EPP-6
-3 June 1983
5.1.4 Prior to.
leaving equipment storage location, obtain,necessary communicatione equipment and assure its operability by establishing communications with the TSC.
Inplant survey teams will utilize radio chmmel #1 (Inhouse repeater) and will be identified by numerical designations (ie. Inplant 1,2,3, etc.).
5.1.5 When accompanying Damage Control Teams, verify that a Radiation Work -
Permit has been written and that team members are properly outfitted with protective gear and dosimetry.
5.1.6 When conducting surveys separate from Damage Control Team entries, proceed to the locations requiring monitoring per step 5.1.1, and use appropriate station floor plans and survey forms contained in the Inplant Emergency Survey Binder to record results.
Furthermore, ensure that a HRA Entry and Survey Log or a Radiation Work Permit is filled out to record exposures of survey team members.
5.1.7 If airborne activity is suspected because of:
A ventilation monitor in the alarm condition, or a.
b.
A CAM in the alarm condition, or c.
Visual observations detect the presence of steam which could be radioactive then:
Full protective clothing including Scott Air Paks should be donned.
5.1.8 a.
If the survey consists of taking radiation measurements on the stack sample line when the stack monitor is approaching its limit per N1-PSP-12, ensure the 4 "C"
cell batteries designated for use as spares in the installed interim High Range Stock Monitor are brought from the Control Room Dose Estimate Cabinet or Station Storeroom to the 256' elevation of the Screenhouse, b.
When entering an area of suspected radiation, the survey meters (normal and high level) should first be on the highest range of the instrument, then downscaled until a reading is obtained.
The Teletector Probe should be extended so that distance can be put between the surveyor and the probe.
i c.
When conducting surveys, voice communications (e.g.
- radio, Gaitronics, etc.) with the TSC or Control Room should be
- 7 i
l maintained as appropriate.
In addition, when approaching an area requiring monitoring, do not approach the level via the l
elevator. Use stairs only.
3.1.9 a.
The area should be entered cautiously making observations of any failed equipment which could have caused the alarm, b.
Survey area to verify validity of monitor readings as per RP-3
" Performance of Radiological Surveys".
Survey the area as quickly as possible to ascertain the cause of the high radiation.
Note any unanticipated high radiation levels, their location, and time and date of reading.
4 NOTE:
Keying a radio microphone close to a RO-2A dose rate meter may cause an upscale deflection of that instrument.
If this should happen, repeat survey maintaining an adequate distance between microphone and dose rate meter.
EPP-6
-4 June 1983
5.1.10 If dose rates greater than 10,000 mrem /hr are encountered, exit immediately and report results to the S tation Survey / Sample Team Coordinator, per Step 5.1.1, or others, as directed.
Area should be reentered only after a survey planning session has been held per EPP-15.
5.1.11 If airborne activity is suspected, a high volume air sample vill be taken in the suspected area (2 to 10 micute Particulate and Iodine sample) as per N1-RTP-75.
Record flow rate and the time the sample is started and stopped on Figure 1.
If field analysis is possible continue with Step 5.1.12, if not sMip to Step 5.1.13.
5.1.12 After obtaining samples, travel to an area of low background (preferably < 300 cpm but not to exceed 500 cpm) and run high volume air sampler for approximately 1 minute to clear inert gases from the cartridge.
NOTE:
If sample (s) have been taken on Silver Zeolite Cartridges (s) the post sampling purge is not required.
Obtain a background count and count the particulate filter and lodine cartridge separetly.
During counting hold the probe approximately 1/2 to 3/4 inch from the cartridge or filter and count for a total I
time of 1 minute.
Log the maximum count rates obse ved en the survey 7
data sheet (Figure 1).
5.1.13 The results of all surveys shall be immediately recorded on Figure j
1.0 and reported (via radio, Gaitronics, etc.)
to the Station i
Survey / Sample Team Coordinator in the TSC or the SSS in the Control l
Room, as appropriate, so that proper evaluation can be made of the i
conditions.
This data will be logged on Figure 2 and provided to l
l appropriate survey coordinator for review, posting and action.
l 5.1.14 Filters, cartridges and/or liquid samples shall be placed in separate l
containers (e.g.
envelopes, plastic bags, etc.)
to avoid cross j
contamination of samples and counting facilities.

