400 Chestnut Street Tower II June 17, 1980 Director of Nuclear Reactor Regulation Attention:
Mr. A. Schwencer, Chief Light Water Reactors Branch No. 2 Division of Licensing U.S. Nuclear Regulatory Commission Washington, DC 20555
Dear Mr. Schwencer:
In~the Matter of the Application of
)
Docket Nos. 50-327 Tennessee Valley Authority
)
50-328 Enclosed for your review are 20 copies of a revised response to question 12.16 for the Sequoyah Nuclear Plant (SNP). The original response has been revised to include a description of the administrative pracedures in effect at SNP that control access to areas adjacent to the fuel transfer tube. These areas can experience high radiation lesals during fuel handling operations. The revised response will be incorporated into the SNP Final ~ Safety Analysis Report with the next amendment.
Very truly yours, TENNESSEE VALLEY AUTHORITY

-12.16.
j.
. Describe precautions taken to prevent inadvertent employee
' access during fuel transfer to the very high radiation areas l
in1the vicinity of the fuel transfer tube.
If there is suf-ficient permanent. shielding to ensure acceptable radiation l.
levels in adjacent potentially occupied areas.. provide relevant plan and elevation drawings.
l
' Response i
' Accessible areas near the fuel transfer tube are protected with permanent shielding to limit dose rete to 5 mrem /hr or.less during fuel transfer.
l' In the emergency passagewa,e under the fuel transfer tube the permanent
[
shielding may allow dose rates as high as 210 mren/hr during fuel transfer.
l
-Plant parsonnel are prohibited from entering the areas adjacent to the fuel transfer tube during normal fuel handling operations by an administrative j
l procedure. This is specified in a precaution in the Sequoya) Nuclear i
Plant: Fuel Handling' Instructions.
This area is shown on figure 12.19 and the shielding is described in l
section 12.1.2.-
The fuel transfer tube shielding at Sequoyah is similar to that.at Watts Ear Nuclear Plant. -(See Watts Bar FSAR Figure 12.3-12.)
