7590-01 UNITED STATES NUCLEAR REGULATORY COMMISSION 1
CONNECTICUT YANKEE ATOMIC POWER COMPANY j
DOCKET NO. 50-213 i
j NOTICE OF CONSIDERATION OF ISSUANCE OF AMENDMENT TO FACILITY OPERATING LICENSE AND PROPOSED NO SIGNIFICANT HAZARDS i
CONSIDERATION DETERMINATION AND OPPORTUNITY FOR HEARING The U.S. Nuclear Regulatory Commission (the Commission) is considering issuance of an amendment to Facility Operating License No. OPR-61 issued to Connecticut Yankee Atomic Power Company (CYAPCO, the licensee) for operation of the Haddam Neck Plant located in Middlesex County, Connecticut.
The proposeo amendment would reword Technical Specifications (TS) Section 3.4.6.2.f to better define which sections of piping need to be included under surveillance 4.4.6.2.1.g.
Surveillance requirement 4.4.6.2.1.g has been changed to remove the surveillance requirement for portions of the high pressure injection safety injection (HPSI) system, charging and residual heat removal (RHR) suction piping.
In addition, TS 4.0.4 has been determined to be not applicable for entry into MODE 4 for this surveillance requirement.
As a clarification, the note at the end of surveillance requirement 4.4.6.2.1.h has been modified to explicitly state that it is only applicable to surveillance item "h."
The Bases section for " Low Temperature Overpressurization Protection Systems" would be changed to describe the for requirement to lock out one centrifugal charging pump and both HPSI pumps in MODES 4, 5, and 6 with the l
reactor vessel head installed.
Before issuance of the proposed license amendment, the Commission will have made findings required by the Atomic Energy Act of 1954, as amended (the G
Act) and the Commission's regulations.

- The Comission has made a proposed determination that the request for amendment involves no significant hazards consideration.
Under the Comission's regulations in 10 CFR 50.92, this means that operation of the facility in accordance with the proposed amendment would not (1) involve a significant l
increase in the probability or consequences of an accident previously evaluated; or (2) create the possibility of a new or different kind of accident from any accident previously evaluated; or (3) involve a significant reduction in a margin of safety.
In accordance with 10 CFR 50.92, CYAPC0 has reviewed the proposed Technical Specification and concluded that they do not involve a significant hazards consideration because the changes would not:
1.
Involve a significant increase in the probability or consequences of an accident previously analyzed.
The proposed change to Section 3.4.6.2.f is a rewording of the specification to better define which sections of piping need to be included under Surveillance 4.4.6.2.1.g.
The proposed changes would remove the requirement to perform a monthly pressure test on portions of HPSI, Charging and RHR suction piping which would be used for or pressurized during containment recirculation.
Performance of this test during normal operation for certain sections of piping, is either not possible due to physical or operational constraints (Charging and RHR suctionpiping)orwouldrequiretheremovalofbothtrainsofsafety
3 related equipment from service during testing (HPSI suction piping). The propcsed change would be in keeping with safety and the desire to maintain high ECCS availability. These sections of piping will be tested pursuant to Technical Specification 4.0.5 and the Haddam Neck Inservice Test (IST) program.
In addition, Technical Specifications require that this piping be monitored for leakage at least once per twelve hours, and provides assurance that there is no gross leakage associated with this piping between pressure tests. Therefore, there are no failure modes associated with the proposed change nor any design basis accidents impacted by the change.
The change to Section 4.4.6.2.1.g also permits entry into MODE 4 prior to performing the leakage surveillance.
Specification 4.0.4 requires that all applicable surveillances be performed prior to entry into the plant mode for which an LCO is applicable (i.e., in this case, MODE 4). Howt'er, Specification 3.5.2.a requires that both HPSI pumps be inoperable whenever LTOP is required (Mode 4 with RCS temperature less than or equal to 315'F and Modes 5 or 6 with the RCS not vented, per Specification 3.4.9.3).
Because of these conflicting requirements, the plant would be required to be placed in Mode 5 with the RCS vented to perfor*A the HPSI discharge
i
~4-piping. leakage surveillance prior to startup from a shutdown (Modes 4, 5, or 6) if Surveillance 4.4.6.2.1.g has not been performed in the previous 31 days.
This change provides a window at the upper end of Mode 4 (RCS temperature between 315 and 350'F) to perform HPSI discharge piping leakage testing.
There are no technical specification requirements for HPSI pump operability or inoperability while operating in this temperature band.
The note at the end of Surveillance 4.4.6.2.1.h, which permits transitions into Modes 3 and 4 prior to completion of surveillances, has also been modified to state that this note applies to item h only and not the entire specification.
The applicability of this note has resulted in some confusion. This change has no negative safety significance since it is editorial and eliminates the potential misapplication of a specification.
The change to Section 3/4.4.9--Low Temperature Overpressurization Protection System Bases has no safety impact since it is'being made to be consistent with Technical Specification 3.5.2.a which requires that one centrifugal charging and no HPSI pumps shall be operable whenever the LTOP system is required.
l l
For these reasons, the proposed changes do not increase the probability or consequences of any accident previously analyzed.
l l

