Revision 3 09/30/77 THREE MILE ISLAND NUCLEAR STATION STATION HEALTH PHYSICS PROCEDURE 1675 RADI0 ACTIVE RELEASE RECORDS 1.0 PUR'0SE This procedure describes the accounting to be used and the records to be kept for radioactive liquid releases, gas releases, and solid waste shipments in order to comply with TMI Technical Specifications.
This procedure is closely related to HPP 1621 HPP 1621.2, HPP 1622 and HPP 1622.2.
Therefore, an understanding of the philosophy and methods presented in these precedures is desirable and will aid in interpretation of HPP 1675.
2.0 DISCUSSION 2.1 Releases covered in this procedure are tha following:
2.1.1 Liquid release from the Waste Evaporator Condensate Storage Tanks (Unit-I), Waste Evaporator Condensate Test Tanks (Unit-II) and Neutralizing Tanks (Unit-II).
2.1.2 Gas release from Waste Gas Decay Tanks.
2.1.3 Reactor Building Purge.
2.1.4 Solid or Solidified Waste Shipments.
2.1.5 Any other radio 2ctive releases from Three Mile Island Nuclear Stacion.
2.2 It is required that a report on the radioactive liquid discharges, gas discharges, and solid waste shipments from Three Mile Island be f
subm;tted to the Nuclear Reguletory Commission semiannually.
This report is required within 60 days after January 1 and July 1 of each year.
Ir order to comply with this requirement a 185 316 1.0 e

3.11.5 10CFR20 4.0 OPERATION INSTRUCTIONS NOTE:
In these procedures, when an analysis is made, and the result is less than Minimum Detectable Activity (MDA),
enter a zero for the result.
If no iaformation is required, enter N. A. (Not Applicable).
4.1 Monthly Record of Radioactive Liquid Releases (Form 1675-1 Attached 4.1.1 Information required on this form is obtained from the forms contained in HPP 1621.2 and HPP 1621.
Entries are made at each release and summarized monthly.
4.1.2 Release numbers are assigned every release.
The numbering (A) system employed is as follows:
1 I - L 1 II - L Where the first digit (s) represent the number of the release (to be numbered sequentially) and the middle two digits represent the year of the release and the Roman numerals represent the Unit performing the discharge and the letter represents Liquid (to distinguish this release from a gaseous release).
This number must be entered onto the form in line A at the time of reauest of release.
Release numbers will only be assigned to Waste Evaporator Condensate Storage Tanks (Unit-I), Laund y
?
Waste Storage Tank (Unit-I), Waste Evaporator Condensate Test Tanks (Unit-II), and Neutralizing Tanks (Unit-II).

If the tank is not to be released using the radiological analyses made after assignment of the release number, then cancel the release number by entering " release cancelled" on line C.
A new release number will be assigned when a new request for release is made by the Shift Supervisor.
4.1.5 The purpose of tnis entry is to provide for summation of the tctal activity released.
For the purposes of Regulatory Guide 1.21 (forms HPP 1675-3 & 4) Gross Radioactivity (S, y) is the sum of all releases, except Noble Gasses, Tritium, and alpha emitters.
(la)
Complete Item 1 only if a gross e analysis is required to be performed, and if a specific isotopic analysis has not been pe rfo rmed.
Gross s analysis are required for the Laundry Waste Storage Tank, and Monthly Surveillance Checks on unmonitored release paths.
Item la for the Laundry Waste Storage Tank is from ([d of 1621-3.
For unmonitored release paths, la is the product of specific activity and reler.se volume.
These are obtained from 1776 and must be dimensionally correct to yield the result in Curies.
At the end of the month, an entry is made in the last column for la, which is the sum of all la entries and all item 7 4.0 I

