NRC Letter, Grimes to All Power Reactor Licensees, dated January 18, 1979.
Gentlemen:
As required by Reference 1, we are submitting an application to amend Provisional Operating License No. DPR-45 by proposing changes to Technical Specifications for the La Crosse Boiling Water Reactor (LACBWR).
The proposed changes deal with the n.cnitoring and limit-ing of effluent discharges and the supplemental monitoring of plant environs.
The proposed changes are shown as attached.
All reterences in the attached proposed changes to specifications in Section 6.0 refer to applicable sections in BWR Standardized Tech-nical Specifications.
A proposed change to LACBWR, Technical Specifications dealing with Section 6.0 items (Administrative Controls) will be forwarded at a later date.
Figure 5.1-1 will be included with that submittal.
As required by Reference 2, a drdft of the Off-Site Jose Calculation Manual (OD CM) is included with this submittal, As noted in reference 3, additional items are re-quired in the JDCM.
Those items and additional procedural require-ments will be inserted in revisions of the ODCM under current con-sideration.
References to ODCM procedures, which occur in the tables in the enclosed Technical Specification changes, will be entered upon completion of the ODCM revision. provides the rationah for the tignificant variance between our proposed and BWR Standardized Technical Specificati n with regard to liquid effluent treatment.

l ENCLOSURE 2
Reference:
Proposed Technical Specification 3.11.1.3 The liquid waste treatment system was designed to meet 10 CFR 20 limits.
Being of early design, the liquid waste system does not incorporate the latest advances in design technology.
The evap-orator and ion exchanger are the two major processing components in the system.
The evaporator has a design capacity of 1 gpm and is not functional at the present time.
The evaporator was used initially for sample runs early in the plant's history.
It was concluded that the evaporator would not be able to handle routine volumes efficiently.
The volume of water generated due to the operation of the evaporator exceeded the volume reduction achievable with the evaporator.
The evaporator has never been used at LACBWR for the treatment of liquid wastes.
i The ion exchanger is used to process tanks in order to reduce their j
activity levels to below 10 CFR 20 limits based on conservative l
dilution values.
This processing is required for less than 10% of all batch releases.
The unit has a design flowrate of 20 gpm.
Ex-perience has shown that at flowrates approaching the design values, the decontamination factor (DF) approaches one.
Thus, to achieve higher DF's lower flowrates are used.
Historically, these flow-rates have been maintained at 1-5 gpm in order to achieve an acceptable DF.
The ion exchanger can process a small number of batches on an occasional basis but is not capable of processing every batch discharge.
This is not necessary in order to meet 10 CFR 20 limits.
The above information and actual discharge data provide the basis for proposal specification 3.11.1.3.
