INVESTIGATION REPORT EAST KINGSTON JANUARY 31, 1987 SIREN TEST (ver. 2/20/87)
EXECUTIVE
SUMMARY
The Civil Defense Director, Town of East Kingston, conducted an emergency communications test on January 31, 1987 between 9:30 am and 1:00 pm.
The test included activation of the Civil Defense, Fire Department, and Police Department pagers and the four sirens (part of the Seabrook Station Public Alert and Notifi-cation System) located in East Kingston. The test of the pagers was entirely successful.
The test of the four sirens pointed out the following potential problem areas that need to be evaluated ar.d the appropriate corrective actions taken:
a) lack of test procedures b) apparent siren activation failures c) perceived low siren acoustical output during the test The lack of a formal test procedure resulted in several observed difficulties in conducting the test. These included insufficient time for siren rotation for each signal mode, communications difficulties with observers in the field, lack of observer identification of siren broadcast mode, lack of radio protocol and improper voice articulation using the public address mode.
Further, needed I
improvements were identified relative to specifying personnel coverage, pre-test material requirements, and providing media interface.
C/EKT.1 1
g\\
le i
i
The initial test results reported from the East Kingston Civil Defense Director indicated that one of four sirens activated from the signal sent from Rockingham County Oispatch in Brentwood (State of NH activation point), and that three of four sirens activated from the signal sent from the East Kingston Emergency Operations Center. A visual check of the antenna at the siren pole that failed to operate from both points revealed a significant snow and ice build-up. Once this was removed, the siren activated on signal. Subsequent field tests and consultation with the antenna manufacturer confirmed that the unusual amount of ice accumulation could have attenuated the electronic activation signal in communities furthest from the activation repeater and could have caused the siren to not activate reliably.
The snow and ice accumulation was caused by a severe winter storm which occurred during the night before and early morning hours on the day of the test.
Daytime temperatures during the test were below freezing, preserving the snow and ice accumulation.
The winter storm also caused snow and ice build-up on the metal screens on the front of the siren horns.
Snow was driven by 20 mph winds from the northeast into the sirens which face due north. A visual inspection of the four sirens on the day of the test revealed accumulations varying from 30% to 70% of the screen area.
This snow and ice accumulation suggested a possible degradation in the acoustical output of the sirens. Calculations provided by an acoustical consultant showed that actual sound transmission losses are highly variable and could have alone caused the reported reduction in sound level. The consultant also stated that the directivity of the sirens acoustical output signal could be impaired by snow and ice accumulation.
This opinion was confirmed by a repre-sentative from the siren manufacturer, Whelen Engineering, who was also consulted.
C/EKT.2
Immediate corrective actions are being taken for each of the identified problems.
A detailed test procedure is being prepared to ensure consistent test results.
To correct the antenna icing problem, a modified antenna is being installed that is less prone to snow and ice buildup.
Two actions are being taken to prevent siren icing.
First, based on a prelimi-nary review of the historical meteorological patterns, the sirens are now. parked with their openings in the southeast direction, 180' out of the prevailing wind direction. Second,' hydrophobic (water repellent) coatings for the siren grates are being tested.
It is expected that this coating will eliminate the buildup of wet snow on the siren grates.

Description of Test and Problems Reported East Kingston, working with New Hampshire Civil Defense and New Hampshire Yankee, scheduled a comprehensive communications and siren test for January 31, 1987.
In preparation for the test, a pre-test equipment checkout was conducted by New Hampshire Yankee and ALLCOMM, Inc. personnel on Wednesday, January 28, 1987. All components of the East Kingston siren system were extensively tested.
This included a test of both state and local activation mechanisms. These pre-tests verified that all equipment was functioning to original design specifications; however, acoustical performance was not 4
checked at this time.
On Saturday, January 31, 1987, East Kingston conducted their communications and siren test.
The communications portion of this test evaluated the initial notification pagers as outlined in the RERP.
This portion of the test was coordinated and activated from Rockingham County Dispatch and was a complete success.
The second portion of this test consisted of test activations of East Kingston sirens from both state and local activation mechanisms.
This test l
was carried out in the immediate aftermath of a severe snow storm driven by 20 mph winds which blanketed virtually all exterior components of the siren system, as well as the grate covering the siren opening, with a heavy, wet layer of snow and ice, i
The test was coordinated and carried out by East Kingston personnel. Two problems were reported during the tests.
C/EKT.4
First, initial attempts to activate the sirens were unsuccessful.
The state activation mechanism was unable to activate the sirens consistently. After a series of activation attempts from the local activation mechanism, East Kingston officials were aole to activate the sirens consistently. One siren, which appeared not to be responding to either local or state activation attempts during the early stage of the testing, was checked at the siren site with a hand held test set and it responded and functioned normally.
The antenna connection was checked and the ice and snow were removed from the antenna.
The siren was retested from both state and local activation mechanisms and it activated con-sistently for the remainder of the test.
Second, observers reported sound output from the sirens at levels less than that expected. When tested in the public address mode, three of the four sirens were reported to have produced unintelligible signals.
Following the test, East Kingston town officials identified the need for a test procedure.

