- On Monday, May 1,1989, members of the Region'V st(ff and SMUD met at 10:00 L,m
A'.M..:in the Chief of Emergency Preparedness & Radiological Protection Branch's office. The_ purpose of this. meeting was to discuss the status of the licensee's H
E&WMP and for the licensee to explain administrative changes and some certain L

LThe information pertaining to the E&WMP addressed at.the meeting is included
.in the attachment.
'i Mr. Wolfe briefly described the status of the E&WMP as outlined in the'
.. attachment. Regarding Item 2A. of the attachment involving the RHUT Demineralizer Enclosure, Mr. Yuhas stated that the licensee's statement that
.the enclosure, which consists of a plastic curtain around the system, would prevent uncontrolled releases to the environment was an overstatement. The lic.ensee representatives acknowledged this observation.

' ~ Mr. Orthen informed the Region V staff that two new appendices were added to the ARE0R. These new appendices are Appendix H Radiation and Nuclear Power, f
and Appendix I, Environmental Monitoring Program Design. Mr. Orthen also
' stated that the predicted organ dose based on the 1988 liquid source term L
exceeded the calculated dose based on environmental measurements by j
l approximately 60%. This observed difference is attributed to the conservatism in the licensee's-liquid effluent dose calculations program. The licensee's.
identification of Co-60 and H-3 in well water samples were also discussed.
The licensee stated that the 1988 ARE0R contains details on the subjects.
. discussed at the meeting.
y l
Mr.- Yuhas stated that the NRC's review of the ARE0R would be a. subject of a future inspection.

BASIN DISCHARGE VALVE UPORADE Manual discharge valves for release r
or retention basins to the creek are single isolation butterfly valves. A valve leak would result in an uncontrolled release and, therefore, a valve change or the addition of blind flanges will be made..
4 STATUS:
Design engineering is complete. Blind flanges will be added. Field work should be completed by early May 1989.
i 7A.
EFFLUENT FLOW INSTRUMENTATION UPORADE Due to the high
{
maintenance and questionable reliability of existing flow instrumentation an upgrade j
to all effluent flow devices will be made.

operating servica conditions and required pump capacities. New l
pumps were procured, installed and tested. Testing indicated that the '
new pumps (the second set) were not suitable for the application.

and contain temporary routing of liquid runoffs. An upgrade to minimize to i
propensity for spills and to ensure that any contaminated system leakage is directed 1
to the RHUTs or radwaste system is being made.
STATUS:
Feasibility study as well as conceptual ennineerinn is complete.
Detailed engineering is in progress and slated for completion in June 1989. Field installation will be treated as non outage work and
{
accomplished so as to not interfere with the refueling outage effort.
i e
Completion is targeted in early 1990.
1 12A. MISC HAZARDOUS MATERIALSITE UPGRADE An evaluation of hazardous material storage locations and outdoor usage and handling particularly in light of potentially uncontrolled offsite leakage through the storm drain system is being conducted. Appropriate follow up action will subsequently take place.
STATUS:

Water Management).
13A. CHIDRINATION SYSTEM UPGRADE The Sewage Treatment Effluent Chlorination system needs to be upgraded. Current system does not have desired degree of redundancy, i
STATUS:
A temporary modification utilizing Hypochlorite to provide short term redundancy is being installed and scheduled for completion by 5/5/89.
An engineering evaluation for a permanent system upgrade is also in progress and scheduled for completion in August 1989.