5.1.7 Samples / Measurements a.
_s, f Dois Rate Measurements i
Two different readings (ground level and waist level) are taken at each survey point.
These two readings should assist in the i
evaluation of whether the activity is coming from an overhead plume or a ground deposit. Reading will be taken after the air sample has been started at a given location, if an air sample is required.
Ground Level Readings Ground level contact readings should be taken at three survey points within a circle of about 25 yards in diameter using a c)unt rate meter. Readings over 20,000 c/m should be taken with a dose rate meter. Record open window and closed window readings.
Record and report only the highest of the three measurements.
Waist Level Readings Waist level readings (approximately 3 ft from the ground) should be at each of the locations where a ground level reading is taken._
Readings over 20,000. c/m should be taken with a dose rate meter. Record open window and close window readings.
Record and report only the hi:; hest of the three measurements.
b.
Air Sample Measurements Air samples should be obtained at the plume centerline and at k
other locations, as specified' (ie plume edge).
Other air samples should be collected for backup data after the primary sampling is completed.
Using a portable high volume air sampler (AC or DC depending on power source) loaded with both particulate filter and iodine collection cartridge, obtain a 5-20 minute sample (approximately 15 cubic feet).
Record flow rate and the time the sampler is started and stopped.
NOTE:
Silver Zeolite sampling cartridges shall be used until it has been determined that noble gas interference of air samples measurementa is not a problem.
Sample filters, cartridges and/or liquid samples shall be placed in separate containers (e.g. envelopes, plastic bags, etc.) to avoid cross contamination of samples and counting facilities.
After obtaining air samples, travel to an area of low background
( <100 cpa) and run the high volume air saapier for approximately 1 minute to clear inert gases from the cartridge.
f NOTE:
If sample (s) have been taken on Silver Zeolite Cartridge (s) the post sampling purge is not required.

6 5.2.6 Guidelines for field monitoring a.
Upon discussion with the Radiological Assessment Coordinator provide recommended locations for initial and fonow-up field monitoring to survey teams.
These should be determined based upon prevailing wind directions, and survey / sample locations, i
and/or roads in that direction.
Furthermore, should effluent l
monitor data not be readily available, establish what survey I
location (s) will be used to determine chronological release rate l

b.
Monitoring' should be performed over a three sector area '(e.g. -
that is one 22 1/2" sector on each side of the affected sector) 6 until the puas centerline has been established off-site.
NOTE:-
During lake breeze conditions, it is possible for the plume to diverge from the prevailing costal wind direction once it meets the inland air mass.
Therefore, during postulated lake breeze conditions (i.e. wind direction from north) it may be necessary 0
to expand survey area to 45 on either side of the plume sector in order to define the inland direction of plume.
Advise survey teams whenever it appear's that the wind direction c.
has shifted more than 22 1/2* during the monitoring period.
d.
Direct, if necessary, survey teams to collect and replace azisting emergency and environmental T1D's, beginning with the T1D's downwind of the plume.
e.
- Direct, if necessary, the-initiation of the expanded environmental monitoring program based on the release conditions (n.g. water for liquid releases, grass and milk samples for 6
iodine releases).
5.2.7 As survey results are received via the survey Report Form (Fig. 2),
calculate dose rates and airborne concentrations using Fig. 2 and v) forward data to the Radiological Assessment Coordinator.
Perform an evaluation of the following areas per each location.
a.
The whole body immersion dose rate will be due mainly to noble gases.
This may best be estimated by the waist (3') dose rate reading directly in mR/hr.
b.
Noble gas airborne. activity any be calculated using the following formula:
