~' Page 1 of 3 i SAFETY EVALUATION This amendment application requests a revision to Technical Specifications (T/S) 3/4.3.2 and Surveillance Requirement 4.8.1.2. These specifications are revised to require the emergency diesel generator (EDG) solid-state load shedder emergency load sequel'cers (LSELS) and 4KV bus undervoltage (UV) devices be operable in plant modes 5 and 6. Proposed Change This amendment application revises T/S 3/4.3.2, Tables 3.3-3, 3.3 1, and 4.3-2 Functional Urits (8) " Loss of Power 4KV Bus" and (10) " Solid State Load Sequencer" by: 1) changing " Solid-State Load Sequencer" to " Load Shedder Emergency Load Sequencer" in Tables 3.3-3, 3.3-4, and 4.3-2, Functional Unit (10); 2) adding Mode 5 and 6 applicability for the LSELS and its supplying 4KV bus UV circuit to Tables 3.3-3 and 4.3-2, Functional Units (8) and (10); 3) adding notes to Tables 3.3-3 and 4.3-2 which explains the operability requirements of the LSELS and corresponding 4KV bus UV devices in Modes 5 & 6, and; 4) revising Table 3.3-3, Action Statement 25, which corresponds to Functional Unit (10), by adding a reference to Specification 3.8.1.2. 2 Surveillance Requirement 4.8.1.2 is revised by exempting the LOCA sequencer from the portions of Specification 4.8.1.1 which are not applicable (e.g., the LOCA sequencer is not required in Modes 5 and 6). Background and Safety Analysis The EDG solid-stated LSELS perform two basic functions, load shedding and load sequencing. The load shedding function removes selected loads from the Class 1E buses under degraded bus voltage conditions or upon the presence of a safety injection signal and scnds a starting signal to the EDG. The sequencing function actuates equipment fed from the Class 1E buses in a predetermined sequence following degraded bus voltage conditions or in the event of a loss-of-coolant accident. This ensures that the voltage and frequency of the Class 1E buses are not degraded below design parameters due to the he,vy starting currents of the actuated equipment. An inconsistency exists in T/S for the EDG solid-state LSELS which could lead to a T/S compliance problem. T/S Surveillance

H .Page12 of13-4.8;1.2, states:that the emergency diesel-generators:shall be ~ demonstratedioperable, in Modes 5 & 6, by the performance;of-Surveillance.RequirementL4.8.1.1.2.f. _This: surveillance requirement discusses the use of the shutdown /LOCAjsequencers,- which implies that the sequencers.are operable. However', T/S 1 3.3.2'(10) only requires the. load sequencersLto be operablefin-Modes 1 through'4. With the load sequencers de-energized'and_ j -inoperable in Modes 5 & 6 they are not required to be surveyed' per T/S 4.0.3 and they are'not. required-to be operable by the T/S 3.3.2 mode applicability. Per T/S 4.0.1, surveillances shall be! met in the modes specified in the LCO. Without the. load sequencers operable, surveillance 4.8.1.1.2.f cannot be met., This T/S amendment rectifies the above compliance _ concern by-imposing Mode 5 & 6 applicability for the LSELS. Requiring the LSELS to be operable in Modes 5 & 6 enhances plant operability in j the. shutdown modes and does not cause a safety concern. Previously T/S did not require the LOCA sequencer to be operable-since LOCA is not analyzed in Modes 5 & 6. The shutdown sequencers were not. required to be operable because plant operators were relied upon'to take manual action to recover from D a loss of offsite power. In addition, the Standardized Technical Specifications developed-by MERITS-(Methodically Engineered, Restructured and Improved Technical Specifications and associated Bases) support a. requirement for OPERABILITY of the sequencers in shutdown-modes. The requirements for sequencer OPERABILITY for thel OPERABLE AC source were originally stated in the draft for AC Sources-Shutdown, Modes 5 and 6.(LCO 3.8.2,_page 3.8-28). The review of. + the draft-suggested removing this section on the~ basis that " load-sequencers are integral to the diesel generator OPERABILITY, and do Iat require unique mention in the LCO". Evaluation The proposed change _to Technical Specifications does not involve an unreviewed safety question because-operation oftthe'Callaway-Plant with this change would not: 1. Increase the probability-of occurrence or the-consequences: of an accident or malfunction of equipment.important 'tua safety previously evaluated in the safetp analysis l report. There is no increase in the probability of occurrence,or the consequences of an accident. This change enhances plant-operation in shutdown modes, which adds a eafety benefit. 2. Create a possibility for an accident or malfunction ofEal different type than any previously. evaluated in.the safety analysis report. There is no new type of accident or malfunction created and the method and manner of plant operation will only change by adding OPERABILITY-requirements for LSELS.in MODES 5 & 6, which enhances 1 plant safety in! shutdown modes.

E ) e ) Page 1 of 1 ) SIGNIFICANT HAZARDS EVALUATION i This amendment applicatica requests a revision to Technical Specification 3/4.3.2 and Surveillance Requirement 4.8.1.2. These specifications are r6v:1 sed to require the solid-state load shedder emergency load sequencers (LSELS) and 4KV bus. undervoltage devices be operable in plant modes 5 and 6. The proposed change does not involve a significant hazards consideration because operation of Callaway Plant with this change would not: 1. Involve a Jignificant increase in the probability or y consequences of an accident previc:mly evaluated. The ~ Callaway-Safety Analysis Report has been reviewed,and been found to be unaffected by this proposed change. This change will not increase the probability or corsequences of any accident or malfunction of equipment because the LSELS will be required to be operable in modes 5 and 6 which enhances. plant operability. 2. Create-the possibility of a new or different kinu of accident from any previously evaluated. ' This change increases the operability requirement for th? L3ELS. .There is no new type of accident or malfunction created and the-method and manner of plant operation will only change by adding OPERABILITYfrequirements fnr LSELS in MODES 5 & 6, which enhances plant safety in shutdown-modes. 3. Involve a significant reduction in a margin of safety. The margin of safety remains unaffected since no design change is made and plant operation remains the-same. As discussed above, the: proposed change does not involve.a-significant increase in the probability or consequences of an j accident previously evaluated or create the' possibility.of a new or different kind of accident from any previous 2/ evaluated. This change does not result in a significant' reduction-in a margin of safety. Therefore,. it has been determined that the' proposed change-does not-involve a significant hazards consideration. + -.4 f l .,h n..,,oh.--,,c..,. +., ,w. ...re.- ,,e e m. a.w q,,,, i, y,,, - 2,.w. 3 m-- ,,+# y
