~

SNUPPS-C Item 260.71C Section 17.1.2.2 of the standard format (Regulatory Guide 1.70) requires the identification of. safety-related structures, systems, and components controlled by the QA program.

You are requested to supplement and c.1arify Table 3.2-1 of the Callaway FSAR in accordance with the following:

The following items do not appear on FSAR Table 3.2-1.-

Add a.

the appropriate items to the table and provide a commitment that the remaining items.are subject to the pertinent requirments of the FSAR operational quality assurance program or justify not doing so.

a.5 Refueling machine Callaway Position:

Already in Table 3.2.1, Section 3.0, revision 7.

Table 3.2.1 will be revised to show QA program Y-W2.

See attachment 1.

a.6 Spent fuel handling tool Callaway Pocition:

Already in Table 3.2-1, Section 3.0, revision 7.

Table 3.2-1 will be further revised to show QA program Y-W2.

See attachment 1.

a.7 Radiation shielding doors t

Callaway Position:

Already in Table 3.2-1, Section 8.2 (Our position is that this item is not safety related).

Adequacy of this shielding is verified by periodic radiation surveys.

a.8 Radic' ion monitoring (fixed and portable)

Callaway Position:

It is Union Electric's position that items 8-16 of 260.71c(a) should not be included in Table 3.2-1, or be subject to the requirements of the operational quality assurance program.

Union Electric does feel that NUREG 0761,

" Radiation Protection Plans for Nuclear 1

Power Reactor Licensees" Draft Report, March 1981, which is presently in draft form and out for comments, provides the c

necessary guidance in formulating the Callaway Radiatlon Protection Plan.

The Callaway Radiatica Protection Manual (CRPM) and Radiation Protection (RP) procedures together will constitute the Callaway Radiation Protection Plan.

(CRPP). outlines the proposed CRPM.

The outline lists the 260.71C-2 i

f SNUPPS-C major areas to be addressed in the manual.

It is intended that the CRPM will be a concise statement of the Callaway Radiation Protection Plan that can be understood by all plant personnel.

The manual will be written in general and brief terms with the specifics of the plan to be addressed in the implementing RP procedures.

The Callaway Radiation Protection Plan will be developed in accordance with applicable regulatory requirements, regulatory guides, industry standards, and accepted industry practices, and will incorporate sufficient managerial and administrative controls to ensure that a 4

high level of radiation protection is provided. outlines the implementing procedures.

These procedures have been broken down into areas as recommended by the NUREG.

Ic is intended that administrative controls will be implemented via incorporation into administrative and programmatic level procedures which will receive Onsite Review Committee (Plant Review To verify Group) review and approval that radiation protection functions are being performed as required and that a high level of radiological safety is maintained, periodic review and audit of the radiation protection program will be performed by an independent audit group of Union Electric Nuclear Engineering (i.e., the corporate health physics group or their consultant).

Periodic is to be interpreted as annual; however, when warranted by identified program deficiencies a more frequent review-schedule of the deficient area may be implemented.

The specified audi t frequency is based on established l

industry auditing practice and the assumption that a corporate audit at an annual frequency in combination with regulatory, ANI and INPO inspections will l

provide adequate review and evaluation of program performance.

The General Office Quality Assurance Group will review the i

activities and Audit program of the independent audit group to assure that i

appropriate audit procedures are r

SNUPPS-C established and implemented.

The performance of audit and review of the areas identified in items 8-16 to assure program effectiveness is_ consistent with the position of NUREG 0761.

The audit program will be conducted in accordance with established auditing principles:

1.

use of inspectors / auditors with training and expertise in the area being audited 2.

use of audit personnel with no responsibilities or " vested interests" in the areas being reviewed 3.

documentation and review by management of audit results and findings 4.

performance of corrective or followup actions as appropriate Additional quality assurance for items 8-16 of 260.71c(a) are built into RP procedures utilizing quality assurance provisions from regulatory guides.

An example is the respiratory protection program.

Quality assurance for procurement of respiratory equipment is maintained by the purchasing of only NIOSH certified equipment.

In complying with Reg. Guide 8.15, additional quality assurance is established in the respiratory protection program.

In summary, the program described above will meet or exceed the equivalent applicable portions of the Union Electric sperational quality assurance program.

a.20 Roof drains and parapets of buildings which house safety related equipment.

Callaway Position: Not safety related--no credit is taken for these in FSAR safety analyses, but.they are considered in the overall load design of the building.

plant are important to safety because they:

a.

Assure the integrity of the reactor coolant pres-sure boundary.

b.

Assure the capability to shut down the reactor and maintain it in a safe condition.

L c.

Assure the capability to prevent or mitigate the consequences of accidents which could result in potentiel offsite exposures comparable to the

. guideline exposures of 10 CFR 100.

d.

Contain or may contain radioactive material.

The purpose of this sect! n is to classify structures, i

systems, and components according to the importance of the item in order to provide reasonable assurance that the facility can be operated without undue risk to the health and safety of the public.

Table 3.2-1 delineates each of l

the items in the plant which fal1 Sunder the above-mentioned categories and the respective associated classification that the NRC, ANS, and industrial codes committees have devel-i oped.

Each of the classification categories in Table 3.2-1 is addressed in the following sections.

For identification of system and subsystem boundaries, Table 3.2-1 is supplemented (i.e., referenced to applicable figures) by piping and instrument diagrams which have been marked to i
