EXECUTIVE SUMMARY
Zion Generating Station, Units 1 & 2
NRC Inspection Reports 50-295/96021, 50-304/96021
e An apparent violation was identified concerning the shipment of radioactive
materials. The external surface of a December 9,1996 limited quantity shipment
from Zion exceeded the radiation dose rate limit of 49 CFR 173.425. Problems
were also identified concerning the coordination and planning of radioactive material
shipping operations. (Section R1.1)
e Access to safety related equipment continued to be radiologically encumbered.
Pump sealleakage contributed to the high number of contaminated areas within the
auxiliary building. Several examples of inadequate radiological housekeeping and
control of radiological boundaries were identified. (Section R1.2)
e Although the licensee had focussed efforts on resolving operability issues for the
4
steam generator blowdown and radioactive waste (radwaste) systems, material
condition deficiencies, including inoperable chemical drain tank pumps, were not
resolved. Radwaste operators continued to work around inoperable equipment.
Inconsistencies were identified concerning radwaste system configurations and the
Updated Final Safety Analysis Report (UFSAR). (Section R2.1)
e Two apparent violations were identified concerning radioactive material shipping
procedures. The licensee had not adequately maintained certain procedures to be
consistent with the revisions to regulatory requirements. In addition, the licensee
had not properly implemented procedures concerning the use of radionuclide scaling
factors in determining the activity of radioactive waste. (Section R3.1)
e An apparent violation was identified for not adequately implementing radiation
control procedures. Operations personnel removed instruments from a posted
contamination area without containing the instrument or having the instrument
released by radiation protection personnel. (Section R4.1)
e The licensee demonstrated good communication and coordination during the
December 4,1996 medical drill. The licensee was effective in minimizing the
spread of simulated radioactive contamination, with some exceptions.
(Section R4.2)
e Radioactive material shipping training lesson plans were consistent with the
revisions to 10 CFR Part 71 and 49 CFR Parts 172 and 173. An apparent violation
was identified concerning the failure to train two operations personnel in
accordance with procedures. (Section R5.1)
e The licensee's self assessments of the radioactive material transportation program
were not thorough and failed to identify fundamental radioactive material shipping
problems. (Section 7.1)

IV. Plant Support
R1 Radiological Protection and Chemistry (RP&C) Controls
R 1.1 Transoortation of Radioactive Materials
a. Insoection Scone (83750,2515/1331
The inspector reviewed the shipping documents for the following radioactive waste
(radwaste) and material shipments and verified the licensee's waste classification,
and package classification, labeling, and shipping papers:
ZRW 96-02 Dewatered ion Exchange Resin (1/25/96);
ZRW 96-12 Dewatered lon Exchange Resin (4/24/96); I
,
ZRW 96-25 Dewatered lon Exchange Resin (10/24/96); and
ZRM 96-131 Radioactive Material (12/9/96).
The inspector also observed the licensee's preparation and packaging of a liner of
ion exchange resin (ZRW 97-01) for shipment to a radwaste burial site.
b. Observations and Findinas
During the review of the shipping documents, the inspector identified problems
concerning the licensee's implementation of shipping and waste classification
procedures (also see Section R4.1). With the exception of radioactive material
shipment ZRM 96-131, the inspector verified that the licensee's waste ,
classification and shipping classifications were accurately calculated and that l
packaging requirements were met. The inspector also observed that the shipping
papers were completed as required.
The inspector reviewed documentation about a problem concerning the licensee's
December 9,1996 shipment of radioactive material (ZRM 96-131) to the Byron
Nuclear Station. Although the material was shipped as a limited quantity shipment,
the Byron staff identified that the package's contact dose rates of 0.7 mrem /hr
exceeded the Department of Transportation's (DOT) contact radiation limit of
0.5 mrem /hr for that type of package. Zion Station's documented survey of the
shipment clearly indicated the actual contact dose rate of 0.7 mrem /hr, but
personnel incorrectly documented that dose rates were less than 0.2 mrem /hr on
the shipping forms. Although four members of the licensee's staff reviewed this
information, the problem was not identified until the Byron staff performed an
incoming shipment review. Byron personnel made a courtesy notification to NRC to
report the problem with the shipment.
