Samples of SCP-118 can be stored using standard containment 
procedures for non-virulent anomalous microbes. 


Description: SCP-118 is a species of ocean-dwelling protista that is 
capable of assembling functional, self initiating, nuclear devices from 
materials present in ocean water. While SCP-118 is unknown and 
hence has not been classified by the scientific community, 
specimens resemble protists of the phylum Euglenophyta but have 
significantly increased levels of movement speed, nutrient storage 
capability and resistance to alpha radiation. Specimens of SCP-118 
have been found in all of the world's oceans and seas. 


When in a survivable salt water environment, specimens of 
SCP-118 will seek out materials including but not limited to iron, 
silver, copper, carbon, TNT, and uranium isotopes. When SCP-118 


has located a material of interest the material is absorbed into the 
cell using a method dependent on the size of the material. Single 
atoms and molecules (mostly substances that are dissolved in the 
water) are passed through the cellular membrane through 
specialized protein pumps. Larger particles smaller than the cell 
itself are ingested through phagocytosis. Larger pieces will have 
particles torn off through an unknown mechanism, which are then 
absorbed using the first two methods. This "mining" occurs even in 
solid and hard substances, such as metal ingots. 


Upon reaching a threshold of absorbed materials, specimens of 
SCP-118 will move towards an "assembly area" on the bottom of the 
body of the water they are present in and will contribute to the 
assembly of a nuclear device. The nuclear devices assembled are 
gun-type fission devices using Uranium-235 as their fissile material. 
Observation of devices in the process of being assembled show that 
the process starts with the assembly of a metallic rounded cylindrical 
casing for the device, followed by the creation of two sub-critical 
masses of uranium and the conventional explosives to propel them 
into each other. The mechanism by which SCP-118 enriches 
harvested uranium is currently unknown. (See Addendum 4). The 
device is then finished with the assembly of a Uranium-238 tamper 
where the two uranium masses will collide and the assembly of a 
trigger mechanism. SCP-118 appears to assemble the necessary 
components by adding minuscule amounts of material to an (initially) 
tiny material "seed". Differing atoms and molecules can be added to 
the same component and assembled components are not 
necessarily homogeneous. It is currently unknown whether SCP-118 
builds on the seed atom by atom or by adding very small sub- 
micrometer fragments. The mechanism by which SCP-118 attaches 
new material to the seed seamlessly is unknown. The assembly time 
depends on the size of the device being assembled, water 
conditions and mineral availability but observations suggest that 300 
days for a medium size device can be considered average. 


Once a nuclear device is finished SCP-118 will detonate the device 
by completing a circuit in the trigger mechanism. Around 90% of the 
nuclear explosions recorded as a result of SCP-118 have had yields 
in the 20 to 35 kiloton range, although yields as low as 4 kilotons 
andupto _ kilotons have been reported. Aside from cases involving 


human interference, failure to detonate has never been observed, as 
all nuclear devices recorded have either been detonated of their own 
accord or removed from the water prior to completion. Devices 
constructed by SCP-118 appear to be larger than man-made 
devices of similar design and yield, presumably due to the neutron 
moderating effect of the water that separates the uranium masses 
throughout much of the device's construction. A given assembly 
area typically has between one and three devices in the process of 
assembly at any given time, although as many as six at a time has 
been observed. In zones where multiple devices are being 
simultaneously assembled, the devices are separated by enough 
distance to prevent the detonation of one from destroying or setting 
off the other(s). 


While the Foundation is unable to prevent civilians and other 
organizations from obtaining samples of SCP-118, its superficial 
similarity to existing species, few numbers (relative to all oceanic 
protista), lack of anomalous behavior outside material rich bodies of 
water, and the Foundation's standard monitoring of scientific studies 
at risk of uncovering information about anomalous biological species 
ensures that the chance of SCP-118's true nature being determined 
through cell samples is minimal. 


There are currently six different active SCP-118 assembly areas 
known to the Foundation. While the natural disappearance of an 
assembly area has been observed, the current consensus among 
researchers assigned to SCP-118 is that elimination of assembly 
areas without massively noticeable effects is currently unfeasible 
(See Experiment Log 118 - Gamma for details). Thus, containment 
is to be established at SCP-118's assembly areas, to be designated 
"Red Zones", and surrounding "Yellow Zones". Furthermore, areas 
with elevated concentrations of SCP-118, "Zones of Interest", are to 
be monitored for signs of assembly areas.

Location: South Pacific 
Coordinates: [REDACTED] 

Zone commander: Captain Knapp 


RZ -5 

Location: Indian Ocean 

Coordinates: [REDACTED] 

Zone commander: Captain Wayne 

Note: Proximity to shipping lanes reduces tolerance for 
nuclear explosions 


RZ-6 

Location: North Atlantic

Zone commander: Captain Fazil 

Note: Proximity to US SOSUS hydrophones reduces 
tolerance for nuclear explosions. 


RZ-7 

Location: [REDACTED] 

Coordinates: [REDACTED] 

Zone commander: Captain 

Note: Red Zone lies within city limits. This, 
combined with the shallow average depth of Red Zone, 
the heavy shipping traffic in the area, the ongoing 
tensions between and , a nuclear power, and the 
presence of Foundation personnel and facilities in the 
city makes a nuclear detonation in this Red Zone 
unacceptable. In addition, heavy ship traffic through the 
area and heavy air traffic above the city make restricting 
access for any long period of time impractical. 


Zones of Interest (ZOl) 


ZOI-1( N, E) - SCP-118 levels increasing 
around %5 per year, ZOI area growing approximately %3 
per year 

ZOI-3( N, W) - ZOI covers approximately 20 oil 
wells, SCP-118 levels and ZOI size currently stable. 


Former Zones (FZ) 


FZ-RZ-3( N, E) - Formerly RZ - 3, Last device 
assembled in 1992, SCP-118 levels dropped to average 
oceanic values in 20 

FZ-ZOI-2(  N, W) - Formerly ZOI - 2, SCP-118 
levels dropped to average oceanic values in 1986. 


Addendum-118-1: Following the USS Incident, the exclusion 
radius used when drawing red zones had been increased. 
Containment protocol TOXIC HARVEST has been updated. 


Addendum-118-2: With the signing of the Partial Test Ban Treaty 
and growing number and capability of nuclear detonation detection 
methods in use, the consequences of nuclear detonations caused 
by SCP-118 have increased. Containment protocols have been 
revised in light of these facts. 


Addendum-118-3: Due to the significant cost of containing 
SCP-118 Red Zones, the O-5 council has requested trials on 
possible methods to eliminate SCP-118 assembly areas. 


+ Experiment Log 118-Gamma - 
Level 4 clearance required 


Introduction: Researchers with access to the 
files on SCP-118 are allowed to submit 
proposals to eradicate an SCP-118 assembly 
area with acceptable levels of collateral 
damage. The ones approved by TOXIC 
HARVEST command and the 05 council will 
be carried out. Trials are to be performed in 
Red Zone . 


Proposal: Sterilization of unfinished nuclear 
device and immediate surroundings using a 
UV light emitter. 

Approval: Approved 

Result: Area around unfinished warhead 
initially free of micro-organisms, however 
SCP-118 concentration returned to normal 
levels within an hour. 

Non-sustained sterilization of sites seems 
ineffectual. Any method we come up with will 
have to keep the Red Zone, or at least the sea 
floor of it, free of SCP-118 for an extended 
period of time. -Dr Brant 


Proposal: Sodium Hypochlorite pumped to 
ocean floor. 

Approval: Denied 

Result: N/A 

The chemicals will disperse too much to be 
effective. Any amount sufficient to reduce 
SCP-118's numbers will cause massive 
ecological damage. -Dr Klaus 


Proposal: Depth charge bombardment of 
ocean floor to break up under-assembly 
devices 

Approval: Denied 

Result: N/A 

Aside from the fact this would break our naval 
budget, the chances of triggering the 
conventional explosive in the devices and 
causing a "fizzle" is too high. It would also 
make our activities even more detectable with 
hydrophones. -Dr Klaus 


Proposal: "Sweeping" of ocean using a 
Cobalt-60 powered directional gamma ray 
emitter. 

Approval: Approved 

Result: While procedure resulted in the 


sterilization of "swept" area, procedure was far 
too slow to sterilize entire Red Zone before 
specimens returned. Keeping entire Red Zone 
sterile would require impractical numbers of 
emitters and vessels. 

While it's a shame the device can not get rid of 
the Red Zones for us, | think it can be of use to 
our device recovery teams. The gamma rays 
can sterilize the devices we recover to prevent 
undesired detonations during the recovery of 
almost complete devices. The gamma rays 
can also penetrate into areas where our 
current chemical and UV sterilization methods 
can't reach -Captain Thomson (RZ-3 Zone 
Commander) 


Proposal: A plastic membrane to block 
access to ocean floor at Red Zone 

Approval: Proof of concept on one under- 
assembly warhead approved 

Result: First attempt was unable to acquire a 
water-tight seal around warhead. Membrane in 
second attempt was too fragile for ocean 
conditions and was torn off its moors. Third 
membrane, manufactured using a thicker and 
sturdier design, had hundreds of micro tears 
ripped in it within hours, possibly due to 
SCP-118's "mining" action. 

Not surprising, considering that SCP-118 has 
been known to wear through the casings of old 
artillery shells to harvest the explosives within. 
We had hoped that cutting off the assembly 
area would work better than cutting off the raw 
materials. -Dr. Klaus 


Proposal: Compound pumped to ocean 
floor. 

Note: Proposed by Dr. , former 
researcher for SCP-118 currently working at 
Bio Research Site 's Chemical Research 


Division. Tests confirm that compound is lethal 
to SCP-118, remains concentrated at bottom 
of water, and degrades into relatively harmless 
chemicals in water over a period of 15 hours. 
Approval: Approved 

Result: Over one week, SCP-118 
concentrations on ocean floor fell to 3% of 
previous levels. No signs of progress observed 
on two known uncompleted nuclear devices in 
Red Zone. However, 100 days after the start of 
the experiment an under assembly nuclear 
device was detected 60 km North of the Red 
Zone. Measurements in the area indicated 
vastly elevated levels of SCP-118 and the area 
around discovery was reclassified as a Red 
Zone. Furthermore, the unexpected 
breakdown of Compound by certain 
species of oceanic bacteria resulted in toxic 
byproducts that caused a noticeable die-off of 
fish in treated zone. Upon stoppage of 
experiment Red Zone was observed to 
gradually "migrate" back to former location. 

It seems that making a Red Zone non-viable 
served only to move SCP-118's assembly 
areas to a new location. Nevertheless, 
perhaps if we can improve Compound or 
find a new one whose application is more 
subtle we can move Red Zones into areas 
away from areas of human habitation or 
commercial activity. -Dr. 


Proposal: Use of SCP- via 


Approval: Denied 

Result: N/A 

SCP- has Classified properties that preclude 
its use in such a manner. -O5-5 


Conclusion: Due to increased media attention 
to areas around Red Zone due to aftermath 


of the application of Compound and the 
lack of proposals without high risks of 
substantial collateral damage, testing in Red 
Zone has been suspended. 


Addendum-118-4 (Level 4 Clearance required): 


Our research has determined SCP-118 enriches uranium 
by exploiting the fact that U-235 has a slightly greater 
preference for a high oxidation state than U-238. 
SCP-118 specimens which have harvested large 
amounts of uranium and are near assembly areas 
appear to develop specialized organelles resembling a 
series of thousands of vacuole-like chambers with 
mitochondria-like organelles within them, responsible for 
catalyzing reduction and oxidation reactions. In a given 
chamber, uranium is repeatedly reduced and oxidized. 
Compounds with uranium in higher oxidation states are 
transferred up the "chain" of chambers while compounds 
with lower oxidation states are transferred down the 
chain. This results in a small amount of highly enriched 
uranium at the very end of the chain. 


Researchers and engineers at Research Sector have 
managed to create a prototype uranium enrichment 
device based on the principles employed by SCP-118. 
While the prototype was unable to produce weapons- 
grade uranium without using unreasonable amounts of 
time, it was successful in producing reactor-grade 
uranium, albeit at significantly greater cost than 
conventional methods. Despite its current limitations, the 
idea shows promise and | have forwarded our findings to 
the relevant front companies.

SCP-119: Timecrowave 


Item #: SCP-119 
Object Class: Euclid 


Special Containment Procedures: SCP-119 is to remain open and 
unplugged at all times except during testing. The door to the room in 
which SCP-119 resides is to be locked for all periods except during 
experimentation, with the entry codes given only to authorized 
research and security personnel. An industrial-grade disinfectant will 
be available nearby at all times, and the inside of SCP-119 is to be 
heavily disinfected before any testing. The contents of SCP-119 are 
to be monitored through the viewing window on SCP-119 at all times 
during testing, and will be stopped immediately should the contents 
become hostile or otherwise damaging to SCP-119. 


Description: SCP-119 is a Panasonic [REDACTED] Microwave 
Oven. It was initially discovered by an agent, who had bought it from 
a liquidation sale of the assets from Valley Vineyards. It is 
believed that Valley Vineyards was using the anomalous 
properties of SCP-119 to rapidly age its products and create 
expensive vintages. Records show __ Valley Vineyards making 
under-the-table sales of vintages dated as far back as 19 , many 
years before the company's inception in 2005. These sales are what 
led to the lawsuits accusing the company of falsifying product 
information and other forms of fraud, which eventually caused 
Valley Vineyards to declare bankruptcy. SCP-119 appears to be a 
standard model of microwave in all respects except that the 
magnetron unit does not produce microwave radiation. Instead, the 
magnetron emits a previously unknown type of radiation that 
accelerates time. 


The amount of time accelerated is based on the time input given at 
the start, and the power level setting. The time input allows for three 
digits, and there are five power level settings. On power level 1, the 
number of seconds input equals the number of seconds experienced
