In accordance with a request made by Mr. A. Bournia during a telecon of January 22, 1985, the following information is provided. It is intended to supplement the Reference (c) submittal regarding an extension on the schedular requirements of 10CFR 50.49 (g). Provided as Attachment A is a table which identifies by equipment number each application for which an extension is being sought. Also identified is the manufacturer and model number of the pertinent item.' This table corresponds directly to the report provided in Reference (c) which broadly reviews the actions required to attain a qualified status and proposes a schedule for implementation. Further, in the column headed

       " Reference",'the page number is identified from the LaSalle County Assessment to Justify Interim Operation, VOL II, QUAD-1-81-852 (Rev. 3, June-1982) compiled by Quadrex Corporation, where the item was individually reviewed by function, failure mode and effects, and whether operator action was required for the needed safety function. For your convenience,. copies of the pertinent pages are provided in Attachment B.

Recall that the main volume of the report was transmitted.to ;the Commission per Reference (a) and followed-up by explanatory FEA's 'via letter of October 22, 1981; the commission's acceptance was provided in Reference (b) following the field audit of October 1981.

m) COMP 0NENT APPLICATION STATEMENT ^ Component AP-75E , C This component is located in the Reactor Building, 740' elevation in environmental zone H4A. Hence, this component is exposed to a harsh environment for the Instrument Line Break Event Outside Contain-ment and high radiation from the LOCA Inside Containment (see Section 4.4, page 4-32, of Quadrex Report QUAD-1-81-852). The impact of component failure is considered only for these events. (a) Component Function This component provides motive and control ppwer to the components shown in the references key diagram - 480 volts MCC135Y-1(Division 1). ( (b) Effect of Component Failure

The failure of this component due to the Instrument Line Break Event in the Reactor-Building or the LOCA event will not. preclude

, achieving the six _ safety objectives, namely safe shutdown, contain-ment isolation, core coverage, RHR, containment integrity and

   .C effluent control (see Section 4.4, page 4-32, of Quadrex Report QUAD-1-81-852).

Failure of this component for this event will not affect the other 480 volt components in the electrical power distribution system.-

     -                           For a break in the RCIC cubicle, the RCIC is considered unavailable. This occurs only in one of three ECCS divisions.

Therefore, two full divisions are available to mitigate the event. No operator action is required with the unavailable RCIC. Following accident confirmation based on leak detection, emergency procedures are followed for long term core and containment cooling usi.no the remaining two divisions (no action prior to 10 minutes-after the event) resulting in meeting all six safety objectives. In the analysis of LOCA and HELB, no credit is given for RCIC. Based on these facts, this component does not require hcrsh environ-mental qualification and'will be removed from the h.arsh qualification-s program. However, .tnis component will be qualified to normal and

Hence, this component is exposed to a harsh environment for the Instrunent Line Break Event Outside Containment and high radiation from the LOCA Event Inside Containment (see Section 4.4 page 4-32 of Quadrex Report QUAD-1-81-852). The impact of component failure is considered only for this event. (a) Component Function These motor operated valves are required for primary contain-ment chilled water outboard isolation. (b) Effect of Component Failure Failure of these valve operators in the worst condition will prevent these valves to close upon receiving an isolation signal from the primary containment and reactor vessel isolation system. Containment isolation is achieved by automatically closing inboard isolation valves S which are located inside the containment, therefore, they are not affected by the instrument line break. In addition, this is a closed system within primary containment.- The failure of these components will not preclude achieving the six safety objectives, namely safe shutdown, containment r isolation, core coverage, RHR, containment integrity and CU effluent control (see Quadrwx Report QUAD-1-81-852). No failure mechanism at the valve can cause the valve to change position from open or close because the motor control ' L centers are not at the same location as the valves.-

Hence, this component is exposed to a harsh environment for the Instrument Line Break Outside Containment and high radiation from the LOCA Inside Containment (see Section 4.4, page 4-32, of Quadrex Report QUAD-1-81-852) . The impact of component failure is considered only for these events. (a) Component Function This component provides minimum flow bypass to suppression pool. (b) Effect of Component Failure Failure of this component prevents minimum flow to the suppression pool. This valve is not required for safe shutdown or core coverage functions. Failure of this component has no effect in achieving the six safety objectives as described in Quadrex Report 3 ' QUAD-1-81-852. No failure rechanism at the valve can cause the

                                   . valve'to change position from open or close because the motor control centers are not at the same location as the valves.

(c) Impact on Other. Systems . No other components or systems are affected by the failure of U (L'- this component. :This valve has no electrical interface with

lather components of this system _or. any other system.

I' (d) Operator Action j c) This device is not required when the harsh environment caused. by the Instrument Line Break and LOCA exits. Therefore, no operator action is required to achieve any of the six_ safety objectives.

4 Component Application Statement (MSIV Position Switches) Component: MSIV Position Switches on Main Steam Isolation Valves (IB21-F022A,B,C,D; IB21-F028A,B,C,D) The limit switches on these valves track MSIV position. Actuation of the MSIV's is not dependent on these switches, nor does failure of these limit switches affect MSIV operation. . These limit switches provide a valve closed signal to the Reactor Protection-System logic. This logic provides a scram signal to anticipate the pressure / flux transients associated with MSIV closure. This trip signal is an output of

          ,the reactor protection system.                                                                                                                                              l Position switches mounted on the inboard MSIV's (F022A-D) are in environmental                                                                     *

e Component Application Statement (MSIV Position Switches) (Cont'd) (c). Operator-Action Due to physical separation of the inboard and outboard switches, the scram signal can be provided by the group unaffected by the steam / moisture associated with the DBE. Additionally, other instruments monitoring other vessel parameters (pressure and flux) are also available

                      . to initiate the scram signal. No operator action is required to meet the six safety objectives.

( m) COMP 0"ENT APPLICATION STATEMENT Component B21-t;039A, 3, C, D, E, F, G, H, J, K, L, M, N, P, R, 5, U, V { These Barksdale BIT-M12SS-GE reactor pressure components are located - l in the reactor building in environmental zone H4A. Hence, these com-  ; ponents are exposed to a harsh environment only for the Instrument Line Break Event and high radietion from the LOCA inside containment (see Section 4.4, page 4-32, of Quadrex Report QUAD-1-81-852). The impact of component failure is considered only for these events. (a) Component Function These components which are located in Division I of the Auto Depressurization System are used to sense reactor pressure and will initiate the safety / relief valve (NO39A, B, F, G, H, J, K, L, M, N, & P) and ADS valve (NO39C, D, E, R, S, U, & V) function for vessel depressurization. (b) Effect of Component Failure The failure of these components will not preclude achieving the six safety objectives, namely safe shutdown, containment isolation, core coverage, RHR, containment integrity and effluent control (see Section 4.4, page 4-32, of-Quadrex Report QUAD-1-81-852). Failure of these components will affect the operation of a given

                       ,                   ADS or SR valve, and disable the Lcw-Low set arming function.

(c) Impact on Other Systems

         '                                 The sole function of these components is to initiate opening of an
                    '                      ADS or SR valve and arming of the Low-Low set function. No other j                                 systems are affected by their failure.

6 i (d) Operator Action The safety / relief valve system is not required for these events which are depressurization events. Division II of ADS is available l as well as HPCS if necessary. No operator action is required to i meet the six safety objectives. , ,.<- I
