Two unresolved items were identified during this inspection:
1) the licensee will ask their contractor to substantiate the performance of gamma spectral analyses on precipitation semples containing in excess of 10 pCi per liter gross beta activity; 2) the licensee will' attempt to retrieve and perform radium analyses on well water samples containing
.
in excess of 3 pCi per liter gross alpha activity.

General This inspection consisted of an examination of the licensee's preoperational radiological and non-radiological environmental monitoring programs including sampling techniques and procedures, sample collection equipment and locations, and program results.
-
Management control aspects including organizational structure, responsibilities and authorities, and administrative control were also examined. The licensee's,FSAR and Construction Permit were used as the primary inspection criteria. The inspection did not include an examination of the licensee's contract laboratory personnel, equipment or procedures.
- . -
The licensee utilized Industrial Bio-Test Laboratories, Northbrook, N
Illinois to provide laboratory services for analysis of the radio-logical environs monitoring samples collected surrounding the Davis
'
Besse site.
Sample collections are performed by station personnel
.(except for three outlying sites which are serviced by personnel contracted to Industrial Bio-Test Laboratories).
In addition'to the Davis Besse station and Toledo Edison corporate staffs, the following groups are utilized to provide input to the non-radio-logical environmental monitoring programs:
Center for Lake Erie Area Research, Ohio State University, Columbus, Ohio (aquatic monitoring) and the Environmental Studies Center, Bowling Green State University, Bowling Green, Ohio (terrestial monitoring).
!.
Procedural Controls
_.
The licensee's administrative and procedural controls for imple-mentation of the environmental monitoring programs to assure compliance with the monitoring requirements were examined.
This examination included a review of' the assignment of responsibilities and authorities for program management and implementation.
The licensee had, in various stages of preparation, formal procedures defining program administration, sample collections, equipment calibrations, and program audits.
The licensee intends to review the contract laboratory's analytical procedures.
These items will be examined further during a subsequent inspection.

Non-Radiological Environmental Monitoring The non-radiological environmental monitoring program commenced in i
1972 includes preoperational aquatic and terrestial monitoring in the.following specific areas:
terrestial flora, terrestial fauna,
,
soil and atmospheric environment, bird mortality, plankton and benthic r
i organisms, fish and their feeding habits, lake hydrology, and water chemistry.
Results of these monitoring programs through June 1974 were selectively reviewed by the inspectors.
The licensee has I
i apparently complied with the conditions for protection of the envi-ronment as contained in the Construction Permit. A final hydrologic
survey of the lake bottom in the vicinity of the intake and dis-charge pipes is expected to be completed this year.
The licensee
.
intends to continue the preoperational aquatic and terrestial
monitoring programs through commencement of plant opercticns and I
subsequently for tuo to five years at which time the programs will be evaluated for their continuing usefulness.
These areas will be
examined further during subsequent inspections.
5.
Radiological Environmental Monitoring A preoperational radiological environmental monitoring program was f uitiated in the vicinity of the site in July 1972 and will be
!
continued through plant operation. Results of the monitoring program through June 1974 were selectively reviewed by the inspectors.
The licensee has apparently complied with the monitoring program as contained in the FSAR except as noted below.
g
a.
The FSAR program requires that groundwater samples be analysed
.
for radium if the groes alpha count is greater than 3 pCi per liter. Although several well water samples collected during 1973 and 1974 yielded gross alpha counts in execcs of 3 pCi per liter,-specific radium analyses were apparently not conducted.
The licensee stated that the contra't laboratory would bc c
,
contacted and requested to perform specific radium analyses as i
specified in the FSAR in the future and that an attempt would l
be made to retrieve past samples and perform the specific
radium analyses. This item will be examined further during a j
subsequent inspection.
!
l b.
The FSAR similarly requires that precipitation samples be
!
gamma scanned if the gross beta count is greate.r than 10 pCi per liter. Numerous precipitation samples collected during
.
I 1973 and 1974 yielded reported gross beta counts in excess of i
10.pCi per liter.
Gamma spectrographic results for these
. samples were not reported in the contract laboratory's reports.
The licensee stated that the gamma analyses had been conducted
-
and that the results of the analyses would be procured from the contract laboratory.
This item will be examined further during a subsequent inspection.

c.
Clam samples apparently could not be located for collection
,-~q (
)
during'1972 or 1973 but were located in 1974 (although the
's.,s(
sampling locations were not as specified in the FSAR).
The licensee intends to revise the FSAR to reflect the -avail-ability of the clams.
The licensee was informed that the requirement for gathering sufficient preoperational data would be examined further during a subsequent inspection.
d.
It was noted that the licensee had not been collecting three species of wildlife semiannually as specified in the FSAR but rather had been collecting two species of indigenous animal life semiannually and one waterfowl sample on an annual basis.
The licensee stated that the monitoring program as specified in the FSAR would be reviewed based upon discussions with AEC Licensing personnel and proposed Regulatory Guide 4.8 and would be revised accordingly.
This item will be examined further during a subsequent inspection.
e.
At the request of the AEC in 1973, the milk monitoring program specified in the.FSAR had been changed to 1) increase the sampling frequency at the nearest dairy farm from monthly to weekly (during the seasons that milking animals are on pasture)
and 2) improve analytical sensitivity for the I-131 analyses to 0.5 pCi per liter at time of sample collection.
The licensee had originally intended to implement these changes
'
e upon commencement of the operational phase of the monitoring (g program. The licensee was requested, and agreed, to commence (
/
I-131 analyses at the improved sensitivity during the pre-operational program in order to develop a basis for comparison of operational monitoring results.
The licensee expected to commence analyses at the increased sensitivity by January 1975.
f.
The installation and operability of selected monitoring stations
>
were examined.
It was noted that the airborne samplers had been calibrated within the preceding three months.
The samplers are equipped with inline charcoal traps for airborne I-131 collection. The traps were mounted such that the air flow through the charcoal was horizontal thereby allowing possible bypass flow if significant charcoal compaction were to occur over the weekly collection interval.
The licensee had been following a rigid procedure for packing the sampler with charcoal in an attempt to prevent compaction and sub-
',
sequent bypass airflow.
The licensee stated that charcoal traps would be remounted such that the air flow through the charcoal would be in a vertical direction thereby eliminating
any possibility of air channeling.

ological tower during a transition period.
The remote data recording I
and readout equipment were not operational at the time of this gd inspection. No deviations from Regulatory Guide 1.23 were noted with respect to the parameters sampled, sample locations; and instru-ment maintenance and servicing schedules.
Instrument accuracies and data recording, readout, reduction and compilation functions will be examined during a subsequent inspection.
7.
Independent Measurements The inspectors briefly discussed the independent measurements program
.as it will affect the licensee.
Capability and verification testing procedures were explained. The inspectors stated that capability testing should be completed prior to fuel loading. The licensee
.
agreed with the assessment of the inspectors that the capability
~
testing procedures should be initiated three to six months prior to the projected fuel loading date to allow sufficient time for com-pletion.
