E. D I S*;U S S I O N Tnis crocedure assumes the ruoture of a Reactor connectec systen and a resultant loss of Reactor Coolant. It is furtner assumed tnat tne leak occurs inside tne Dry-ell and may De eitner steam or eater. The operator must use all available information to icentify tne source ana locatio1 of tne l eak. The tencerature and oressure transients resulting from tnis accicent maintain claccing integrity. Tnus, activity r el ea s ed to tne Orywell is a result of intrinsic coola7t activity ano activity r el easeo as a co7 sequence of Reactor scram and depressurization.
Suosequent to tne LOCA, fission proouct cecay heat will result in a continuing energy dump to tne Suppression Pool. Jnless this energy is removed from tne Containment, it will result in unnacceptable Suporession Pool Temperature. After ten (10) ninutes an RHR Heat Excnanger must ce acti vatea wi tn cool ing water flow.
Due to the uninerted 3r ywell , special attantion must ce g i ven to . noni tor i ng Contai nme nt Hydrogen Concentration to arevent exceecing a four (4) percent volume j concentration.
' As a fi7al last resort metnoa of acaing water to tne ,
reactor, cacaoility exists to aco laxe water to the i Reactor via 8 RHR Injection Line.

Since astomatic protective action coes not occar i nmec i a te l y , the cecision mast ce maae to continua ooeracian, olace the ol ant in a more reliaole moce or to perform a plant saatco-n and coolcoon. Variaoles tnat mJst ce consicere] inclace tne assu.nption tnat a leak cue to a small crack can aropagate into a Fast Leak, 35 well as tne raciological consequences of the escaae of Ene Coolant.
Due to tne various leak aetection systems associatec nith Reactor connectec systems. Isolation of tnese systens may o:CJr as an automatic action. Thus, the operator must cetermine the effect on plant operation of tne loss of tne isolatec systen.
Any lea < insice tne Prinary Containnent tnat cannot ce treatec as a Slow Lea 4 nust De treated operationally as a Fast Leak.

E. Ol}CU}ON Loss of the System Auxiliary Transformer with simultaneous
. loss of the Main Generator or a loss of all grid connections will cause a Loss of Auxiliary Electric Power.' Initial
, automatic action'is initiated by any combination of the following events: Turbine Generator Load Rejection, Loss of Condenser Vacuum and the Undervoltage trip of Reactor Protection-Motor Generator Sets.
1 LGA-12 d Revision 0 Marcn 21, 1979 9 (final) s' Action is directed toward ensuring that a Reactor Scram occurs, Auxiliary Power is transferred to tne Diesel Generators, and that Reactor Pressure and Water Level remain under control. In addition, ensuring continuous oil flow to the Main Turbine and Reactor Feedpumps is included to prevent equipment damage. d The Steam Condensing Mode of RHR will be used to control Reactor Pressure and Water Level due to the loss of the
, Main Condenser.
J Subsequent action is directed toward restoring power via the 4160 Volt and 6900 Volt distribution systems to reset
; the Isolation, depressurize the Drywell, reset the Scram, and minimize temperature stratification in the Reactor.

- c. If the plant is not contaninated and the Resctor is not isolated, a normal snutcown and coolcoun

- c. CAUTION must ce taken that tne unoorated water in the AHR Snatoo n Cooling lines coes not temporarily cilute the coron in tne core to allow criticality as follows:

-1) ESTA3LISS an excess doron Concentr3 tion to accomodate for tne effect of RnR dilution

- 2) STARTUP the Reactor Recirculation Pumps in SLOW spee3 in orcer to nomogenize vessel'

- c. Do not exceea a 130 F/hr cooldown rate (TS).
- e. Wnen fl ooding ne Reactor vessel up to tne steam come, use a source af -oter Dorateo to tne same concentration as tne -ater in tne
, Reactor to arevent Reactor doron concentration ailution. The SELC Solution Tank can ce ased.
However. if using tne 53LC Pumps, Reactor floccing will reqaire one to two days. An alternate pumo can ce used.
- f. Concentratian l evel s of Baron in the Reactor Vessel will oe 750-1000 pom. Tne minimum soluDility of Soron in water at 32 F is greater tnan 5C00 pam.
- g. If a fuel element failure is suspected, refer to LGA-16, Fuel E l e me nt Failure.
E. DISCUSSION An AT45 (Anticipatec Transient without scran) is extremely unlikely 3ut will require pronpt operator action to mitigate the consequences. Goerator concerns are as follows: 1) VERIFY that Recirculation pumps trio, 2) Snutdow, of Reactor. 3) Li ni t Reactor peak pressure 4) Maintain the core coverec, 5) Limit the tenperature or tne Suppression Cnameer, ana 3) Long-tern cooloo.n. Tne caerator must attemat to scram the Reactor with tne most readily availaole neans. Jpon recognizing tnat the Reactor does not scran, tne operator snould INITIATE STANO3Y LIQJID CCMT.ROL LS R L C1 W I T H I'J Tn0 MINUTE 5 0F THE EVENT to vi ni.ni ze Reactor p3.er production, wnich oaulc heat-up tne containment. HACS or RCIC operation is necessary to maintain tne core covered if' feed flow is stooped,.and should be initiated if Level 2 (-50 inches) is approachec. Suppression Pool Cooling using two RH4 , Heat Exchangers must ce initiatea to ensure tnat Suppression Cnamoer temoerature limits are not exceeded. Subsequently, tne operator nust insert enough negative reactivity into tne Reactor so tnat an uncontrolled restart will not occur. Thus, a cooldown must not ae initiatea until Control Rocs are insertec or Scron concentration is determined sati s f actor y. The consecaences 9 -
