JUSTIFICATION FOR CHANGES TO THE I

OFFSITE DOSE CALCULATION MANUAL Revision 7 General Comment:

The ODCM was changed from AP.310 to CAP-0002 to comply with new Rancho Seco procedures.

The contents were changed to e more orderly format, dose projection equations were added, I

an.1 the liquid ~ effluent monitor setpoint calculations were modified.

Therefore, although most of the calculations in the manusl-did not change, the numbering and location of cainulations did.

To provide an easy method of review, the step nacer from I

AP.310 will be referenced if a step number was changed.

ADDITIONS TO REVISION 7 S1EE The PURPOSE was reworded to coincide with the description 1.0 in Technical Specification 1.15.

This change is editorial and does not af fect the accuracy or reliability of dose calculations or setpoint determinations.

2.0 The SCOPE was also reworded to. coincide with the-3 description in Technical Specificatione.

This change is-.

editorial and does not af fact the accuracy or reliability g

of dose calculations or setpoint determinations.

3.0 The REFERENCES section was divided into a REFERENCE and COMMITMENT section.to conform to procedure guidelines.

Com;nitments and rsferences were added to ensure completeness.

This change is editorial and does not I

affect-the accuracy or reliability of dose calculations or setpoint determinations.

c F

4 '.1 The definition of REAL INDIVIDUAL was changed to MEMBER OF THE PUBLIC to coincide with-the definition in Technical Specification 1.19 and 40 CFR 190.

.The

=

definition was also expanded to clarify the difference between dose calculations for the MEMBER OF THE ~ PUBLIC and the MAXIMUM EXPOSED (HYPOTHETICAL) INDIVIDUAL.

The

7. '

MEMBER OF THE PUBLIC dose calculation will be based on actual food consumption, usage-and occupancy rates of a

' J!

real individual', whereas the MAXIMUM EXPOSED INDIVIDUAL i

will be based on maximum food consumption, usage, and occupancy rates identified for the site in the Land Use Census or RG 1.109.

This change is editorial and does not affect the accuracy or reliability of dose calculations or setpoint determinations.

4.2 The definition was expanded to include an explanation of e

an initial RB purge vs a continuing RB purge.

'I c

the release activity is negligible.

This change: -is editorial:nnd does not affect the accuracy or reliability-

,of dose calculations or setpoint determinations.

I, 4.6 The definition of MAXIMUM EXPOSED (HYPOTHETICAL)

INDIVIDUAL was reworded to coincide with the definition in. Technical Specification 1.21 and Regulatory Guide I

1.109.

In addition, the definition. was expanded to clarify.the difference between dose calculations for.the MEMBER OF THE. PUBLIC and the MAXIMUM EXPOSED : INDIVIDUAL..

,a,g This change is editorial and does not affect the accuracy or reliability of dose calculations or setpoint

L 4.8 The definition of UNRESTRICTED AREA was modified to stat'e that "For environmental ' protection / effluent control purposes; the Rancho.Seco Unrestricted Area is the area I

outside the Site Boundary as shown in Attachment 8.7."-

J

'This attachment is a map;of the Site Boundary used for

. liquid - and gaseous dose calculation purposes.

This change does not Laffect1the accuracy or reliability of 4

dose calculations or setpoint determinations.

t 4.9 The definition of EXCLUSION AREA was added.

This change-I is editorial and does not affect the accuracy or reliability of dose calculations or setpoint determinations.

4.10 The definition of NUISANCE PATHWAY was added to alleviate the 'needL.to track -activity. releases that do not contribute significantly(1 % for:1'iquids, 5 % for gases) i 7

to=the cumulative dcse totals.

These releases include a

l secondary steani releases and trace levels of activity in a

normally non-radioactive liquid effluents.

I Justifications ' for secondary gas Nt*ISANCE pathways is in l

section 6.1.2.

Trace levels NUISANCE pathways are J i, evaluated in CCF 89-559 & 89-569.

The definition of GRTS was added to clarify that.the WGS 4.15 and VETS are the systems installed to reduce the quantity.

of radioactive materials in gaseous effluents.

This I

change is editorial and does not affect the accuracy or reliability ~

of dose calculations or setpoint determinations.

5.0 The responsibilities section was added to comply with the formatting requirements of Rancho Seco Administrative I'

Procedures. This change is editorial and does not ' affect

theo accuracy or reliability of dose calculations or-setpoint determinations.

Section 6 was formerly Section,5

-The statement 5.9.2 which stated that

tritium, radioiodine, and-1 particulate activity dose _do not need to calculated for pre-release. purposes is implicitly implied-'by not f

1 requiring them and the rtatement is not included.

The R

general arrangement of the gaseous effluent release

.j pathways did not change.

Several potential release pathways other than those

/

idanufied in the schematic, Attachment 8.2, are 4

I

. unmonitored steam releases from secondary plant equipment discussed in this section.

These pathways are and ordinarily contribute-little to dose tdtals.

i An' analysis of the releases for the second half of 1988 K

showed that-needless time and effort-was spent on the trackingiof these releases because the doses' calculated

'l were insignificant.

