor

The CAM provides the primary alert of elevated radionuclide emissions. This allows facility management to respond in a timely fashion to mitigate the release. efficiency must be at least 7 percent and all alarms (high radiation, low count, and failure) must be functional.

The CAM's detection

CAM Flow Rate Indicator

The flow rate indicator is an integral part of the CAM and is used to verify that the flow rate through the CAM meets the requirements specified in SR 3.2.2.1.

CAM Vacuum Switch

The vacuum switch provides an alarm signal to the annunciator panel in Rooms 714 of building 234-52 if the vacuum supply fails. The switch will initiate an alarm due to either high vacuum or low vacuum conditions.

Room 714 Alarm Annunciator Window No. 6 (le)
