NRC Emergency Preparedness Appraisal Team Notification of Completed Actions for January 15, 1982 o
R.E. Ginna Nuclear Fower Plant Do'cket No. 50-244
Dear Mr. Haynes :
This letter is submitted in accordance with your December 15,
. 1981 letter relative to the above stated subject which requires in part that your office be informed in writing when each of the aforementio'ned actions have been completed.
Ad ditional ly, tiiis letter will refer to telephone conversions between certain members of my staff and yours regarding updated target dates for certain items in your December 15, 1981 letter.
On January 15, 1932, your Mr. Nemen M. Terc, Appraisal Team Lead-er, was inforpe'd by Mr. Lee Lang and Mr. Bruce Snow via telephone 3
regarding odrcJanuary 15, 1982 committments.
K

The following summarizes the results of that-telephone conversa-tion:
?
Regarding item 3 which states:
'A
" Realign the emergency plan training program to be consistent with the functional area, requirements, and structure of the
((
' emergency organization.
30 5 This will be accomplished no later than January 15, 1982."
a
- s This was completed prior to. January 15, 1982.
\\
Regarding item 4 which states:
[
~
. emergency duties have been trained and have attained a minimum
>" Develop and implement means to verify that all individuals with l gu level of proficieny.
This shall include but not be limited to
'" hands-on training and walk-throughs.
T
-This will be accomplished no later than January 15, 1982."

\\
4-C'
'" Complete-theLintarim installation and testing of equipment in-the Technical Support Center to ensure that it will'be habitable and functional,-and able to perform its intended use during the various-accident conditions.
t tThis will'be accomplished no later than January 15, 1982."
Th'e Technical Support Center filtration system was completed prior to January 15,1982.
Regarding item'6, which states:
"Re-evaluate provisions to rapidly and accurately detect and measure radioiodine concentration under field conditions in'the preience of noble gases, including equipment and procedunee need-ed stoc ancertain the location and characteristics of the plume relative to the sampling locations.
Provide a written report'.of tho; results of your evaluation to the NRC Region-I Office and u
include a schedule for any planned actions.
3 This-will be accomplished no later than January 15,-1982."
i This item was completed prior to January 15, 1982.
The following will constitute the above written report.
The equipment we currently use for field radiciodine determina-
- tion should perform the function of rapidly and accurately moni-
~toring radioiodine under field conditions.
The use of thc. silver seolite collection me dia, the Radeco "medi-um" volume sampler (1.5 CFM) and the RM-14/HP 190 counting system allows. good flexibility and simple-operation in the field.
The detectable range for this system covers a broad range ofL lodine concencrations which include the various protective action
. guide " signal"~ concentrations.
For the predesignate
' procedure,the-detectablerangeextendsfrom2-x10g. sampling to 3 x 10-5 uC1/ce'(12 mrem to 18' Rem adult two hour thyroid dose)!~~The
- upper range can be extended to 3 x'10-4 uCi/cc-(70 Rem. adult-two houranthyroid dose) by1 reducing the -sample. time to one minute.
This concentration of radioiodine exceeds -the highest PAG signal ~
concentration by.nearly a factor of. three, so if the concentra -
tion was: higher-for immediate actions, theiactual cencentration would-be-meaningless.
NOTE: MSie iodine' dose rates were determined using'thefEPA 520-manual of Protective Action Guides and Protective Actions
- for Nuclear Incidents (2/80).

"Re-evaluate interim _ facilities, equipment and procedures for
. post-accident' sampling and analysis of the containment. atmosphere to determine maximum concentrations that could be handled and
- analyzed during accident conditions.
Provide a written. report of the -results of your' evaluation to the NRC Region I Office and include a schedule for any planned actions.
This will be accomplished no later than January 15, 1982."
This.was completed prior to-January 15, 1982.
The following' constitutes the above mentioned report regarding the results'or.our evaluation.
The previous system which utilized a glass sample bomb has been replaced with a steel' cylinder, solid tubing and quick disconnects.
This was done to insure the-ability to sample containment if_it was pressurized above atmospheric pressure.
The containment: samples will be counted on the equipment which will handle the activity present in the sample.
The counting
- equipment normally ' used for HP and Chem. samples can be used if the sample bomb doseirate is less than 10 mr/hr on contact.
Samples above_that dose rate can be counted on the extended shelves calibrated for the accident samples.
The extended
^
shelves. can tua used for samples reading up to 600 mr/hr contact
~
- for direct counting of the sample.
If the particulate filtee of' the iodine cartridge exceeds 600 mr/hr on contact, a. reduced porticn_of the entire sample can be taken which can be handled and counted.
This can'be done by taking punchings from the filter and assuniing :the punching to be representative of the total activity 1 of the filter.
The iodine: cartridge can be thoroughly l mixed and-a portion weighed and counted.
The counted' portion lcan belassumed to'be representative of the entire sample.
1Nu3-calculated maximum concentration of the isotopes Xe-133, 'Xe-1135 and I-131 assuming counting rates of 1800 counts per second
.using. the extended shelves only are:
X3-133 4600:uci/ sample XE-135; 2500 uci/ sample
~ I-131 3660 uC1/ sample:
To further. in' crease our ability to sample;and analyze accident -
samples, a Post - Accident Sample System isi currently.being~ built, and is acheduled for -installation by June 1,1982.

oATE Ronald C. Haynes To Regarding item 8, which states:
" Undertake and complete a review of all emergency plan implemen-ting procedures and make appropriate revisions to:
a)
Clarify required actions, and eliminate existing ambiguities, inconsistencies and errors.
b)
Clarify duties and responsibilities of personnel involved in the various actions.
c)
Provide specific cross-references to other procedures in the action steps as needed to detail and clarify further actions.
The above revision shall be perforned in accordanct with a sched-ule as follows:
Procedures SC-1.2A, SC-1.2B, SC-1.3A, SC-1 38, SC-1 30, SC-1.3D, SC-1 3E, SC-1.4, SC-1 7B, SC-1 7D, SC-1.7F, SC-1 7H, SC-1.13 to be revised no later than January 15, 1982."
During the January 15, 1982 telephone conversation, my staff stated that not all procedures listed above were complete.
The work load required to complete such a total review was underesti-mated due to subsequent identified procedure interfaces.
A new target date for corapletion of the above liated procedures of w-Fe b rua ry 8, 1982 was agreed upon by ny staff and yours.
On February 9,1982 a second telephone conversation was conducted between your Mr. Crocker and Mr. Snow and "r.
Morrill.
During this discussion Mr. Crocker was advised that all mentioned proce-dures were reviewed and written, but not all had been fornally
?
processed through the Plant Operations Review Committee.
The delay was caused by the Steam Generator Tube Rupture Event and resultant change in priorities of personnel involved.
c A target completion date for PORC review and approval was agreed to by both parties.
We will continue to keep you informed as the remaining items of your December 15, 1981, letter are addressed.
I Very truly yours,
