General
This inspection, which began at 11:30 a.m. on December 1, 1981, was
conducted to examine the licensee's actions in response to Health
Physics Appraisal and previous inspection findings. The inspection
also included a plant tour and visual observations of facilities
and equipment, posting and labeling, and independent radiation
measurements made by tne inspector.
General housekeeping was adequate.
3.
Licenzee Action on Previous Inspection Findings
(Closed) Noncompliance Item (409/80-10-09): Failure to meet Technical Specifications 6.8.1 and 6.11, adherence to radiation protection re-
quirements. Procedures concerning tightening of ring lock nuts on
filled radwaste drums and posting of hot spots have been revised.
(Closed) Noncompliance Item (409/81-19-02): Failure to post a " Caution
Radiation Hot Spot" sign in an area containing a radiation field in
excess of technical specification limits. A locked barrier was in-
stalled, and a new procedure defining the use of hot spot stickers has
been developed.
4.
Monitoring
As noted during previous inspections, certain technical problems
concerning stack sampling need resolution. These items include
replacement of the tygon tubing on the noble gas iodine and
particular monitoring system with hard piping, calibration of the
SPING-4 with noble gas and iodine-131 standards, correction of the
SPING-4 computer memory loss, and revision of SPING-4 procedures
to include calculation of effluent concentrations in case of memory
loss. These matters will be reviewed at a future inspection.
Also, the effect of radiation on the operability of the SPING-4,
during an accident, in its present location was questioned. The
licensee reviewed the possibility of constructing a facility at a
different location to house both the SPING-4 and PING-3 units. On

the basis of this review, they determined the construction of a new
building to be impractical. During this inspection, the licensee
stated they were still reviewing this matter and would, if necessary,
seek other alternatives to minimize the effect of radiation on monitor
operability during an accident.

5.
Health Physirs Training
Since the previous inspection, the licensee has trained Health Physics
Technicians (HPT's) in revised emergency sampling procedures EPP 7
and 8.
Remaining commitments, made in response to the Health Physics
Appraisal (HPA) concerning training, include the rewriting of an
emargency sampling procedure (EPP 6) and the development of a train-
ing manual and implementing procedures.

6.
Internal Exposure Control
.
Since the previous inspection, the licensee is continuing to upgrade
their internal and external exposure program in the following areas:
TLD beta dose equivalent calibrations; TLD gamma dose comparison with
pocket and film dosimeters; phantom construction for whole body
counter calibrations; new germanium detector calibration; and NIOSH
approved full and half mask respirators evaluations. This matter
will be reviewed further during a future inspection.

7.
Instrumentation
Concerning the weaknesses in instrumentation noted during the HPA,
the licensee has revised instrument calibration procedures to include
the recommendations in ANSI N323-1978. Corrective actions still to
be accomplished include providing HP-210 friskers at the exit from the
Waste Treatment Building and calibration of the liquid effluent moni-
tors at m'21tiple poitats using varying concentrations of radionuclides
with similar isotopic compositions.
(0 pen Item 409/81-19-02)
8.
Procedural Adherence
During the HPA, it was noted that there was a need to resolve weak-
nesses concerning procedure coverage and adherence, including incon-
sistencies between Health and Safety Procedures (HSP's) and actual
practices.
The licensee initiated a review of all HSP's in early 1981. Several
have been revised and others will be revised through 1982. Several
of the revised procedures reviewed during this inspection were found
to be significantly improved. This matter will be reviewed during
future inspections.

Plugged Drain Lines (LER 80-12)
In early November 1980, a drain header beneath the turbine building,
going to the 4500 gallon waste water storage tank, was discovered
blocked. The drain header serves equipment and floor drains in a
,
portion cf the turbine building. The blockage apparently was intro-
duced several weeks earlier during injection of grout into voids
beneath the turbine building. Efforts to clean out the drain header
have been unsuccessful. Soil core samples taken beneath the butiding
showed low levels of contamination although. well water samples did
not indicate any radioactivity increases.
In October 1981, the licensee installed a sand point well and hand-
pump to draw water samples at different depths near the west wall
of the turbine building. The licensee located the sampling point
at a position which would provide representative sampling.
Several
attempts to obtain water from the well using 14 feet of tygon tubing
failed. More attempts will be made in the future. This matter was
discussed at the exit interview.

Exit Interview
The inspector met with licensee representatives (denoted in Section
1) at the conclusion of the inspection on December 3, 1981. The
inspector summarized the scope and findings of the inspection.
In
response to certain items discussed by the inspector, the licensee:
a.
Acknowledged the inspector's remarks concerning his review of
Health Physics Appraisal significant findings, and inspection
open items.
(Sections 4, 5, 6, 7 and 8)
b.
Stated that more attempts will be made tu collect water samples
from the well to determine if radioactive material had migrated
from under the turbine building.
(Section 9)
c.
Stated that the positica of the Radiation Protection Engineering
Assistant was expected to be filled in early 1982.
