1. The subject paragraph of section 9.1 will be replaced with the following paragraph:

^

Safety-related identifications for quality assurance I are determined from safety analyses. Although sev- l eral systems such as the reactor safety and pro-tection system, engineered safety features and ra-diation monitoring systems are important to safety, '

only one reactor component, the fuel element clad-ding is identified as safety-related. The quality assurance program is not applied to routine reactor operations and surveillance activities but shall be implemented for nonroutine activities determined to be safety related in nature or affecting safety related components. Activities shall include de-sign, construction, testing, modification and main-

tenance of safety related items. Other components related to safety limits, limiting conditions for operation and design features, as identified in
f. technical specifications, will apply only those elements of quality assurance necessary to es-tablish reliable performance of the intended structure, system or component function. The following table lists the components subject to the quality assurance program or selected sec-tions of the program.

"The checklist or approval shall be incorpor-

' .ated in the table format for the acceptance of each specified quality assurance element by the facility supervisor."

4. Rephrase the first paragraph last sentence of section 9.2.1 to read "...., that is knowledgeable of the design criteria and is informed of the quality requ'irements."

Rephrase the first paragraph last sentence of section 9.2.2 to read "..., that is knowledgeable of the procure-ment specifications and is informed of the quality require-ments."

5. In section 9.3.1 delete the word " Maintenance" as the first word of the last sentence of the first paragraph.

Replace the last paragraph of section 9.3.1 with

" Procedures shall provide for identification of inspected and tested' items. Provisions shall be made=to clearly identify nonconforming items from conforming items. In situations that inspections are not' advantageous a descrip-tion shall be provided for monitoring actions."

Add the following paragraph to the end of section 9.3.1:

" Procedures shall be~ written for in service inspections of safety-related structures, systems or components."

6. Replace the last sentence of section 9.3.4 with "The disposition of nonconforming materials will be docu-mented."
7. Add the.following section:

9.3.6 Experimental Equipment. Design, construction, modification, inspection, testing and maintenance of experimental equipment shall be subject to this quality

- assurance program to the extent that these activities are safety related.

< 8. Add the following section:

9.3.7 Replacements, modifications or changes. Insofar as possible, the replacement, modification, or change to structures, systems or components with a safety-related function shall be documented as meeting the requirements i