To - alleviate this problem. Action'-

~

Le'rels will be established to trigger when the evaluation-o l'

of secondary plant vents / reliefs shall be evaluated. The Action ~ Levels will be based on conservative assumptions.

so that the cumulative doses due to-gaseous releases are l

not underestimated, For clarification, this section in the ODCM will not preclude -Rancho Seco personnel from the obligation to-1 control and limit unplanned ventings.

The correction of-

~

l

-equipment leakage is still a priority. Also, actual UNPLANNED : RELEASES as defined in Step 4.10 shall be 1

evaluated for the cause(s) of the release, the. action taken to prevent recurrence and the consequences of the release as required by Technical Specification 6.9.2.3.1.

3 However, most of the tracking of abnormal releases

.r.

3 1988 ' involved planned releases through plant equipmeat

E which had little ef fect on cumulative dose totals.-

For.all of the reasons above, the use of Action Levels J

does not reduce the accuracy or reliability of dose

calculations.

-1 I

BASIS FOR ACTION LEVELS In Attachment A, the abnormal gaseous celeases for-the~

second half of'1988 are listed. The curias released from the IOS and the Respirator Cleming Trailer have been I

segregated from the other releases because they are considered miscellaneous planned release pathways'in that i

they are routinely monitored.

6.2 (Formerly-step 5.2.2)

This section has been-completely I.

reorganized and restated.

See separate : ht.adings for details of specific changes.

e (Formerly step 5.2.2.1)

Revision 6. required the~ setting of the liquid ef fluent monitor setpoint based on the

" DEFAULT HISTORICAL MIX" when no release =is occurring.-

This revision will require the setpoint. to - be set as I

close to background as possible without causing spurious alarms or as determined by Chemistry Supervision.

Thisi change does not af fect the accuracy or reliability ~ of ~

I dose calculations or setpoint determinations.

6.2.1 Because the conversion factor for the effluent monitors.

I plays a major role'in the detection capabilities;of the:

monitors, a

section on the detarmination. of the.

conversion factor was added..8'was also-added listing the detection efficiencies fer-the liquid I

monitor.

This change will increar.e the reliability of setpoint calculations.

6.2.2

'(Formerly step 5. 2. 2.1.1 &

5. 2. 7. 1. 2 )

Since there is-only=one effluent monitor (R15017A), only one. equation-is applicable. Therefore, the previous'two calculations have been reduced to the one applicable calculationifor the liquid effluent monitor.

Also, since R15017A does not detect non-gamma emitting nuclides(H3),

the denominator of the equation has been modifed.to account-for this.

This change will increase the reliability of setpoV.t calculations.

I 6.3 (Formerly step 5.2.3 & 5.2.1.2)

Tnese steps have been-6.3.1 reorganized and restated to provide more clarification.

Previously, the pre-release and post-release equation E.

were separated into different steps.

Effectively, the 5-equation has stayed the same.

Implementation procedures determine how to apply the equation in different situations. This change is editorial / procedural and does I

not affect the accuracy or reliability of dose-calculations or setpoint determinations.

6.3.2 (Formerly step 5.2.1.3, 5.2.1.3.1, 5.2.1.3.2)

determining gaseous MPC' values.

Even thougn Technical specifications do not have gaseous MPC limits, reporting I

compliance of 10 CFR 20.106 and 10_CFR 50.72 must still' be done.

Therefore, th'a MPC calculation methodology was added.

This change does not affect the accuracy ~ or reliability of dese calculations or setpoint I

6.9,10 (Fotaerly 5.8, 5.8.1, 5.9, 5.9.1)

The general methodology has not changed since the last revision. The-option to.use concurrent meteorology is included because I

the Semi-Annual Report uses concurrent values.

The:

acronym EMS -was changed to REIMS(They are synonomous).

This change does not affect the accuracy or reliability I

of dose calculations or setpoint determinations.

6.11 A section on gaseous dose projections was added.

Step 5.9.2 previously was called the Pre-Release Dose.

' [L Projection section but only addressed pre-release dose E

calculation requirements.

This section is implicitly L a~ ;

defined in step 6.1.2.

This change is editorial and does not affect the accuracy or reliability of dose

- g' calculations or senpoint determinations.

6,12 (Previously 5.10, 5.10.1,2,3)

The Fuel Cycle Dose B

section has been rewritten and modified to provide-clarificatic.a and -nimplification.

In the' previous g

revision, neparate equations were used to calculate Fuel.

g cycle Dose from noble gases. The separate equations'will~

not be used in this revision.

Equations from steps 6.4, 6.9, & ~6.10 will be referenced to provide the general methodology to perrorm. dose calculations.

Also, this

,I section will. not incorporate a standard residential-shielding factor.

Requiring that-certain-exact parameters be used would not be realistic because for an I

evaluation of a REAL INDIVIDUAL's doso, the parameters will change from one case to another.

Therefore, the g

general methodology only need:s to be provided and each I

instance' woc d be done on a case by case basis.
