Re:
NRC Audlt 78-15
Dear Mr. Engelken:
The Audi t 78-15 conducted by inspector Thomas stated that it appeared
'that two of our activities were not conducted in full compliance with Nuclear Regulatory Commission requirements.
The Appendix A of your letter stated:
A.
Contrary to 10 CFR 20.203(f), at the time of..the Inspection a Vent Rig Filter container located in the machine shop in the Auxillary Building was not ' labeled to indicate the presence of i.
radioactive materials in excess of the quantitles listed in Appendix C of 10 CFR 20.
The quantity of radioactive material ir, the container was sufficient-to cause rediation levels of 5 mr per hour at a distance of ten feet from the container.
This is a deficiency.
B.
Contrary to 10 CFR 20,203(b), at the time of the inspection a radiation area associated with a Vent Rig Filter container located in the machine shop in the Auxiliary Building was not posted.
A radlation survey conducted by the inspector during the walkthrough inspection identifled radiation levels of 5 mr per hour at ten feet f rom the container.
This is an infraction.
The District has reviewed your observations and agrees that certain practices should be corrected and has taken the following corrective actions:
Violation of 10 CFR 20.203(f), improper labeling of a container which'
~
held radioactive material'in excess of quantitles of radioactive material listed -
-in Appendix C of 10 CFR 20, was the result of inadequate attention to the proper
' labeling of radioactive material'as called for.by the Rancho Seco Radiation
' Control. Manual, specifically Section 3.1.2.1.6.

had been used as a containment for radioactive " crud" in a valve backwash operation and had been stored in a "High Radiation" area without proper labels attached.
It subsequently removed from the "High Radiation" area in preparation for another
~was
-valve cleaning operatlon.
In its second location the filter radiations emitted were sufficient to constitute a new "High Radiation" area within the accessible 7
zone, thus resulting in an infraction of 10 CFR 20.203(b) which requires posting
)
of radiation areas.
Conta!ners of this kind, which already have the radiation symbol prominently embossed, will also have a firmly affixed sign with the words " Caution - Radioactive Material", upon which the radioactive contents are identified.
In addition, the room or area in which such containers are stored will have a sign appropriate to the radiation level in the room or area.
The citations and remedial actions proposed have already been the subject of discussion in a training program involving all Health Physics cc.ntrol personnel.
