With the structural integrity of the containment not conforming to the above reguirements, restore the structural integrity to within the limits prior to increasing the Reactor Coolant System temperature above 200*F.
SURVEILLANCE REQUIREMENTS 4.6.1.6.1 Liner Plate and Concrete The structural integrity of the containment liner plate and concrete shall be determined during the shutdown for each Type A containment leakage rate test (reference Specification 4.6.1.2) by:
a.
a visual inspection of the accessible surf aces and verifying no apparent changes in appearance or other abnormal degradation.

a visual inspection of accessible containment liner test channels prior to each Type A containment leakage rate test. Any contain-ment liner test channel which is found to be damaged to the extent that channel integrity is impaired or which is discovered with a vent plug removed, shall be removed and a protective coating shall be applied to the liner in that area.
c.
a visual inspectica of the dome area prior to each Type A contain-ment leakage rate test to insure the integrity of the protective coating. If a loss of integrity of the protective coating is observed, any vent plug to a test channel which may be in the area where the protective coating has failed shall be seal welded and l
then the protective coating shall be repaired.
4.6.1.6.2 Reports An initial report of any abnormal degradation of the containment structure detected during the above required tests and inspections shall be made within 10 days af ter completion of the surveil-lance requirements of this specification, and the detailed report shall l

BEAVER VALLEY - UNIT 1 3/4 6-Sa PROPOSED WORDING
ATTACHMEllT B Safety Evaluation Proposed Change Request tio. 86 amends the Beaver Valley Power Station, Unit fio.1 Technical Specifications, Appenaix A concerning various administrative changes.
Descriotion and Purpose of Change 1
Section 3.2.6 - Axial Power Distribution, is being deleted in accordance with the NRC Safety Evaluation enclosed with Tech-nical Specification Amendment No. 9.
2.
Tables 3.3-1 and 3.3-3 have been revised to identify conditions under which operating bypasses will block the Reactor Trip System Instrumentation and Engineered Safety Feature actuation channe?s.
The pennissive descriptions have also been revised to conform to the Updated Final Safety Analysis Report (UFSAR) format.
3.
Section 3.8.2.1 - (insite Power Distribution Systems, has been revised tg require the 4160 volt energency bus and applicable 480 volt emergency bus to be operable.
4.
Section 3.6.1.1 - Containment Systems, has been revised to cor-rect a typographical error.
5.
The offsite organization, Figure 6.2-1, has been revised to update the title from Director to Superintendent, Personnel Administration and to incorporate the organization under the Manager, fluclear Engineering.
6.
Section 3.6.1.3 - Containment Air Locks, has been amended by revising the Action and Surveillance Requirements. The change te the Action statement consists of a provision to allow continued plant operation with one air lock door inoperable, provided that the operable air lock door is locked closed and verified to be locked closed at least once per 31 days. The locking of an air lock -ill be achieved by: disconnecting the power source of the D.C. motor driven pump unit which supplies the hydraulically operated latches on the personnel air lock doors, and by physically locking the emergency egress air lock doors (with lock and key to the outside door and a physical constraint to the inside door.)
The surveillance requirements have been revised to require essentially what is stated in the " Periodic Retest Schedule" of 10 CFR 50 Appendix J, Section III.D.2.
Also included is a change to require conducting overall air lock leakage tests when maintenance has been performed on that air lock.
Attachment B Safety Evaluation Page 2 Basis 1.
Is the probability of an occurrence or the consequence of an accident or malfunction of equipment important to safety as previously evaluated i: the UFSAR increased? M Reason:
The deletion of Section 3.2.6-Axisl Power Distribution is an administrative change and is consistent with the NRC Safety Evaluation enclosed with Techr.ical Speci-fication Amendment No. 9.
This change is not e safety concern, since it was only applica:;1e to Cycle 1 oper-ation.
The alteration of Table 3.3-1, Reactor Trip System In-strumentation and Table 3.3-3, Engineered Safety Feature Actuation System Instrumentation is administrative in nature and does not physically change plant safety related systems, components or structures. This change is being made in order to identify conditions under which operating bypasses will block the reactor trip or eng-ineered safety feature actuation channels and will not affect the function of any equipment or systems important to safety as addressed in the UFSAR Section 7.2, Reactor Trip System or Sectior 7.3, Engineered Safety Featurcs System.
The change to Section 3.8.2.1 - Onsite Power Dis-tribution Systems is administrative and will not affect any equipment or system as discussed in UFSAR Section 8.4, Station Service Systems or Section 8.5, En:ergency Power System. The change to Section 3.6.1.6 - Containment Structural Integrity, is being made to correct a typo-graphical error. The present specification references a non-existent section 4.6.1.7.
This change is admin-istrative and will not affact any equipment or system discussed in UFSAR Section 5.2, Containment Structure.
Figure 6.2-1, Offsite Organization, hss been revised to reflect reorganization changes. This change is not a safety concern and does not affect the UFSAR.
The prcposed changes made to Section 3.S.1.3 - Containment Air Locks, are administrative changes and do not involve any physical changes to the air locks or other p. ant equip-ment, nor do they degrade the leak tightness of the air lccks. The change to the Surveillance Requfrements remains essentially the same as 10 CFR 50 Appendix J Section III.D.2, periodic retest schedule of Type B test requirements.
For these reasons, the probability of an occurrence or the consequence of an accident or malfunction of equipment important to safety as previously evaluated in the UFSAR Sections 5.2.2.5.5, 5.2.4.8 and 5.6 is not increased.

Is the probability for an accident or malfunction of a different type than previously evaluated in the Final Safety Analysis Report created? fpq Reason:
The proposed changes are administrative in nature and do not physically change the plant safety related systems, components or structures, therefore, the changes will not create the possibility for a new type of accident or malfunction of a different type than any previously evaluated in the UFSAR sections addressed above or the accident analysis of Section 14, 3.
Is the r.argin of safety as defined in the basis for any Technical Specification reduced? !!o.
Reason:
The Technical Specification BASES for the sections addressed above will not be affected by the proposed changes, as none of the systems or components will be physically changed or their function eitered in any way. Therefore, the margin of safety inherent in the applicable bases will not be reduced.
4.
Based on the above, is an unreviewed safety question involved? !!q Conclusion The proposed changes are administrative in nature end do not involve physical change to plant 3afety related systems, components or structures, will not increase the likelihood of a malfunction of safety related equipment, increase the consequences of an accident previously analyzed, nor create the possibility of a malfunction different than previously evaluated in the UFSAR. Therefore, it is concluded that, l
since the change does not involve an unreviewed safety question in accor-dance with 10 CFR 50.59, the proposed changes do not constitute a sig-i nificant hazards consideration. We have determined that this change will l
not authorize a significant change in the types or a significant increase l
in the amounts of effluents or in the authorized power level and will not result in any significant environmental impact. Therefore, pursuant to 10 'CFR 50.5(d)(4), no environmental impact statement, negative declar-ation or envircnmental impact appraisal is required.
The OSC and ORC have reviewed the proposed changes, and based on the above safety evaluation, it is concluded there is reasonable assur-ance that the public health and safety will not be endangered by opera-tions in the proposed manner.