II.
Problem Investioation A.
Lack of Test Procedures 1.
Test Observations During the post-test meeting, East Kingston town personnel pointed out the need for a test procedure which would include a detailed time schedule, description of each siren mode to be tested, observer location assignments and documentation.
It was also noted by NHY and ALLCOMM personnel that the town observers and EOC personnel could benefit from procedural requirements for clock synchroniza-tion, team briefing prior to test, radio operaticn protocol, siren PA mode announcement training, and specification of the time dura-tion for each siren mode activation.
It was noted during the test that some observer radio transmissions were overloading the dispatcher's ability to record data, that field teams did not have location identifiers for radio transmissions and that field reports were not given in any specific sequence, i
Following a review of the magnetic tape of siren codes transmitted, it was also noted that, both from the Rockingham County and the East Kingston activation points, the time between activations for each mode was very short (some as short as one minute), which gave insufficient time for siren horn rotation in each signal mode, field observer interpretation of the signal, reporting results i
i over the radio, and logging results.
2.
Conclusion Lack of a detailed test procedure was a significant factor in the problems noted for the test.
CEKT.6
B.
Low Siren Acoustical Output 1.
Test Observations A winter storm occurred the evening and night before the test producing 8 to 10 inches of snow in the seacoast area including East Kingston.
A review of Seabrook Station meteorological data taken during the storm and siren test (Appendix A) shows that winds were 3 to 20 mph.
During the snowfall, winds were initially frei the EaJt and gradually shifted to the North. Temperatures during the snowfall were slightly above the freezing mark. After the snow, temperatures dropped to below freezing.
Since the siren openings face North, wet snow was driven onto the outer screens where it accumulated. The subsequent temperature drop and brisk winds served to harden and pack the accumulation.
NHY observers reported that the accumulation on the siren screens and interior surface of the horn appeared to be hardened with 30% to 70% of the screen blocked. At a post-test meeting, East Kingston observers at the siren sites and in the field agreed that in their judgement the " effective range" of the sirens was approximately 200 to 300 yards. Some personnel who were in vehicles stated that the sirens could only be heard when they were stopped with the engine off and with the windows open.
Observers stationed at the sirens said that the PA voice mode was raspy, over modulated and could not be understood unless they were standing directly under the siren. Some field observers said they never heard the PA voice.
C/EKT.7
2.
Riview of Tape Loa
{
A magnetic tape record of all transmissions made on the siren activation frequency is routinely maintained by the State activation point. A review of the tape made during the test was performed.
l Only one test (Test #21) involved the ectivation of all four East Kingston sirens while broadcasting the signal intended for use during an emergency at Seabrook Station.
For that test, the sirens were activated at 11:55:50 and cleared at 11:56:15 for a total activation time of 25 seconds. Activation for that short duration was not a valid test of the warning capability of the s
The recommended duration of siren activation is 3 to 5 minutes in order to provide an effective warning signal. Complete 360* rotation of the siren was not achieved during the short activation.
Second, a detailed review of the siren activation codes trans-mitted daring the test shows that only one of the activations during the entire test placed all four sirens into the PA mode.
This was Test #17 which was initiated at 11:46:29 (RCDC time) and continued into Test #18.
Midway through Test #18, at 11:48:40, a " clear" command would have taken the sirens out of the PA mode.
During the entire time the sirens were in the PA mode, they were facing North (into the wind) and they were never moved.
In order to have the PA mode function properly, the sirens would have to be moved 45' each time the PA announcement was made. That means the sirens would have to be moved (8) times, once after each C/EKT.8
cnnouncement, to cchisvo 360* c:vsrag].
This w s not dona.
Therefore, observers located for 315* around the sirens would have been unable to hear a clear signal.
l 3.
Calculation of Acoustical Effects At the request of NHY, a recognized acoustical engineer with extensive knowledge in siren systems, performed a series of calculations to determine the potential acoustical effects from the reported ice and snow blockages.
Two effects were considered.
First, the blockage of the siren by ice was calculated. Based on its density, ice is calculated to result in a transmission loss of 38 decibels. That reduction would occur if the entire siren screen were covered.
Partial coverage of the screen as reported, would result in less attenu-ation of the siren signal. That attenuation was calculated to be from 3 decibels for 50% coverage of the screen and 6 decibels for 75% coverage of the screen.
The second effect evaluated was that of sound absorption by loose snow packed in the siren cavity.
Sound absorption for this effect is.6 to 1.5 decibels per inch of snow.
It is estimated that 3 to 4 inches of snow was present in a portion of the sirens.
Therefore, the combination of the two effects for the observed conditions could result in a 4 to 12 decibel reduction. Reduc-tions in sound levels at the upper end of the range would be significant, with the resultant sound being perceived as less than half as loud.
C/EKT-9
4.
Risults of Contact with th> Siran M*nufacturar
'The supplier of the sirens, Whelen Engineering Company, was contacted to determine whether this problem had been reported before. After extensive review of the icing problem with the Field Service Manager and Vice President, it was determined that this problem had never been reported before. They provided the names of other snowbelt utilities using the same sirens as NH Yankee's.