2.
Create the possibility cf a new or dif ferent kind of accident from that previously analyzed.
The rewording of Section 3.4.6.2.f allows it to be consistent with surveillance 4.4.6.2.1.g by better defining the portions of piping tested.
The exception to Spc:ification 4.0.4 in surveillance 4.4.6.2,1.g alleviates a conflict with specification 3.5.2.a.
The change to the note in surveillance 4.4.6.2.1.h clarifies that the note i
only pertains to item h.
This will mitigate the confusion over application of the exception.
The requirement to lock out one centrifugal charging pump and both HPSI pumps is being made for the purpose of making the discussion in Bases l
3/4.4.9 consistent with Technical Specification 3.5.2.
There are no changes in the way the plant is operated or in the operation of equipment credited in the design basis accidents.
Therefore, the potential for an unanalyzed accident is not created.
l-3.
Involve a significant reduction in the margin of safety.
l The intent of the Technical Specifications for all changes remains unchanged.
The change to Section 4.4.6.2.1.g prevents the removal of portions of the ECCS during plant operation.
This proposed change
^
6-i maintains high ECCS availability.
The change to Specification 4.4.6.2.1.g and permits entry into MODE 4 prior to performing the leakage surveillance.
This prevents the plant from going to MODE 5 to perform the surveillance.
The changes to the Bases are editorial in nature.
The proposed changes will not impact any protective boundary and do not affect the consequences of any accident previously l
analyzed.
Therefore, there is no reduction in the margin of safety.
Therefore, based on the above considerations, the Commission has made a proposed determination that the amendment request involves no significant hazards consideration.
The Commission is seeking public comments on this proposed determination.
Any comments received within 30 days after the date of publication of this notice will be considered in making any final determination.
The Commission will not normally make a final determination unless it receives a request for a hearing.
Written comments may be submitted by mail to the Regulatory Publications l

Gelman Building, 2120 L Street, N.W., Washington, D.C.
The filing of requests i
-for hearing and petitions for leave to intervene is discussed below.
L
7 By september 12, 1990, the licensee may file a request for a hearing with respect to issuance of the amendment to the subject facility operating license and any person whose interest may be affected by this proceeding and who wishes to participate as a party in the proceeding must file a written petition for leave to intervene.
Request for a hearing and petitions for leave to intervene shall be filed in accordance with the Commission's " Rules of Practice for Domestic Licensing Proceedings" in 10 CFR Part 2.
Interested persons should consult a current copy of 10 CFR 2.714 which is available at l
the Commission's Public Document Room, the Gelman Building, 2120 L Street, N.W.. Washington, D.C. 20555 and at tLe Local Public Document Room located at the Russell Library,123 Broad Street, Middletown, Connecticut 06457.
If a request for a hearing or petition for leave to intervene is filed by the above date, the Commission or an Atomic Safety and Licensing Board, designated by the Commission or by the Chairman of the Atomic Safety and Licensing Board Panel, will rule on the request and/or petition and the Secretary or the designated Atomic Safety and Licensing Board will issue a notice of hearing or an appropriate order.
As required by 10 CFR 52.714, a petition for leave to intervene shall set forth with particularity the interest of the petitioner in the proceeding, and how that interest may be affected by the results of the proceeding.
The petition should specifically explain the reasons why intt*vention should be i
permitted with particular reference to the following factors:
(1) the nature of the petitioner's right under the Act to be made party to the proceeding; (2) the nature and extent of the petitioner's property, finarcial, or other i
L
l a
.g.
interest in the proceeding; and (3) the possible effect of any order which may be entered in the proceeding on the petitioner's interest.
The petition should also identify the specific aspect (s) of the subject matter cf the proceeding as to which petitioner wishes to intervene.
Any person who has filed a petiv. ion for leave to intervene or who has been admitted as a party i
may amend the petition without re aesting leave of the Board up to fifteen (15) days prior to the first prehearing conference scheduled in the proceeding, but such an amended petition must satisfy the specificity requirements i
described above.
Not later than fifteen (15) aAys prior to the first prehearing conference scheduled in the proceeding, a petitioner shall file a supplement to the petition to intervene which must include a list of the contentions which are sought to be litigated in the matter.
Each contention must consist of a specific statement or the issue of law or fact to be raised or controverted.
In addition, the petitioner shall provide a brief explanation of the bases of the contention and a concise statement of the alleged facts or expert opinion which support the contention and on which the petitioner intends to rely in proving the contention at the hearing.
The petitioner must also provide references to those specifiu sources and documents of which the petitioner is aware and on which the petitioner intends to rely to establish those facts or expert opinion.
Petitioner must provide sufficient information to show that a genuine dispute exists with the applicant on a material issue of law or fact.
Contentions shall be limited to matters within the scope of the amendment under consideration.
The contention must be one which, i/ proven, would d
9 entitle the petitioner to relief.
A petitioner who fails to file such a supplement which satisfies these requirements with respect to at least one contention will not be permitted to participate as-a party.
Those permitted to intervene become parties to tiie proceeding, subject to any limitat e. in the order granting leave to intervene, and have the opportunity to participate fully in the conduct of the hearing, including the opportunity to present evidence and cross-examine witnesses.
If a hearing is requested, the Commission will make a final determination on the issue of no significant hazards consideration.
The final determination, will serve to decide when the hearing is held.
If the final determination is that the request for amendment involves no significant eazards consideration, the Commission may issue the amendment and make it effective, notwithstanding the request for a hearing.
Any hearing held would take place after issuance of the amendment.
If a final determination is that the amendment involves a significant hazards' consideration, any_ hearing held would take place before the issuance of any amendment.
Nomally, the Commission will not issue the amendment until the expiration of the 30-day notice period.
However, should circumstances change during the notice period such that failure to act in a timely way would result, for example, in derating or shutdown of.the facility, the Commission may issue the license amendment before the expiration of the 30-day notice period, provided that its final determination'is that the amendment involves no significant hazards consideration.
The final determination will consider all public and State l
I l
10 comments received.
Should the Commission.take this action, it will publish a-notice of issuance and provide for opportunity for a hearing after issuance.
The Commission expects that the need to take this action will occur very infrequently.
