Top Priorities

1. Install filters in air ejector diacharg, .

Status: Double teea are installed. Duct work haa been tactvelded and welding ia proceeding. Should be complete on 4/12 and be ready for teat.

2. Ch3nge out charcoal filter• in one SO% train in Auxiliary Building.

Status: Filters on-aite. Procedure complete .and available. Trainin~ ia complete. Filter change delayed due to procedure aprroval .delay. EstiQate 3 to 4 daya to coaplete change.

, . I •

No fire hazard exists from expended charcoal. Filters will be double wrapped in poly and shipped in wooden crates.

3. Ch3nge out charcoal filters in one 50% train of nt Bldg.

Status ~ Fllt~rs are avoidable. Work scheduled to begin upon completion of AB filters.

4. Install liquid waste tank farm in spent fuel pool A.

Status: Steel for racks will be on-site on 4/12. The tanks are being modified and will be back on-site in time to be put in pool. All pipe is on-site; valves and instruments are on order. Con­crete shield slabs will be fabricated on-&ite. Will retain capability to flood pool if desired. Foreman has been assigned and ia lining up personnel. Estimated completion is 4/22 to 4/26.

5. Install Cap-Gun syst~ in Chemical Cleaning Building to process Unit 2 water.

Status: Building is being cocooned on inside and monorail to remove cask is being installed. 20-ton hoist is being flown in from Wlscon­si~ on 4/12. Eaticated completion. is 4/23 but schedule is being reviewed.

6. Decay Heat Removal System (Support of Base Plan).

Status: Upgrading of existing system being held up by AB contamination. Decontaminat!on to begin 4/13. The skid ayste= will be installed in pit outside building. May be some interference with buried pipe.

7. P/V Control Sys tem (Support of Base Plan).

Status: Crit~ria being established for N2 pressurized passive system. Schedule to bo established.

Technical Review Meeting

1800, 4/11/79

1. Sample of MO tank could not be obtained at 5 psi . Isolate tank, let pressure build up to 10 psi and attempt to get a sample.

2. Criteria has been established to get into long­term using natural circulation.

a. Provide schedule for using both "A" and "B" OTSG in a solid condition.

b. Write procedures for initiating natural circulation based on criteria.

3. B&W has looked at the Reflux method of cooling as a back- up to natural circulation. It looks promising, but tw.. ~tems require additional study.·

a . Study effects of noncondensibles.

b. Study how to m~asure water level in reactor vessel.

4. Provide results of primary sample analysis of the Bettis, ORNL, and Savannah River.

5. Determine ~~thod of getting pressurized primary sample by shielding the 250 mil bomb or modifying rig for 30 mil bomb.

6. Provide rationalization for proceeding to Point B (reduced temperatu~e) on Base Case summary Rev. 2 . To be revi ewed by NRC before proceeding.

1. Determine what documentation for SER and tech. spec. changes must be transmitted to NRC under a Met-Ed signature.

B. Prepare submittal to NRC for Long-Term Cooling using Natural Circulation.

1. Submit to NRC by 4/12 .

2. Review by 4/13.

'4/11/79 1700

(1) Degas at A. Lower pressure (A~A') while degassing, then return to A.

(2) Continue design/installation of sta"tic & active systems for primary rnakeup,'lcvcl control and secondary cooling system for S/G "B".

(3) n~duce temperatur~ (A_.B) by stea~ing on "A" S/G. Verify operability of se•ondary cooling system for "B" S/G. .

(4) At B, establish st lid cooling to "B" S/G, and when stable, isolate "A .. S/G. •

• (5) Reduce temperaturt (B~C) with S/G "B". As soon as possible, start solid operation with "A" S/G, with modification pkg to be determined.

(6) At c, trip RC Pump "A" and establish natural circulation in •A" and •a .. loops.

(7) Reduce primary pressure to value to be determined (C-•D).

(8) T"ke primary system solid - activate new MU/pressure control systel.\.

END POINT Primary: Natural circulation, solid water, long term P/V control Secondary: Solid water, long term heat dump system
