Public Information Officer / Unified Dose Assessment Center Drill'
The licensee held > a drill on December 5,1985, to demonstrate the
adequacy of the telec'opy system and to provide training for SMUD and
county Public Information Officers-(PI0s).
Drill participants: included re'presentatives and PIOS from SHUD, the State
of California, and the counties of Amador, San Joaquin, and Sacramento.
The portions of the drill that involved participation by the offsite
agencies is under-the purview of the Federal Emergency Management Agency
and these portions were not evaluated by this agency.
The following observations were made by the NRC inspector in the EOF
during.the drill.'-
a)
News releases transferred to th'e Emergency News Center (ENC) were
~
accurate and timely.
b)
There were adequate facilities available for the transfer of
informational releases to the ENC and for communication between
local and state officials.
c)
News releases for the licensee were properly authorized prior to
their distribution.
d)
Periodic news' updates were released to keep individuals in the ENC
informed of plant status.
No violations or deficiencies were identified in the review of this
program area.

Followup on Previously Identified Items
(0 pen) 50-312/85-05-02, Review Improvements to the Meteorology Program
'
10 CFR 50 requires adequate provisions for determining the magnitude of
~
.and for continually accessing the impact of a release of radioactive
j

-
.
materials. An adequate meteorological program is necessary to satisfy
this requirement.
NRC inspection report 50-312/85-05 describes a historical review of
problems with the meteorological program and corrective actions to
resolve them. The inspection report also documented that some areas of
the licensee's meteorological measurements program (MMP) still required
further effort. Subsequent to that report the licensee met with the NRC
(August 12, 1985) to discuss their plans for resolving problems in the
MMP and introduced a meteorological consultant hired to evalute the MMP
and to make recommendations for its improvement.
.
The MMP was again reviewed during this inspection. From this review it
appears that the liceasee has expended considerable' effort to eliminate
discrepancies in meteorological data. Acti,ons taken to. improve the MMP
included the installation of a redesigned temperatuce and delta
temperature module, insulating the meteorological equipment enclosure and
providing temperature stabilization', moving' wind indication and
temperature sensors, upgrading'and implementing new procedures,
i
installing precipitation instrumentation and. replacing all four
temperature sensors.
'
The licensee has also included the MMP into the Management Safety Review
_
Committee audit list and performed'its first audit on the system with the
help of the newly acquired consulting meteorologist. Audit No. 0-745 was
performed on October 11, 1985', and documented improvements, in the
licensee's MMP. However, according to the audit, discrepancies still
exist between the primary and backup channel temperature instrumentation
at the 60 meter level.
In summary the licensee has made considerable improvements in the
meteorological measurements program. Apparently, the only areas
requiring additional improvement and further investigation are the delta
temperature instrumentation and the inconsistency between the two sets of
temperature instrumentation (primary and backup). The licensee is trying
to acquire four matched temperature sensors to replace the present
sensors. Once the new sensors have been acquired and installed, this
area will be reevaluated by the NRC. This item is still considered open.
4.
Exit Interview
An exit interview was held on December 6, 1985. During this meeting the
licensee was informed of the preliminary findings of this inspection.
There were no violations of NRC requirements identified within the scope
of this inspection. The following items were specifically discussed.
a)
The results of the PIO drill indicated that the SMUD PIO was capable
of performing his duties during an emergency and that facilities
available were adequate.
b)
Although the licensee has put considerable effort towards
improvements in the MMP, inconsistencies between the primary and
backup temperature sensors still exist. The licensee is still
investigating improvements to resolve this problem.
