Dear Mr. Denton:

ULNRC-953 DOCKET NUMBER 50-483 CALLAWAY PLANT, UNIT 1 TECHNICAL. SPECIFICATION AFFIRMATION AND PROPOSED FSAR CHANGES

1) ULNRC-792 dated April 9, 1984

2) ULNRC-816 dated May 11, 1984

3) ULNRC-835 dated May.31, 1984-

4) ULNRC-842 dated Jun'e' 11, 1984 The referenced correspondence affirmed the accuracy of the Callaway Technical Specifications which were issued as Appendix A to the Callaway Facility Operating License NPF-25.

In conjunction with issuance of the

~

Callaway full power license, proposed-revisions to the Technical Specifications were reviewed by members of my staff and discussed with me.

In my judgement the changes do not affect my previous affirmation given in References 1 through 4.

In addition, the attached pages represent differences between the as-built plant and the FSAR. These will be included in the next revision to the FSAR.

Very truly yours, Donald F. Schnell ACP/drs N

The: counting room fan-coil unit and filter unit operate in a

\\j continuous recirculation mode to provide the necessary cooling, filtration, and humidity control of the counting room atmosphere to maintain a saitable ambience for the electronic equipment and personnel in the room.

.The amount of cooling is controlled by a temperature con-troller located in the return air duct to the unit.

The controller functions to maintain the space air temperature at or below 74 F.

A moisture switch, located in the counting room fan-coil unit return air duct, senses the relative humidity of the return air and operates the humidifier, as required, to maintain the space relative humidity between 40 and 60 percent.

A HEPA and prefilter filter unit are provided. upstream of the fan coil unit to minimize the airborne partico'lates in the space.

The control building supply air unit intake, the control building exhaust system, control room pressurization, and the access control exhaust system contain dampers capable of withstanding the effects of extreme wind or tornado con-ditions (3 psi total at a rate of 2 psi /second per Regula-tory Guide 1.76).

These dampers close with a tornado or high fs

(

)

winds and are considered passive since they do not have

'N '

actuation devices.

The dampers located in the exhaust systems are spring loaded to prevent closure during normal system operations.

Based on the outside air design conditions, design space heat loads and operation of the control building HVAC sys-tems, as described above, no area of the control building (except for the laundry and locker areas of the access con-trol area) will exceed a relative humidity of 70 percent.

downstream EMERGENCY OPERATION - Located in the control building supply system ductwork, upstream of the supply unit, are redundant I

radiation monitors

and a smoke detector.

These monitors sense contaminants in the influent and alarm in the control room when limits are exce,eded.

The high radiation and chlorine monitors (chlorine concentra-tions of 5.0 ppm or greater) initiate isolation of the control building normal supply and exhaust systems.

The chlorine monitors comply with the requirements of Regulatory Guide 1.78, as discussed in Table 6.4-1.

Chlorine monitors are not required for the 'Callaway plant per Section 2.2.3.1.3 of the callaway Site Addendum.
