Applicability of 10 CFR 50 Appendix B to Chemicals and Reagents

HPPOS-213 PDR-9111220010

See Interpretative Guide from the IE Manual entitled as above and dated April 1, 1977.

This document states that Appendix B to 10 CFR 50 applies to chemicals and reagents used in primary and secondary systems water chemistry control and analysis. Appropriate controls include testing prior to initial use, and labeling and dating to assure proper shelf-life control.

The purpose of this document was to identify specific criteria that should be used by Inspection and Enforcement personnel for the review and evaluation of licensee management control systems for chemicals and reagents used in primary and secondary system water chemistry control and analysis. 10 CFR 50.34 (b) (6) requires licensees to describe in the Final Safety Analysis Report (FSAR) information relating to managerial and administrative controls to be used to assure safe operation.

In complying with these requirements, most licensees document an FSAR commitment to the requirements of ANSI N18.7. Section 5.3.7 of ANSI 18.7-1972 and Section 5.3.8 of ANSI 18.7-1976 provide general guidance concerning chemical and radiochemical control activities.

The criteria of 10 CFR 50 Appendix B delineate the need for appropriate controls of certain materials. These materials include chemicals and reagents used in primary and secondary system water chemistry control and analysis. These controls may be in the form of administrative procedures which include provisions for storage and use of laboratory and bulk chemicals used in primary and secondary water chemistry control and analysis.

Examples of the type of controls deemed appropriate include:

  1. Testing of purchased and lab-prepared chemicals and reagents prior to initial use to ensure that physical and chemical properties are consistent with purchase specifications or other technical requirements.
  2. Labeling and dating to assure proper shelf life control plus any special environmental considerations that must be maintained during storage.
