Inspection Summary:
Inspection on January 18-19, 1982 (Reports No. 50-295/82-02; 50-304/82-02)
Areas Inspected: Nonroutine, unannounced inspection of radioactive material
transportation activities and inplant radiation safety aspects of the Unit
1 primary to secondary steam generator leakage. The inspection involved
15 inspector-hours onsite by one NRC inspector.
Results: Of the two areas inspected, one apparent item of noncompliance
was identified in one area (failure to verify if a transferee was author-
ized to receive byproduct material before transfer - Section 4).

General
This inspection, which began at 9:30 a.m. on January 18, 1952, was
conducted to examine the licensee's program for transportation of
radioactive material. Also, the inplant radiation safety aspects
of the Unit 1 primary to secondary steam generator leakage were
reviewed.
3.
Transportation Activities
The licensee's program for transportation of radioactive material was
reviewed.
Responsibility for transportation activities is shared by
the Rad / Chem Group, Radwaste Operating Group, and QA/QC. Surveys,
labeling, marking, package selection, activity calculations, and
shipping papers are the responsibility of the Rad / Chem Group.
Pack-
aging, loading, transport scheduling, and notifications are the
responsibility of the Radwaste Operating Group. The Quality Control
Group is responsible for verifying that certain procedural steps are
completed and for performing cask / vehicle inspections. The Quality
Assurance Group observes selected procedural steps, such as radiation
surveys, to ensure compliance with DOT /NRC regulations.
Written procedures are used which specify all necessary documenta-
tion, notification, survey, and package preparation requirements
for each type of shipment. The following procedures were reviewed
to determine if they are consistent with 10 CFR 71 and 49 CFR 170-189.
No problems were noted.

Preparation and Shipment of Radioactive
Material
The licensee made 214 radioactive materials shipments in CY 1981.
Of these, 165 were radioactive waste shipments to burial sites and
49 were miscellaneous radioactive material shipments such as con-
taminated contractor equipment to other reactor sites and liquid
samples for analysis at contractor labs. The inspector reviewcd
records of each shipment made in CY 1981 for compliance with NRC
and DOT transportation regulations. No problems were noted.
No items of noncompliance were identified.
4.
Transfer of Byproduct Material
During review of radioactive material shipment records, the inspector
compared quantities shipped against possession limits listed in the
consignees' license.
It was noted that shipments were made on
April 15, 1981 and August 21, 1981, to National Nuclear Corporation-
(NNC), California License No. 1718-43. The Apri ? shipment consisted
of two boxes .containing contaminated fuel rack testing equipment with
a total activity of 0.2 microcuries of Co-60.
The August shipment
consisted of one box containing detector cables contaminated with
500 microcuries of mixed fission products, a Cf-252 source, and two
boxes of clean equipment. A check of the portion of NNC's. license,
in the licensee's files, indicated that NNC was not authorized to
possess the contaminated equipment contained in these two shipments.
On January 19, 1982, the licensee _ contacted NNC and learned that they
were licensed to possess up to 1.0 microcurie of byproduct material.
NNC agreed to send a copy of this part of their license to Zion.
Based on this information, it appears that the April 15, 1981 shipment
did not constitute an unauthorized transfer.
On January 20, 1981, NNC contacted the licensee and informed them that
the August 21, 1981 shipment was sent to Prairie Island Nuclear _ Plant
instead of NNC. Apparently, an NNC_ employee directed the carrier _to'
deliver the material to Prairie Island, a destination not 31sted on.
the shipping papers. -Based on this information, it appears _that the
August 21, 1981 shipment did not constitute an unauthorized transfer.
Although it appears an unauthorized transfer did not occur, the
licensee failed to verify whether NNC was authorized to receive the

contaminated equipment before transfer as required by 10 CFR 30.41(c).
This is considered an item of noncompliance.

Turbine Building Radiological Controls
Steam generator tube leakage, over the last several months, has caused
low level contamination to build up in certain secondary systems
located within the turbine building. The licensee has identified
several components where low level contamination has concentrated.
These areas have been barricaded and posted as contaminated areas.
The inspector conducted an independent radiation and contamination
survey of selected areas within the turbine building.
Low level
contamination was found in one area that was not previously roped off.
The licensee corrected this problem.
The inspector reviewed the latest survey of the turbine building which
was conducted December 18, 1981. Contaminated areas were identified
on the survey maps, but the levels of contamination were not indicated.
The licensee stated that the frequency of turbine building surveys
had not been increased because of manpower shortages. The inspector
stated that as long as steam generator leakage continues at the
present rate, the turbine building survey frequency should be in-
creased. Also, it was noted that airborne tritium samples had not
been taken in the vicinity of steam leaks such as the one the in-
spector found near the turbine building fire sump. The only airborne
tritium sample collected is the weekly routine sample on the turbine
floor which is used for release quantification.
Samples in the
vicinity of steam leaks should be collected for worker occupancy
assessments. These matters were discussed during the exit meeting
and will be reviewed during a future inspection.
(295/81-02-02;
304/81-02-02)
A cursory review of turbine building relcase pathways and effluent
cwitrols was conducted.
No problems were noted.
6.
Exit Meeting
The inspector met with licensee representatives (denoted in Section 1)
at the conclusion of the inspection on January 19. 1982. The inspector
summarized the scope and findings of the inspection.
In response to
certain matters discussed by the inspector, the licensee:
Stated they would review the need for increasing the frequency
a.
of turbine building surveys.
(Section 5)
b.
Stated they would review the need for conducting additional
airborne tritium sampling in the vicinity of steam leaks within
the turbine building.
(Section 5)
c.
Acknowledged the item of noncompliance.
(Section 4)
