Dose assessment methodology.
All parties interviewed were well pleased with the day to day interactions concerning emergency preparedness.
The following items were identified for correction or improvement:
1.
Uhtle agreeing with the contents of the public information brochures, the Bureau of Radiation Control feels the information could be presented more effectively.
(They referenced the South Texas Project's Emergency Planning Calendar.)
2.
The Somervell County Judge feels that some areas are not adequately covered by the siren system.
3.
Test results from the Alert and Notification System needs to be sent to both counties and to the Bureau of Radiation Control.
4 Most interviewees felt that the information flow during drills and exercises could be improved.
Examples:
Telecopies to the Division of Emergency Management were illegible a.
during past drills.
b.
Event description is almost always left blank (what is happening in the plant).
A Standardized Notification Message form was agreed to by CPSES, c.
South Texas Project, and state authorities but CPSES has yet to implement, d.
There is a glaring lack of attention to detail in information sent to the Bureau of Radiation Control (see item 7 from the Bureau's critique of the March 7, 1989 drill attached).
l
. The County Judge generally felt both content and frequency could e.
be improved.
5.
The Division of Emergency Management felt that recently instituted quarterly meetings between the two nuclear utilities and state emergency response personnel should clear up scheduling difficulties previously observed.
l 6.
As in previous drills and exercises, there were some problems associated with how the notification message forms were filled out by the players at CPSES.
For example, af ter the March 7,1989 exercise, the following comments were provided by the State Bureau of Radiation Control:
On message number 1, no meteorological data was provided.
a.
b.
On message number 2, the temperature at 60 meters was not provided.
Instead, the block was marked N/A.
If N/A means not available we must ask why the 60 meter temperature was not available for the second message, but suddenly became available for message number 37 If, on the other hand. N/A was intended to 33
,-e
-n---,,,-n
r
- Attachment 1 to TXX 89684 Septemb;r 14. 1989 PCee 3 of 4 mean not. applicable then we must point out that it is not the prerogative of onsite personnel to make that determination.
The
.. content of the message form consists of data elements which we feel we need and which, by incorporation in plant emergency
- en procedures TU Electric bas agreed.co provided. Neither your communicators nor your Emergency Director should be allowed to think that they are at liberty to second guess this agreement.
On message number 2, wind speed was given as 7 miles per hour or c,
4.47 meters per second.
On message number 3, wind speed was again given as 7 miles per hour, but the meters.per second rate was given as 3.1 meters per second.
Since the meters per second value is calculated by multiplying speed in miles per hour by.447, we question the math used in calculatir.g the 4.47 meters per second speed reported on message number 2.
This may seen like a minor issue, but similar math errors in other portions of the message could have very serious consequsnees, d.
On a similar vein, wind direction on message number 2 was reported as being from 50 degrees.
On message number 3, the wind direction was reported as being from 0.50 degrees. Was this a 49.5 degree error or had the wind actually shifted by 49.5 degrees between message number 2 and message number 37 Don't place us in the position of having to guess when you mean what you say and when you really mean something else, e.
Except for the notation "same as in previous message" no meteorological data was given on message r. umbers 4 and 5.
This was especially disconcerting because message number 4 presented us with a release in progress and' raised the event severity level to Site Area Emergency at a time when we were already unsure of the wind direction.
(
f.
Another discrepancy which was minor but glaring on message number
)
4 was the fact that the message said the SITE AREA EMERGENCY was i-declared at 0955 because of a radiological release which didn't start until 0956.
On the message number 4 form, a time of 0941 or 0947 had 3.
previously been entered for the event declaration, but that time was lined through and a new time of 0955 was entered.
The disturbing thing about this alteration is that two messages later the start time of the release was changed to 0940.
What really happened here? Was the time of event declaration altered on message number 4 so that the notification message approval time of 1001 would be within 15 minutes of the event declaration time?
If so, they still missed the 15 minute deadline by 1 minute, h.
Not once on any of the notification messages were affected sectors (item 5.E) indicated. Where the line wasn't simply lef t blank, it was marked N/A.
Since the only thing necessary to 34

Page 4 of 4 determine the affected sectors was the wind direction, this use of N/A obviously was to denote not applicable *. Our reaction to a
this is the same as in comment number 2 above.
l
- m e.
.1.
On message number 6, the stability class was suddenly changed from i
D to E.
Since there was no change in wind speed, only a 1 degree (we think) change in wind direction, only a 1 degree change in 10 i
meter temperature, and no data provided for 60 meter temperature, we have no basis for judging whether this was a valid change, a change made in error, or a previous error being finally corrected.
- j. Message number 6 announced the declaration of a General Emergency
[
at 1053. This message was not approved by the Energency Coordinator until 1117; well outside of the fifteen minute deadline for offsite notification following declaration of an emergency classification.
i k.
On message numbers 6, 7 and 8, the declared time of the accident classification was consistently reported as being 1053 Message number 9. however, reported that time as being 1330, with no change in accident classification and no explanation of the switch to a 1330 declaration time.
1 1
1.
Temperature at 60 meters was only given once, on message number 3.
We never did receive a message notifying us that the drill was m.
over, or that the event had been terminated.
Such chronic problems with the notification messages should have been l
detected and corrected before the approval of the gaergency Coordinator was
-obtained. Many of these errors and omissions might never have occurred if plant personnel better understood that accurate and complete information is essential in formulating and directing offsite protective response.

l Status of Corrective Actions
}
l CPSES has recently published a new information booklet that more l
t 1.
effectively presents emergency related information, j
2.
As a result of subsequent discussions with county officials, CPSES personnel will continue to ensure that all residents of the 10 mile Emergency Planning Zone can be alerted in the event of an emergency.
If areas are discovered that are not adequately covered, additional sirens i
or other means will be used to notify those residents.
3.
The County Sheriffs for Hood and Somervell are already notified when discrepancies are identified during the monthly Alert and Notification System testing. The Texas Division of Emergency Management will be
~,
requested to provide the quarterly summary from the Alert and Notification System tests to both counties and the Bureau of Radiation control.
4.
Considerable training was devoted to CPSES staff concerning the importance of information flow.
Much improvement has been attained as was demonstrated in the Graded Exercise on July 25, 1989.
S.
The quarterly planning meetings between State emergency response personnel, CPSES, and the South Texas Project have enabled two year schedules to be developed.
6.
All personnel at CPSES involved with the notification message process received additional training on the importance of communication and notification.
During the Graded Exercise on July 25, 1989. with the exception of one message form, all messages were legible, complete. and contained accurate information.
The problem with the one message was due to the difficult nature of the exercise, and corrective action will be taken to prevent recurrence.