10 CFR 71.5 requires, in part, that each licensee who transports licensed material
outside of the site of usage, or where transport is on public highway, or who
delivers licensed material to a carrier for transport, shall comply with the applicable
Department of Transportation regulations in 49 CFR parts 170 through 189
appropriate to the mode of transport. 49 CFR 173.421 requires, in part, that a
3
I
l
.
Class 7 (radioactive) material whose activity per package does not exceed the limits I
specified in 49 CFR 173.425 and its packaging are excepted from the specification
l
packaging, marking, and labelling, and the shipping paper and certification l
requirements, if the radiation level at any point on the external surface of the '
package does not exceed 0.005 millisievert (mSv)/hr (0.5 mrem /hr). The failure of
the licensee to properly ship radioactive materialin accordance with 49 CFR
173.425 is an apparent violation (eel No. 50-295/96021-01(DRS) and )
50-304/96021-01(DRS)). I
On January 8,1997, the inspector also observed the packaging of a high integrity
container of ion exchange resins (ZRW 97-01) and identified the following
problems:
, e Poor planning and coordination between the radiation protection (RP) and l
operations staff was noted. The operations staff had unloaded an empty I
liner from a carrier's vehicle, had weighed the full liner, and were preparing
to move a full liner of ion exchange resins onto the carrier's vehicle.
However, minutes before the liner was to be loaded on the carrier's truck, i
RP personnel notified the operations staff that they did not have a curreret l
analysis for the resin. All activities in support of loading of the liner we.e
suspended.
- While positioning the carrier's truck into the Radwaste Annex, the licensee
directed the carrier's truck near a contaminated area boundary. The truck
struck and moved the boundary. The truck also brushed against a storage
cask (containing a loaded liner) within the contaminated area in the
Radwaste Annex.
Although a violation of NRC requirements was not identified, this evolution
could have potentially damaged the storage cask containing the resins and
could have potentially contaminated areas outside of the posted area.
As immediate corrective actions for the problems described above, the licensee
suspended all radioactive material shipping on January 10,1997, and bcgan to
review, delete, and/or revise a number of shipping procedures to be consistent with
the requirements.
c. Conclusions
An apparent violation was identified concerning the shipment of radioactive
materials. On December 9,1996, the licensee shipped radioactive material as a
limited quantity shipment which exceeded the limits of 49 CFR 173.425. Problems
were also identified concerning the coordination and planning of radioactive material
shipping operations.

R1.2 Plant Radioloaical Conditions
a. Insoection Scoce (83750,86750)
The inspector reviewed the radiological conditions of the plant and assessed the
effect of radiological contamination and high radiation levels on access to safety
related and radwaste equipment. Specifically, the inspector reviewed the licensee's
surveys of the auxiliary building (ABi and the associated posting and control of
radiological hazards. In addition, the inspector assessed the radiological
housekeeping in the AB and the control of contaminated area boundaries.
b. Observations and Findinct
The licensee continued to have several radiological impediments encumbering
access to safety related equipment, as documented in NRC Inspection Report 50-
295/96016(DR S), 50-304/96016(DRS). Extensive pump sealleakage contributed
to contamination in several emergency core cooling system (ECCS) pump rooms.
Although these areas were properly posted and controlled, the access to safety
related equipment was significantly impeded in addition, high radiological source
term has resulted in elevated dose rates and numerous hot spots. For example, the
licensee posted and controlled all four of the residual heat removal (RHR) pump
rooms as high radiation areas (HRAs) and contaminated areas (CAs). The RHR heat
exchanger rooms were similarly controlled, with the unit 1 (U1) rooms being locked
HRAs as well. Although a small non-contaminated area walkway was maintained in
the RHR rooms, the access to equipment remained encumbered.
The centrifugal charging pump (CCP) rooms were accessible; however, the overall,
higher U1 dose rates resulted in the licensee posting and controlling the 1B CCP as
an HRA. The inspector also observed that the pumps and pedestals were posted as
CAs, owing to pump sealleaks and visible boric acid crystallization.
Similar to the ECCS pump rooms, the inspector observed that the access to areas
containing radwaste system components was highly, radiologically encumbered.
As a result of numerous hot spots and high radiological source tcrm withir: the
radwaste tanks, the licensee controlled the AB equipment drain tank (EDT) and
chemical drain tank (CDT) as locked HRAs. In general, the inspector noted that
pump sealleakage had also resulted in the posting of radwaste tank pumps as
contaminated areas, in addition, the inspector observed that the licensee had also
restricted access to the crystallizer and evaporator rooms, v5hich had been
'
abandoned in place, with RA and CA postings at the access point and with
radiation protection (RP) permission necessary for access.
During plant observations on December 3 and 4,1996, the inspector identified
problems concerning radiological boundary control and housekeeping in several
areas of the AB. For example, the inspector observed several signs of leakage
within the U1 and U2 hnrizontal pipe chases, including leakage from the high
radiation sampling system waste tank pump. The inspector also identified
protective clothing strewn about the area and fulllaundry collection containers
improperly stored within CAs. The inspector also identified several radiological
housekeeping issues in a work area outside of the U2 volume control tank room
5

.
including hoses not properly secured crossing CA boundaries, hoses containing
fluids not leading to collection devices, and protective clothing strewn about within
the CA.
c. Conclusions
.
Access to safety related equipment continued to be radiologically encumbered.
Pump sealleakage contributed to the number of contaminated areas within the AB.
Several examples of inadequate radiological housekeeping and control of
radiological boundaries were identified.
R2 Status of RP&C Facilities and Equipment l
I
R 2.1 Material Condition of Radioactive Waste Processina System I
a. Scone (86750)
The inspector reviewed the material condition of the radwaste processing system.
The inspector compared the current system condition and operation to the
licensee's Updated Final Safety Analysis Report (UFSAR) section 11.2, " Liquid
Waste Management Systems," and section 11.4, " Solid Waste Management
System." The inspector also reviewed the outstanding work orders for the system )
and the licensee's progress in performing system maintenance. The inspector also l
discussed system operability and planned corrective maintenance with members of
the operations staff.
b. Observations and Findinas ,
i
With the exception of the spent resin storage tank (SRST), the inspector verified
that the integrity of the radwaste tanks was acceptable and did not identify any
indications of leakage. However, as described in Section R1.2, high dose rates
impeded access to several radwaste tank rooms. Current radiological conditions
(i.e., estimated general area dose rates in excess of 40 rem /hr) made the SRST
inaccessible. However, the licensee had decontarninated the tank in July 1996 to
perform maintenance on valves. RP personnel, who were involved in the evolution,
indicated to the inspector that the integrity of the tank was good and that there
were no visible indications of resin leakage from the tank.
The inspector observed that both CDT pumps were inoperable. The A pump was
completely removed from tae pump pedestal and the B pump was wrapped with
plastic to contain leakage. Operations personnel indicated that the pumps had been
out of service for over ten years and that the pump suction valves had been
isolated, in accordance with 801-67D, " Liquid Waste Disposal Chemical Drain
Tank," Revision 3, operations personnel directed the unanalyzed CDT contents to
the OB AB sump, which was normally pumped to the AB floor drain analysis tank.
The licensee identified this practice as an operator work around. Although the
problem was not documented in a work request and progress in correcting the
problem was slow, the system en0ineer had an action plan to correct the
deficiencies. The inspector noted that the licensee's process was in conflict with
the UFSAR. As described in UFSAR Section 11.2.2.8, the contents of the CDT
6
_ _ - - .
were to be mixed and sampled, then pumped directly to the applicable radwaste
processing system. In addition, the inspector noted that the AB floor drain analysis
tank and AB sumps (UFSAR Section 11.2.2.2 and 11.2.2.8.2.7, respectively) were
not designed to accept inputs from the CDT nor inputs to the CDT. At the time of
this inspection, the licensee was determining if a safety evaluation had been
completed for the above system configuration. (Unresolved Item No. 50-295/
96021-02(DRS) and 50-304/96021-02(DRS))
In addition to the discrepancy above, the inspector also noted other issues
concerning radwaste operations which were not in conformance with the UFSAR.
The inspector also noted that UFSAR Section 11.2.2.8.5 states that a radwaste l
evaporator was to be used for radwaste processing. However, the licensee did not
have any plans or work requests to repair the non-functioning radwaste evaporator.
The licensee exclusively uses ion exchange demineralization to process the contents
of the liquid radwaste tanks. UFSAR section 11.2.2 also states that the contents
of radwaste tanks were to be mixed and sampled to determine the most effective
processing of the liquids. Specifically, UFSAR Section 11.2.2.8 indicates that the
contents of the following tanks were to be mixed and sampled prior to being
discharged through a treatment process: AB equipment drain analysis tank, AB
floor drain analysis tank, CDT, and laundry and hot shower drain tanks. However,
chemistry and operations personnelindicated that the licensee did not sample the
contents of each tank prior to processing. After processing the tanks' contents,
the licensee sampled the accumulated, processed liquid waste in the evaporator
monitor tanks. Prior to releasing the processed waste to the lake, the licensee also
sampled the contents of the lake discharge tanks (LDTs). At the time of this
inspection, the licensee was determining if a safety evaluation had been completed
for the above difference in radwaste operations. (Unresolved item No. 50-
295/96021-03(DRS) and 50-304/96021-03(DRS))
The inspector noted some progress in the licensee's actions to resolve
longstanding, extensive material condition deficiencies on the steam generator (SG)
blowdown system. Material condition deficiencies in this system (documented in
NRC Inspection Report 50-295/95016(DRP) and 50-304/95016(DRP)) included
severalindications of valve packing and pump sealleakage. Since September
1996, the licensee dedicated an oversight group to improve system operability and
to complete outstanding work orders. As of November 1,1996, the licensee had
resolved issues on the blowdown system which were of high priority to the
operations staff. After complete resolution of the blowdown system maintenance
problems, the licensee planned to focus efforts on the remainder of radwaste
system issues. A radwaste operations supervisor indicated that over 30 work
requests were in the licensee's system for general radwaste corrective
maintenance.
c. Conclusions
Although the licensee had focussed efforts on resolving operability issues for the
steam generator blowdown and radwaste systems, material condition deficiencies,
including inoperable chemical drain tank pumps, were not resolved. Radwaste
operators continued to work around inoperable equipment. Inconsistencies were
identified concerning radwaste system configurations and the UFSAR.

R3 RP&C Procedures and Documentation
R 3.1 Radioactive Material Shiocina Procedures
a. Scoce (86750 -
The inspector reviewed the licensee's procedures providing instruction in the
classification, packaging, transport, and shipping of radioactive materials and
radwaste. The inspector reviewed the following licensee procedures and their
implementation:
ZAP 620-01, " Radioactive Material Shipping and Receiving Guidelines,"
Revision TA-96-973;
ZRP 5600 3, " Classification of Radioactive Waste for Near-Surface Burial Site
,
Disposal," Revision 0;
ZRP 5600-4, " Completion of Radioactive Material Shipping Record," Revision 2;
ZRP 5600-7, "Off-Site Shipment of Radioactive Material," Revision 0;
ZRP 5600-11, " Radioactive Shipments (RM) (Other Than Waste)," Revision
TA-96-008;
ZRP 5610-2, " Calculation of Curie Content of Radioactive Shipments," Revision 0;
ZRP 5610-4, " Preparation and Shipment of Samples for Special Analysis,"
Revision 0;
ZRP 5610-6, " Surveying Radioactive Material Shipments," Revision 2; and
ZRP 5610-10, " Radioactive Waste Shipments," Revision O.
b. Observations and Findinas
The inspector observed that the licensee had revised procedure ZAP 620-01 to be
consistent with recently implemented revisions to applicable transportation
regulations. ZAP 620-01 contained guidance in preparing packages, consistent-
with the categories of low specific activity (LSA) and surface contaminated object
(SCO). The procedure also contained instructions consistent with the revised
packaging requirements. However, ZAP 620-01 often directed the user to refer to
applicable regulations instead of providing specific instructions. For example, in
determining the type of label for the package, ZAP 620-01 referred the user to 49
CFR 172.403. The licensee indicated that its computer software was used to
ensure that the regulatory requirements were met.
The licensee also used computer software to determine packaging requirements
such as activity limits, LSA classification, and SCO classification for transport of
radioactive materials. The licensee's procedures properly reflected the use of the
computer software which appropriately implemented the applicable regulations. The
licensee also had approved procedures which provided instructions for manual
determination of the above packaging requirements. The inspector determined that
ZRP 5600-7, "Offsite Shipment of Radioactive Material," Revision 0, dated
November 2,1993, contained inaccurate instructions for determining packaging
requirements (i.e., activity limits, LSA classification, SCO classification, etc.).
Specifically, this procedure contained instructions which complied with the previous
regulations and, thus, were outdated. Once this was brought to the licensee's
attentior', the licensee deleted the procedure.
8
.
.
Technical Specification (TS) 6.2.2.A requires, in part, that radiation control
procedures be maintained. The failure to maintain radiation control procedure
ZRP 5600-7 is an apparent violation of TS 6.2.2.A (eel No. 50-295/96021-04(DRS)
and 50-304/96021-04(DRS)).
During a review of shipment documents, the inspector identified that the licensee
had not adequately implemented its radioactive waste shipping procedures
concerning the sampling and analysis of waste streams to determine radionuclide
scaling factors. In accordance with 10 CFR 61.55(a)8, scaling factors are used as
an indirect method to determine radionuclide activity in radioactive waste
shipments. This is done by inferring a concentration of hard to detect radionuclides
by applying scaling factors to a known concentration of an easier to detect
radionuclide provided there is reasonable assurance that the indirect method can be
correlated with actual measurements. Licensee procedures require that sampling
and analysis of certain waste streams be done annually.
The inspector identified that the steam generator blowdown resin scaling factors
had not been analyzed since September 1994. Further, this analysis was not used
because it was determined that the sample was not representative of the actual
radionuclide content of the resin. No additional sampling was performed and there
was no laboratory analysis to support the pre-1994 scaling factors which were in
use at the time of the inspection. The significance of this omission is that the slight
steam generator tube leakage which had occurred since the last valid sample
analysis could have changed the radionuclide content of the blowdown resin.
Additionally, the sampling and analyses of the primary resin waste stream was not
performed from August 1993 through November 1996. Even though the primary
resin was sampled in November 1996, a combined average of 1992 and 1993
sample data was in use at the time of the inspection.
TS 6.2.2.A requires, in part, that radiation control procedures be implemented.
Licensee procedure ZRP 5610-4, dated November 12,1993, requires, in part, that
spent resin samples be sent out for analysis yearly, in accordance with 10 CFR 61
guidelines. ZRP 5610-4 required that annual samples of SG blowdown resin and
primary resin be analyzed in accordance with 10 CFR 61 guidelines and procedure
ZRP 5610-10, dated December 12,1994, required that the current shipment be
compared to " annual waste stream analyses". The failure to obtain and analyze
annual samples of SG blowdown resin and primary resin is an apparent violation of
TS 6.2.2.A (eel No. 50-295/96021-05b(DRS) and 50-304/96021-05(DRS)).
c. Conclusion
Two apparent violations were identified concerning radioactive material shipping
procedures. In the first violation, the licensee did not adequately maintain certain
procedures consistent with the revisions to regulatory requirements. The second
violation concerned the failure to have samples of various waste streams analyzed
to establish acceptable scaling factors within the procedurally-specified timeframe.

R4 Staff Knowledge and Performance in RP&C
l
,. R4.1 - Radiation Worker Practices
L During the inspector's observations of radwaste shipment ZRW 97-01 (Section
i R1.1), the inspector identified an apparent violation of procedure ZAP 610-03,
" Unescorted Access To and Conduct in Radiologically Posted Areas," Revision 1(G),
- dated September 12,1996. This procedure states that personnel are to contain
)
contaminated equipment removed from contaminated areas or have the equipment
released by a radiation protection technician. On January 8,1997, the inspector
j observed an operations individual pick up a rod in a clean area, use the rod .to
j manipulate potentially contaminated equipment in a posted contaminated area, and
1 . remove the rod from the posted contaminated area without containing the rod or
j having the rod released by a radiation protection technician. In utilizing the rod to
manipulate equipment within the posted contaminated area, the individual
potentially contaminated the rod. Following the observation, the inspector alerted a
,
radiation protection technician (RPT) in the area, who took control of the rod and
- performed a contamination survey.
