General
This inspection, which began at 12:15 p.m. on December 18, 1979, was
conducted to examine the licensee's processing, packaging, transfer,
and transport of low-level radioactive waste materials in response
3.
Regulations and License
The inspector verified that the licensee possessed current require-
ments of the commercial burial sites and a current copy of Nuclear
,
Regulatory Commission regulations for the transfer, packaging, and
transport of radioactive material. Methods for maintaining these
i
documents current had been established by the licensee.
The licensee had not procured an updated copy of the Department of
Transportation (DOT) regulations at the time of this inspection.
Difficulties apparently had been ancountered with availability
of the documents from two government offices. The licensee has
since reported that an updated copy of the DOT regulations has
been received. This will be verified during a future inspection.
4.
Designation of Responsibilities
Toledo Edison Nuclear Quality Assurance Procedure QAP 5220 and
Davis Besse Administrative Procedure AD 1850.00 delineate re-
spensibilities for - 7 cessing, packaging, transfer, and transport
of radioactive mat-.lal.
Although the designations of these
responsibilities are relatively clear, some problems were evident
-in implementing these responsibilities, especially between Station
Services personnel and Chemistry and Health Physics personnel. This
matter was discussed at the exit interview.

Procedures and Checklists

The inspector selectively reviewed the following procedures related
to the transfer, packaging, and transport of radioactive waste ma-
terial.

Solid Radioactive Waste Disposal
No discrepancies from the procedure review and approval require-
ments specified in Section 6 of the Technical Specifications were
noted.
The following problems were noted regarding procedure coverage and
implementation.
(1) A procedure had not been written for shipment
of low-level radioactive waste in wooden boxes.
(2) Packaged Rad-
waste Information forms and Solid Waste Storage Inventory and Dis-
posal logs were not used consistently.
(3) Written instructions
were not available for packaging of filters.
(4) Informal hand-
written procedures were used in place of formally approved proce-
dures which were readily available. These matters were discussed
at the exit interview.
Item 2 above is considered an unresolved
item which will be reviewed further during a future inspection.
6.
Training
The inspector reviewed the training program for personnel involved
in the processing, packaging, transfer, and transport of radioactive
material.
A revised training program for personnel involved in the processing
of low-level radioactive waste (i.e., operators and station services
personnel) was expected to be implemented by the end of January, 1980.
This training effort, which is under the purview of the Training
Department, will include use of formal qualification records to
document equipment knowledge and proficiency levels.
Instruction in regulatory and procedural requirements applicable to
the transfer, packaging, and transport of radioactive materials is
conducted by the Chemistry and Health Physics Section. This training,
last conducted in the latter part of 1978, was expected to be updated
and conducted again by the end of March 1980.
These items will be reviewed further during a future inspection.

Audits
The inspector reviewed the licensee's audit activities regarding
low-level radioactive waste transfer, packaging, and transport
activities. Conduct of the radwaste management audit is speci-
fied in QAP 5220. Although no audit frequency is specified in
_
QAP 5220, an annual frequency was recently added to the audit
schedule. The two most recent audits of radwaste activities were
conducted in June'1978 and October 1979. One item remains out-
standing from the June 1978 audit. This item, related to main-
tenance of training and qualification records, was scheduled for
completion by January 31, 1980. According to licensee QA per-
sonnel, low-level radioactive waste transfer, packaging, and
transport activities will be included in future radwaste manage-
ment audits.
The October 1979 audit was conducted in response to IE Bulletin 79-19.
The audit included an examination of Items 1-6 of IE Bulletin 79-19,
except that in the area of procedures (Item 4) the audit examined
the administrative review and approval methods for new and revised
procedures but did not review procedure coverage or implementation.
This item was discussed at the exit interview. The licensee agreed
to perform additional audit activities in this area. This item will
be reviewed further during a future inspection.
,
Administration of the audits was satisfactory regarding audit plans,
reports, corrective actions, and qualifications of personnel.
8.
Waste Packaging Systems
The licensee's installed radwaste solidification system (UF) has
never been used for radwaste processing, due to operational prob-
lems. A contractor provides onsite solidification services (UF).
The radwaste is solidified in 300 cubic foot liners, (coated for
corrosion resistance), which are also used as temporary storage
tanks. The liners and solidification equipment'are located in
the refueling building track alley. Normally, approximately two
to three liners are processed per month. Due to burial site re-
strictions on receipt of free liquid, little radwaste was solidi-
fied during the last half of 1979. The licensee had resumed
solidification operations shortly before this inspection upon
clarification of the Barnwell, South Carolina burial site re-
_quirements allowing free liquid in quantities totaling less than
one percent by volume. Multiple liner drainings were being con-
ducted to verify compliance with this requirement.
In addition'to the solidified evaporatoe bottoms, dry wastes (DAW),
both compactible and noncompactible, and filters have been shipped
offsite as radioactive waste.
It has not been necessary to ship
-radioactive resins from the site yet. Two problems were noted
regarding radioactive waste shipments:
(1; although DAW has been
packaged in wooden boxes (4 ft. x 4 ft. x 7 ft.) in addition to

o 9 e
55-gallon drums, the licensee had no procedure defining design
specifications and usage restrictions for the wooden boxes; (2)
Seal injection filters had been shipped in lead-lined 55-gallon
drums as LSA material although evaluations were not available'to
verify that the radioactive material was properly classified as
LSA. This latter item is considered unresolved pending completion
_
and review of evaluations to determine the proper shipping classi-
fication of these filters.
All radioactive waste shipments to date have been classified as LSA
or greater than Type A quantities. These shipments were made in ap-
propriate packages for their classifications. Shipment records
required by 10 CFR 71.62 are maintained.
9.
Examination of Package
The inspector examined two 300 cubic foot liners containing UF solidi-
fled evaporator concentrates. The waste matrix was solid (no free
liquid) when tested at the top of each liner by the inspector. The
liners were not equipped with drain plugs; a vacuum draining system
was installed. The vacuum drain was o.perated in the presence of the
inspector; no significant free liquid was extracted from the solidi-
fied liner checked.
A 55-gallon drum (B228-79) containing compacted trash awaiting ship-
ment was selected by the inspector and examined for proper contents.
The drum top was removed and the drum tipped to cLeck for the presence
of free liquid. No liquid was observed; the drum (ontents were as
described in the licensee's records.
10. Unresolved Items
Unresolved items are matters about which more information is required
in order to ascertain whether they are acceptable items, items of
noncompliance, or deviations. Unresolved items disclosed during the
inspection are discussed in Paragraphs 5 and 8.
11.
