Functional requirements document for measuring emissions of airborne radioactive materials

Abstract

This document states the functional requirements and procedures for systems making measurements of radioactive airborne emissions from facilities at the Hanford Site.

Conceptual design report for Project W-420, stack monitoring upgrade

“…The velocity profile at the sample location will be measured in accordance with 40 CFR 60 Appendix A, Method 1, Section 2.4, "Verification of the Absence of Cyclonic Flow." Satisfactory contaminant mixing will be demonstrated in accordance with the methods described in WHC-SD-EN-TI-288 (Criddle 1994 …”

“…Performance of the particulate record sampler shall be verified and documented by (in order of preference): 1) a field acceptance test, 2) laboratory wind tunnel testing, or 3) the verified model (Criddle 1994). Performance requirements for the record sampler and sample probe are as specified in WHC-S-0400 (White 1995) and WHC-SD-W420-FDC-001 (Lott 1996).…”

“…The combined return manifold is connected by field piping to the stack downstream of sampling and velocity probes. (Criddle 1994). An existing stack is used when the probe mounting location(s) satisfy the applicable criteria.…”

“…In general, these locations must not exhibit angular or cyclonic flow and must provide acceptable uniformity of contaminant mixing. Specific performance criteria for sample extraction locations is provided by WHC-SD-EN-TI-288 (Criddle 1994). …”

“…Testing (shop or field) will be performed to qualify the sample extraction locations according to the performance criteria of WHC-SD-EN-TI-288 (Criddle 1994). The velocity profile at the sample location will be measured in accordance with 40 CFR 60 Appendix A, Method 1, Section 2.4, "Verification of the Absence of Cyclonic Flow."…”