i entires (except noble gasses).
(lb) lb is calculated at the end of the month by dividing the la total (see above) by the Total Dilution Flow (item 6 times 1000 to convcri to ml).
(Ic)
Item Ic is calculated for each release.
For Laundry Waste Storage Tank divide Activity (item la) in the sample by the Total Dilution Flow (section h of 1621-4 converted to ml).
For Waste Evaporator Condensate Storage Taks (Unit-I), Waste Evaporator Ccndensate Test Tanks (Unit-II) or Neutralizing Tanks (Unit-II) divide the sum of all item 7 entries (times 6
10 to convert to uCi) by the Total Dilution Flow (section @
of 1621-4 or Section @ of 1621.2-4).
4.1.6 Complete Part 2a by transferring the H released from @ of (2a) 1621-3 or.1621.2-3.
2b is completed at the end of the month
(?b) by dividing the total of all 2a entries by the total dilution flow in the month (from item 6 total times 1000 to convert to ml).
4.1.6.1 The purpose of this entry is to provide a total of all noble (3a) gas radionuclides released.
Complete part 3a at the end of the month by entering the sum of all noble gas radionuclides identified in part 7 of 1675-1 (135Xe, 133Xe, 4I.h Kr, 85 etc.).
(3b)
Complete part 3b at the end of the month by entering the tum T

Revision 4 09/30/77 4.1.8 For batch releases, complete part S by entering the Actual (5)
Volume released frcm (E) of 1621-3 or 1621.2-3 divided by 1000 to convert te liters.
For non batch releases (unmonitored release paths, surveillance procedures, accidental releases, etc.) ot.tain estimate of volume released from HPP 1776, or in the case of accidental releases from the Shift Supervisor.
4.1.9 Complete 6 at the end of the month by entering the total (6)
MDCT Effluent during the month.
The Total MDCT Effluent (dilution flow) for all liquid radioactive released to the Susquehanna River is octained by subtracting the MDCT totalizer at the beginning of the month from the value at the end of the month. Alternately, the value can be obtained by summation of the product of MDCT Effluent flow rate times the amount of time at that flow rate for the mor.th.
The MDCT flow rate strip chart recorder and MDCT Totali er are located in the z
Control Room.
4.1.10 Complete ecch entry of 7 by transferring the appropriate value (7) from ([) of 1621-3 or 1621.2-3.
Enter any additional isotope; and quantities found.
4.1.17 For each release complete item D by summing all the entries in (D) items la, 4a, and all item 7 entries (except Kr, Xe, and Ar Isotopes).
4.1.12 For each release complete item 8 by entering the product of (8) item D x 100 divided by 10 Ci.
4.1,13 For each release complete item E by entering the product of (E) item D x 100 divided by 2.5 Ci.

4.2.10 Complete Item 6 for batch releases only by entering the prc Juct (6) of the sum of tioble Gas Specific Activities in pCi/ from@ of 1622-3 or 1622.2-2 times Actual Release Rate from @ of 1622-4 orfrom@of 1622.2-3 or from of 1622.2-4 (to convert CFM to cc/sec, multiph CFM times 472).
4.2.11 Complete Item 7 after completion of Item E in this form.
(7a,b) 7.a is k of E.2, 7.b is b of E.1.
NOTE:
TMI policy is to maintain all releases as low as practicable.
Therefore, a working quarterly average limit is established as the quantity in the Environmental Tech Spec's which if exceeded requires notification
.of the NRC within 30 days.
This value is 4 of the maximum which can be released per quarter. Refer to HPP 1675 or the Environmental Tech Spec's if more clarification is desired.
4.2.12 Complete Item 8 by entering the actual quantities released of each nuclide (in Curies) from the following:
Particulates and Iodines - Unit Vent Sampling Noble Gases - @ of 1622-3 or 1622.2-2 and @ of 1622-5 cr 1622.2-4.
4.2.13 Item D is not applicabl' for batch releases as this value is already calculated in HPP 1622 or 1622.2.
For all other entries not covered by gaseous release permits and for which HPP 1622 or 1622.2 has not been completed, calculate as follows:
D.1 (for Iodines + Particulates) = h(SA)(V) j D.2 (for Noble Gases (SA ) (V)

= Maximum Permissible Concentration from 10CFR20. App. 9, Table II, Col.1.
NOTE:
Value in D.2 is analagous to the number of cc's of MPC equivalent air.
For batch releases, the data from @ of 1622-4 or 1622.2-3 4.2.14 must be corrected from estimated data to actual data as follows:
E.1 - See "other releases" as stated below.
E.2 - h of 1622-4 or 1622.2-3 for N. Gases X 44 of 1622-3 or 1622.2-2 + h a of 1622-1 or 1622.2 1 For releases (as mentioned in 4.2.3) calculate as follows:
