" broken pipes or stuck-open valves that cause water to be drained from the reactor vessel

 broken pipes or stuck-open valves that cause water to be drained from the reactor vessel However, none of these appear to explain the step.
The reactor power level had been zero since 2:47 pm, providing no opportunit­y for another large, rapid reduction.
The reactor vessel pressure plot on page 8 shows a steadily rising pressure trend, not the kind responsibl­e for downward step changes in reactor vessel water level.
There’s no data indicating a source of cold water injection around 3:04 pm. The logic, turbine speed, and flow charts for the high pressure coolant injection system indicate it did not operate during this time period. And the reactor pressure was too high for the core spray and residual heat removal systems to supply water to the reactor vessel. Thus, the emergency core cooling system pumps did not inject cold water into the reactor vessel around 3:04 pm. And as previously discussed on page 6, the closed MSIVs prevented normal makeup flow to the reactor vessel via the feedwater system.
Broken pipes, stuck-open valves, and other explanatio­ns for the level drop seem to be contradict­ed by the fairly steady trend between 3:05 pm and 3:17 pm and the increasing pressure trend over that period shown in the prior chart.

 

Consider:

A. When the Big Quake happens, piping starts to leak, slowly at first, then as the pressures starts to fluctuate, it leaks faster before the connection breaks/fai­ls and then causes a much more massive leak which dooms the reactor, because "the MSIV's (valves) prevented normal makeup flow to the reactor vessel via the feedwater system".
B. As the leak started (say around 3:04pm)the pressure tended to go down but as it did so, the level being measured continued to slowly rise because of the PV=NRT laws...
C. BTW: I cannot view the sub documentat­ion: The page you requested was too large to translate.

D. It is sad that all this data was available in May and we are "just now" able to comment on it; PLUS since TEPCO has a questionab­le history of SPINNING Data, one wonders if these records were tampered with before they were released.

Imagine a airliner crash where the Airline Owner/Oper­ators had access to the black boxes for several months BEFORE they were released to the FAA!

Update 10-14-12, SCE’s Replacement Steam Generator $680 Million Debacle

The DAB Safety Team’s - Update 10-14-12, SCE’s Replacement Steam Generator $680 Million Debacle

1. If SCE’s and MHI’s Engineers had used all the following guidelines, they would have prevented the
Replacement Steam Generators (RSG’s) catastrophic failures and they would not be in financial trouble with the SONGS Union Workers, the NRC, the Public, the News Media and their Ratepayers:

• Human Performance Tools, along with the NRC Branch Chief and World’s Foremost Expert’s sage advice of “read between the lines', ‘use critical questioning & an investigative attitude', 'solid teamwork & alignment, and ‘read the academic papers on eliminating fluid elastic instability and flow-induced vibrations in nuclear power plant components.”

• Benchmarked the design details of Palo Verde and other CE RSGs design details in order to eliminate any potential fluid elastic instability and or flow-induced vibrations experienced in the SONGS CE Original Steam Generators (OSGs), so that they would not occur in their new RSG’s.

2. SCE should have embraced rather than bypassed the FULL NRC Licensing Amendment Process.

• SCE “Sweet Talked” NRC in accepting the results of Inadequate Industry Benchmarking and the Defective 10 CFR 50.59 Evaluation and thus avoided the thorough and lengthy scrutiny of FULL NRC 10 CFR 50.90 Licensing Amendment Process.

• Note, the lack of strict oversight by Region IV NRC Staff as required by NRC Reactor Oversight Process, was a critical flaw that enabled the debacle.

What is needed to prevent the adverse consequence of a Main Steam Line Break outside Containment and the resulting nuclear radiological disaster in Southern California, if SCE’s Degraded Unit 2 is allowed to restart at 70% power for an operations trial period of 5 months as an, “Unapproved Experiment”, as SCE and 3 out of 4 Nuclear Energy Institute Qualified “US Nuclear Plant Designers” are recommending?

1. Submittal of a NRC 10 CFR 50.90 Licensing Amendment Application for SONGS Unit 2 Restart Plan by SCE.

2. A thorough review of SONGS Unit 2 Restart Plan Return to Service Report by Region IV NRC Staff, NRC Chairman and Commissioners, U.S. Senate Committee on Environment & Public Works, and independent verification/ by the NRC Offices of Nuclear Reactor Regulations, Nuclear Regulatory Research1 and the Union of Concerned Scientists.

3. Sworn testimony by all parties responsible for the preparation of SONGS Unit 2 Restart Plan Return to Service Report to insure that public safety and health will not be compromised in case of a nuclear Accident caused by a Design Bases Earthquake/Main Steam Line Break due to multiple tube leaks or ruptures or combination thereof.

4. Investigation of SONGS Safety Violations and Worker Discrimination, Retaliation, Intimidation and Harassment by an Independent Federal Commission appointed by the President or the Supreme Court of the United States. This is required to guarantee public acceptance of the results these investigations by the people of Southern California.

5. Return of the 1.2 Billion Dollars that the ratepayers have “fronted” SCE to date, with interest.

6. A Financial Bond Guarantee by Southern California Edison to cover the Financial Ruin of Southern California’s economy in case of any nuclear Incident/Accident.

1Dr. Joram Hopenfeld, a retired engineer from the Office of Nuclear Regulatory Research, sharply criticized NRC officials for downplaying the dangers of degraded steam tubes in December 1999, three months before the Indian Point accident, and said, “To be credible, risk-informed regulation mandates statistically valid and scrutable data, competent insights of accident scenarios and their consequences, and of accident prevention strategies, as well as meaningful public involvement. In reality, the staff examines accident scenarios and their consequences in a superficial manner; accident prevention is apparently dictated primarily by financial considerations, and the public is being excluded from meaningful participation in the NRC deliberation process’, ‘The nuclear industry and the NRC have a poor track record of controlling steam generator tube degradation.” The NRC's Advisory Committee on Reactor Safeguards (ACRS) issued a report in February 2001 and substantiated many of Dr. Hopenfeld's concerns.
