Obtain the following information from Attachment 1:

a. Radioactivity Rate (Step 5): mCi/sec b. Offgas Flow Rate (Step 1c): cfm c. Rad Monitor Readings (Step 1b) D11-K601A mr/hr D11-K601B mr/hr 2. Perform the following conve rsion factor calculations:

D11-K601A Conversion Factor Offgas D11-K601A mCi/sec Radioactivity Flow Rate Reading mr/hr x cfm = Rate (mCi/sec) / (cfm) x (mr/hr)

= / ( x )

D11-K601B Conversion Factor Offgas D11-K601B mCi/sec Radioactivity Flow Rate Reading mr/hr x cfm = Rate (mCi/sec) / (cfm) x (mr/hr)

= / ( x )

Detach bottom portion and post on Control Room Panel H11-P601 next to Offgas Log Radiation Monitors Recorder D11-R601.

CONVERSION FACTOR l mCi/sec l mCi/sec Rad Monitor l mr/hr x cfm Rad Monitor lmr/hr x cfm D11-K601A l D11-K601B l THESE CONVERSION FACTORS ARE TO BE USED TO OBTAIN A mCi/sec RELEASE RATE FROM OFFGAS LOG RADIATION MONITORS.

TO USE CONVERSION FACTORS, MULTIPLY FACTOR BY CURRENT OFFGAS LOG RADIATION MONITOR READING (mr/hr) AND CURRENT OFFGAS FLOW RATE (cfm): mCi/sec = FACTOR x MONITOR READING x OFFGAS FLOW*

• Flow as read from N62-R808, O/G Outlet Flow Rec pen labeled Charcoal Unit 1-6.
