Grimes, Director Integrated Safety Assessment Project Directorate Division of PWR Licensing - B U. S. Nuclear Regulatory Commission Washington, D. C. 20555 Gentlemen:

Millstone Nuclear Power Station, Unit No.1 Proposed Revision to Technical Specifications Condensate Demineralizers Pursuant to 10CFR50.90, Northeast Nuclear Energy Company (NNECO) hereby proposes to amend its Operating License, DPR-21, by incorporating the attached proposed changes into the Millstone Unit No.1 Technical Specifications.

The proposed revision is provided as Attachment 1. The proposed wording changes provide the option of resin rep 9 cement for the condensate deminerar zers in addition to the cerent practke of resin regeneration. Section 3/4.6.5.1 specifies limits and sampling frequenq Nr condensate demineralizer resir) to ensure that sufficient reserve capacity exists in the event of a significant condenser tube leak. This section is unchanged except to clarify that it applies to resin replacement, as well as regeneration. Section 3/4.6.3.1, which requires resin replacement when regeneration is no longer effective, has been clarified to apply to regenerated resin only. A new section 3/4.6.3.3 has been added specifically to designate the salt-splitting capacity replacement resin. It complies with the guidance in Regulatory Guide 1.56, Revision 1 " Maintenance of Water Purity in BWR's".

NNECO has reviewed the attached proposed change pursuant to 10CFR50.59 and has determined that it does not constitute an unreviewed safety question.

Specifically, the margins of safety as defined in the Technical Specifications Q

crum Bases are maintained. In addition, the probability of occurrence or the consequences of a previously analyzed accident have not been increased and the C8' possibility for a new type of accident not previously evaluated has not been

@@ created. The proposed revision does not change the minimum reserve chloride mo gx J

ion capacity of the condensate demineralizers. The function of these resins, namely to provide chloride protection, is not degraded because fresh resin provides equivalent,if not better, chloride protection than regenerated resin.

[g sI oo '

@ NNECO has reviewed the proposed revision in accordance with 10CFR50.92, and b

40 has concluded that it does not involve a significant hazards consideration. The basis for this conclusion is that the criteria of 10CFR50.92(c) are not g

• compromised, a conclusion which is supported by our determinations made

_2 pursuant to 10CFR50.59. The proposed change is not precisely enveloped by any of the examples in 48FR14870 of amendments that are considered not likely to involve a significant hazards consideration. However, the change does not involve a significant hazards consideration in light of the following:

1. The probability of occurrence of malfunction of equipment important to safety previously evaluated in the SAR is not increased because the minimum reserve chlori <le ion capacity of the condensate demineralizer is unchanged.

2. The possibility for a new type of accident not previously evaluated has not been created. Fresh resir provides equivalent or better chloride protection than regenerated resin.

3. The margin of safety as c l.oed in the basis for any technical specification is unchanged since the minimum reserve chloride ion capacity of the condensate demineralizer is unchanged.

The alternative proposed by this change is equivalent or superior to that allowed by the current Technical Specifications in every respect.

The Millstone Unit No.1 Nuclear Review Board has reviewed and approved the attached proposed changes, and has concurred with the above determinations.

In accordance with 10CFR50.91(b), NNECO is providing the State of Connecticut with a copy of this proposed amendment.

Pursuant to 10CFR170.12(c), enclosed with this amendment request is the application fee of $150.00.

We trust you find this information satisfactory.

Very truly yours, NORTHEAST 14UCLEAR ENERGY COMPANY