TS 6.2.2.A requires, in part, that radiation control procedures be implemented. The
failure to adhere to ZAP 610-3 is an apparent violation of TS 6.2.2.A (eel No.50-
[ 295/96021-06(DRS) and 50-304/96021-06(DRS)). !

R4.2 Onsite Emeroency Medical Drill
l
. 1
a. Insoection Scone (83750,82301)
l
The inspector observed the licensee's December 4,1996 onsite emergency medical ,
l drill. The drill scenario included a simulated contaminated, injured person (CIP) who j
had fallen in the 1B CCP room. The inspector reviewed the licensee's response to
- the scenario events, including the licensee's first aid response, evaluation and !
'
communication of radiological hazards, and contamination control.
l b. Observations and Findinas
!
} The inspector observed good communications and coordination with offsite
i responders and between onsite personnel. With the exception of a simulation
problem, the onsite personnel responded to the CIP in a timely manner. The initial
responders (security, operations, and RP personnel) ensured that appropriate first
- aid was administered and that information was properly communicated with offsite
fire protection personnel. The RPTs monitored the CIP's vital signs and ensured
L that the individual remained conscious and aware of what was occurring. The
status of the CIP was appropriately relayed to the offsite fire protection personnel
responding to the scenario events.
Contamination control practices were good, with some minor exceptions. The RP
personnel established a boundary around the CIP to control the potential spread of
contamination and limit personnelin the area. The RPTs also prepared a " clean
area runway" to reduce the potential for contaminating offsite emergency
responders and their equipment. Although the RPTs did not perform extensive
10
.
.
contamination surveys of the CIP, the RPTs indicated that their main concern was
to assess the CIP's medical condition and to stabilize his condition. As a result,
they treated the CIP as potentially contaminated, communicated this to all other
medical responders, and performed further surveys when the CIP was in a stable
condition. The RPTs demonstrated good use of contamination control practices
while treating the CIP. The RPTs donned gloves while working on the CIP and
removing his protective clothing, but the inspector observed that the RPTs did not
always change gloves while moving from more to less potentially contaminated
articles of protective clothing. Potentially, this practice could have spread
contamination to the CIP. In addition, the inspector identified that a security
officer, initially responding to the event, potentially contaminated himself when he
approached the CIP and assessed the casualty. Since the security officer did not
identify that he had been near the CIP, RP personnel did not control or survey this
person to ensure that he did not spread contamination at the accident site.
The inspector also identified a problem concerning the control of the medical drill.
As the CIP was removed from the radiologically posted area (RPA), a drill controller
indicated to the RPTs and RP supervisor that the individual was not to be removed
from the stretcher to enter the personnel contamination monitors (PCMs) (the
rout;ne, automated method of personnel survey) but that he was to be surveyed on
the stretcher in his medically dressed position. Although the RPTs and RP
supervisor were hesitant, they performed a manual survey of the CIP and the
stretcher, then accompanied the CIP to the hospital for additional surveys.
Although allowed by licensee procedures, the inspector indicated to the licensee
that this was a nonconservative decision. For an actual medical situation, a partial
survey and RPT accompaniment would have been appropriate. However, since a
medical situation did not exist, not entering a PCM prior to exiting the RPA could
have potentially resulted in the unnecessary spread of contamination. The licensee
representatives indicated that their original intent was to have the CIP survey
through the PCMs and planned to review RPA access and egress requirements for
future drills.
c. Conclusion )
The licensee demonstrated good communication and coordination during the
December 4,1996 medical ornl. The licensee was effective in minimizing the
spread of simulated radioactive contamination, with some exceptions.
R5 Staff Training and Qualification in RP&C

l
'
a. Scoce (86750. Tl 2515/133)
The inspector reviewed the licensee's training program for personnel involved in the
radioactive waste and radioactive material shipping program to ensure personnel
involved in the shipping program were adequately instructed in the revisions to 1
10 CFR Part 71 and 49 CFR Parts 172 and 173. The inspector reviewed the
following procedures and training lesson plans:

Level 11 Radioactive Materials Shipping Training, Quality Control Personnel, l
Revision 2. l
I
The inspector also reviewed the training history of those persons who were
authorized by the licensee's procedures to release radioactive material shipments.
b. Observations and Findinag
The inspector observed that the lesson plans for the licensee's Radioactive Material
Shipping training was consistent with the April 1996 revisions to 10 CFR 71,49
CFR 172, and 49 CFR 173. The lesson plans contained appropriate instructions
concerning the classification of waste for burial and the requirements for packaging
and shipping radioactive materials, including the LSA and SCO classifications.
In reviewing the licensee's training records, the inspector identified that two of the
seven persons authorized to release / approve shipments of licensed materials were
not trained in accordance with ZAP 200-9, which requires biennial radioactive
materials shipment training in accordance with NRC IE Bulletin 79-19. IE 79-19
states that individuals are expected to be trained and retrained in the following:
(1) DOT and NRC regulatory requirements,
(2) Waste burial license requirements, and
(3) Licensee instructions and operating procedures.
The inspector verified that the two members of the operations staff were involved
in the shipping program and were authorized to release radioactive shipments. In
April 1996, the individuals attended the Radioactive Material Shipping training but
did not successfully pass the associated exam and had not successfully completed
this training since April 1992 and April 1994, respectively. In July 1996, those
persons successfully completed the task specific training (Level 11 Radioactive i
Materials Shipping Training, Quality Control Personnel) which was limited to
instruction on vehicle cnd package inspections and limited regulatory requirements
(i.e., radiation levels and placarding). This training did not fully meet the
requirements of ZAP 200-9. Neither training course appeared to review the
licensee's instructions and operating procedures. Although these individuals were
authorized, the licensee indicated that the two operations personnel had not
released any shipments.
TS 6.1.5 requires that retraining and replacement training of station personnel shall
be in accordance with ANSI N18.1, " Selection and Training of Nuclear Power Plant
Personnel," dated March 8,1971. ANSI N18.1, dated March 8,1971, requires
that a continuing program of training be used for training replacement personnel and
for retraining necessary to ensure that personnel remain proficient. ZAP 200-09,
dated September 17,1992, requires, in part, that personnel, other than stationmen,
involved in the transfer, packaging, or transport of radioactive material shall be
trained in accordance with IE Bulletin 79-19, and retrained biennially. IE Bulletin

79-19 states that personnel should be trained in the DOT and NRC regulatory
requirements, the waste burial license requirements, and in the instructions and
operating procedures for the transfer, packaging, and transport of radioactive
waste. The failure to adequately train personnel in accordance with ZAP 2000-9 is
an apparent violation (eel No. 50-295/96021-07(DRS) and 50-304/96021-
i
07(DRS)).
c. Conclusion
Radioactive material shipping training lesson plans were consistent with the
revisions to 10 CFR Part 71 and 49 CFR Parts 172 and 173. An apparent violation
was identified concerning the failure to train two operations personnel in '
accordance with procedures.
R7 Quality Assurance in RP&C Activities
R7.1 Self Assessments of Radioactive Material Shionino Activities
The inspector reviewed quality assurance audit QAA 22-96-04 " Zion Site Quality
Verification Audit of REMP/ODCM/PCP/RW Shipping" conducted on April 15-19,
1996. The site quality verification (SOV) staff reviewed the status of the
radiological environmental monitoring program, the liquid and gaseous' effluents
program, and the radioactive materials transportation program. The audit
concluded that the radioactive shipping program was sound and that radioactive
shipments were being performed by qualified personnel using approved procedures. 1
Given the fundamental problems identified during this NRC inspection, which j
ranged from worker training and procedural adherence to the shipment of material l'
above applical;le limits, the inspector concluded that this audit was not thorough
and failed to identify basic problems which existed at the time of the audit. The
Quality Assurance Manager indicated that considering a major change to radioactive i
'
material transportation regulations had been implemented two weeks prior to the
audit, an in-depth review of this program to ensure proper implementation of the
new requirements should have been conducted.
V.- Manaaement Meetinas

On January 22,1997, the inspectors presented the inspection results to licensee
management. The licensee acknowledged the findings presented.
The inspectors asked the licensee whether any materials examined during the inspection
should be considered proprietary. No proprietary information was identified.
