PURPOSE:
To establish a procedure for classifyin systems, structures, i
subassemblies, components, and design characteristics so as i
I to estaolish the degree of quality assurance activitj related
- {
to their manufacture, erection, installation, maintenance, or in-service inspection, j
GENERAL REQUIREMENTS:
1.
Classification of systems, subsystems, components, and l
design characteristics shall be confined to two categories,,
defined as follows:
l l
QA Class I:
Those slant structures, systems, subsystems, f
1 and equipment which are necessary to assure l
the integrity of the reactor coolant pressure !
.l boundary, t'he capability to shut down the j
reactor and maintain it in a safely shutdown i
I condiLion, or the capability to prevent or i
mitigate the consequences of accidents which i
could result in of fsi te exposures in excess l
of 10 CFR Part 100.
The system may be re-l l
dundant or nonredundant in nature (i.e.,
I I
reactor coolant system) and includes such things as structures, containments, and control systems used to meet regulatory requirements, j
]
QA Class II:
Those plant structures, systems, subsystems, components or equipment, which are not QA
[
Class I, that as a result of being defective l
could cause a safety hazard, an unscheduled reduction in unit output or major equipment i
j damage.
These systems are normally located in the balance of plant (80P).
l 2.
Nuclear Engineering shall determine the classification of I
systems, subsystems, components, or design characteristics l-set forth in drawings and specifications.

.I QUALITY ASSURANCE PROCEDURE NO. 3 of the Nuclear Regulatory Commission (NRC) Quality Assur-ance Criteria for Nuclear Power Plants.
Criteria are set
-forth in the Federal Register, Vol. 40, No. 13, January 20,.1975 (10 CFR Part 50, Appendix B).
4 Quality Assurance participation on Rancho Seco Unit No. 1 is required on those items that have QA Class I designa-tion.
5.
All materials and work which come under the regulations of-ASME Codes will be subject to the quality assurance-requirements of'this manual as follows:
a.
Modification to Existing Systems:
1)
All ASME Section III Nuclear Vessels Class A&B, USAS B31.7 Class I, and Pump and Valve Code Class I materials will be subjected to QA Class I requirements.
2)
All Section III Nuclear Vessels. Class C materials will be subjected to QA Class II requirements as a m nimum.
3)
All piping under 831.7 will be subjected to QA Class II reTuirements as a minimum.
4)
All items coming under th.e Nuclear Pump and Valve Code will'be QA Class II as a minimum.
b.
Installation of New Systems:
The QA Class will be determined by Nuclear Engineer-ing.
PROCEDURE:
1.
In conjunction with design review, as noted in Quality Assurance Procedure No. 3, the Manager of Quality Assur-ance will audit the quality classification listing.
2.
Classification of characteristics must be accomplished on all classified systems, subsystems, and components.
This classification shall be based on:
a.
An assessment of each design characteristic in a failed or defective condition to determine whether the resulting effect is Class I or Class II in nature.
3-2
p_
i
?
-QUALITY ASSURANCE PROCEDURE'NO. 3 b.
An analysis of specified ASME Code requirements.
This determination is made by the engineer based on his knowledge of the material or equipment.and represents his Ljudgment of what design dimensions, performance. require-ments, or special tests are critical from the standpoint of the quality class definitions.
3.
Classification of characteristics will be indicated in specifications and purchase requisitions.
The General Requirements for Quality Assurance, Figure 3-1, will be used as guidance for assigning the minimum desired quality requirements.
4 Commercial Grade Items will exist under the classification of QA Class I provided they fall under the following conditions:
a.
Manufactured.for use by general industry, and b.
Normally manufactured prior to receipt of a purchase order by the supplier, and
' Manufactured to national standards ~or by processes c.
that are highly gepetitive or automated, and d.
Can be ordered from the original manufacturer / supplier on the basis of specifications set forth in the manu-facturer's published product description (sales cata-log), and Will be handled and stored in conformance to QA Class e.
I at the Rancho Seco site.
5.
The qu'ality classification of each' major component will be identified on the Master Equipment List maintained by Nuclear Operations.
Nuclear Engineering is responsible for determining the a.
quality classification of all major components based upon the General Requirements of this Quality Assur-ance Procedure.
The classification does not require that every part comprising a portion of the major component be classified at that level.
As allowed by the Code, the classification rules permit evaluations to be made regarding component failure, pressure 3-3 L

..l-QUALITY ASSURANCE PROCEDURE N0. 3 boundary limitations and simil.sr types of criteria for electrical' components to determine their safety
. significance in determining their classification.
b.
Nuclear Engineering uses various informational aids to determine the proper classification of individual components and circuits.
The-classification of an individual part within a major' component requires judgment on the part of the Nuclear Engineering and Quality Assurance Departments to defi~ne the critical nature of the component viithin a particular system.