5.
Results of contactina other utilities Four utilities located in the snow belt were contacted. None had experienced a similar problem. However, each of the utilities contacted parked their sirens in a position so that the siren horn mouth faces opposite the prevailing wind direction. See Appendix B for the list of contacts.
6.
Conclusion Based on the weather conditions during the test, it is concluded that ice and snow buildup on the screen of the siren and in the throat of the siren caused blockage and absorption of sound.
This condition resulted from the sirens facing into the prevailing wind during the storm.
Further, when operated in both the Alert mode and public address mode, the sirens were not operated in a manner to ensure proper audibility.
l l
C.
Siren Activation Failure 1.
Test Observations On the day of the test, snow and ice built up around and on the antenna base and ground plane. Only one of four sirens activated initially upon command from the State control point.
C/EKT.10 r
From th2 local ccntrol point, thrG9 of tha fcur sircns cctivatcd.
The East Kingston-2 siren which failed to activate from either state or local activation points, was checked and activated properly from the strong signal provided by the siren test transmitter (hand-held device used at the siren site). When the ice and snow were removed from its antenna, it activated reliably from both state and local control points. This was shown by a review of magnetic tape data referenced in item II.B.2 above.
2.
Results of Contact with Antenna Manufacturer The manufacturer of the siren site antenna, Antenna Specialist Company, was contacted.
Discussions were held with members of their engineering staff.
The problem of ice and snow accumulation on the antenna and the buildup of wet snow and ice around the antenna base due to the surface area of its mounting bracket and ground plane disk was explained.
It was believed that this buildup caused antenna detuning and attenuation of the activation signals.
The siren antenna is a mobile antenna that was adapted for
" fixed" use at the siren site.
It contains a stainless steel spring designed to allow the antenna to flex in the mobile environment when it contacts external objects. This spring is electrically bypassed internally by a flexible braid. The manufacturer pointed out that, due to capillary action of the wound spring structure and conductivity of its surface, it i
exacerbated the detuning effect, f
C/EKT.11
The manufacturer confirmed that the unusual type of antenna icing that occuared detuned the antenna and effectively lowered its operating frequency. This caused attenuation of the received signal at the siren site. Because the snow was very wet and the ice was not solid and dry, its properties were closer to that of water than ice.
In the manufacturer's opinion, this unusual type of " wet" icing condition presented a near worst case of signal attenuation.
3.
Additional Antenna Manufacturer Contacts Two additional antenna manufacturers were contacted. These dis-cussions paralleled the discussions held with Antenna Specialist Company. They confirmed that the type of icing described would cause antenna detuning and signal attenuation. While neither had encountered any research on the subject, they believed that antenna icing can cause various changes in the electrical characteristics and performance of both mobile and base station antennas.
4.
Field Test Program To verify the suspected cause and severity of the antenna de-l tuning and its accompanying attenuation mechanism, extensive field tests were performed.
l The objectives of the test program were to identify the resonant frequency of the siren site antenna system both when it was dry (no ice or snow accumulation present on its surfaces), and when l
i C/EKT.12
i wet snow and icing conditions existed similar to those that existed on the day of the test; and to quantify the approximate degree of attenuation these conditions had upon any activation signal received at the siren site.
The results of these tests indicate that the unusually adverse wet snow and icing conditions similar to those that existed cr.
the day of the test would produce signal attenuation significant enough to result in unreliable siren activation.
The sirens most effected by this phenomenon would be those located furthest from the state activation transmitter which is a repeater site located in Newington, NH.
5.
Conclusion Based on manufacturer information, empirical data collected during the East Kingston test and the results of the field test -
program, it is concluded that the unusual snow and ice buildup at the antenna caused detuning and a failure of the siren site receivers to respond reliably to activation signals sent by the town and county control points.
l III. Recommended Corrective Actions A.
Lack of Test Procedures Recommendation:
A detailed test procedure should be prepared to ensure future town tests of sirens provide meaningful test results.
The test C/EKT.13 i
procedure should include personnel assignments, preplanning required, materials required and media interface requirements.
B.
Siren Icing Recommendations Short Term: NH Yankee should reorient all sirens out of the prevailing winter wind direction. A review of historical wind rose data in the Seabrook Station FSAR shows the dominant winter wind direction is from the WNW and NW (see Appendix C). Therefore, the optimum direction for orienting the sirens is with the siren opening facing toward the southeast.
It should be noted that the winter winds blow from the southeast less than 1% of the time.
Long Term: Wind data specific to winter storms with precipita-tion should be reviewed by Yankee Atomic Company meteorologists to confirm the optimum orientation of the sirens.
Further, two modifications to the siren screen should be considered.
- First, a water repellent coating, Vellox 140, should be evaluated under harsh environmental conditions for use on the existing screens.
Second, since the expanded metal design of the grating presents a significant surface area for snow accumulation, a change of grating should be evaluated.
C.
Antenna Icing Recommendation The existing antenna designs should be modified to minimize ice and snow buildup. After investigating possible improvements, it is recommended that a design similar to an Antenna Specialist ASPR-659 C/EKT.14 L
