2.0 Operational Status of the Emergency Preparedness Program
2.1 Public Alert and Notification System
\\
.
!
New Hampshire Yankee has designed a Vehicular Alert'and
~
Notification System (VANS) to notify the public in the event of an
accident at Stabrook Station. VANS is specifically utilized for-
'
the Emergency Planning Zone communities in.the Commonwealth of.
,
i..
"
The licensee performed a siren coverage acoustic analysis to determine 60 dBC and 70 dBC sound contours for all acoustic
'
locations ~. The model utilized accounts for siren rating, tone frequency, siren height and location, topographical features, and environmental conditions. The analysis identified those areas withir. the required 60 and 70 dBC -sound coverage locations, at well as those areas beyond the 60 dBC sound coverage. All: areas of the EPZ fall into the 60 dBC sound coverage, or'70 dBC.sou'id coverage for high oopulation areas, except for.four areas..These areas have been veri'fied as-unpopulated. Additional measures.have.been implemented to ensure periodic' reassessment.
The system will consist of 16 dual Whelen WS-4000 sirens. These sirens are raised and supported by a truck mounted, hydraulic i
telescoping' crane. The truck is equipped with a
'
to ensure a constant supply of electrical power. portable generator The sirens are casable of remote activation, as well as manual activation at the velicle. The siren activation si while the vehicle-is in transit. gnal will be: received and stored
,
In this case,' the sirens will d
e activate as soon as the Mast is raised to its. vertical position.'

The VANS vehicles will be stored and dispatched from six staging areas in or near the Massachusetts EPZ. These staging areas will be manned by trained drivers 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> a day, seven days a week.
The staging areas will be provided with appropriate electrical and communications equipment to ensure continuous operations.
The inspector observed a demonstration of a VANS truck dispatch and setup. The operator was well trained and performed the setup in an expeditious manner. The sirens were not sounded for this test.
Additionally, the inspector visited each staging area and subsequently ran each of the sixteen routes from the' staging area to the acoustical areas. The time required to run each of these routes, plus average dispatch and setup time, can be accomplished within 15 minutes.
The licensee has also compiled statistics for the routes under varying weather, time of day and time of week conditions. These data indicate that sireas can be sounded for each acoustical area within 15 minutes.
Supplemental equipment will include six backup vehicles.
Four will be available to compensate for equipment failure, with two vehicles in maintenance and surveillance. A full inventory of spare parts will be maintained. One helicopter is available as a backup in case of an impediment preventing a truck from reaching its acoustical area.
The licensee plans to have this system in place by August 5, 1988 utilizing leased vehicles.
These leased vehicles, as well as the spares, will be phased in with purchased vehicles by October 15, 1988. A FEMA-REP-10 design report was forwarded to FEMA for formal review on Apr's 1, 1988.
3.0 Exit Meeting
,

'
system, it no time during this inspection did the inspectors provide any written i
