Title: Applicability of 10 CFR 50 Appendix B to Chemicals

and Reagents

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.
